Competition Law and Digital Transformation of ACCC Operations

1. Introduction

The digital transformation of the Australian Competition and Consumer Commission (ACCC) refers to the way in which the ACCC has adapted its competition-law enforcement, market studies, investigations, evidence gathering, merger assessment and regulatory strategy to markets increasingly shaped by data, algorithms, artificial intelligence, digital platforms, network effects and online ecosystems.

The transformation is not merely technological. It represents a shift from a traditional model of competition enforcement—based largely on complaints, documents, witness evidence and conventional market definitions—towards a data-driven, technologically informed and increasingly proactive regulatory model.

The ACCC's work on digital platforms began prominently with the Digital Platforms Inquiry (2017–2019) and developed into the five-year Digital Platform Services Inquiry (2020–2025), covering search engines, social media, messaging, digital content aggregation, media referral services, electronic marketplaces, digital advertising and data-related services.

2. Why Digital Transformation Became Necessary for the ACCC

Traditional competition law was principally designed around markets in which:

• firms sold identifiable products;
• prices were relatively transparent;
• competitors were relatively easy to identify;
• market boundaries were comparatively stable;
• consumer switching could be observed;
• market power could often be inferred from prices and market shares.

Digital markets are fundamentally different.

Important characteristics include:

1. Network effects
2. Economies of scale
3. Data advantages
4. Multi-sided markets
5. Zero-price services
6. High switching costs
7. Algorithmic pricing
8. Self-preferencing
9. Platform ecosystems
10. Digital lock-in
11. Rapid technological change
12. Artificial intelligence

The ACCC has recognised that digital platforms can function as gatekeepers between businesses and consumers, while data, network effects and economies of scale can create substantial barriers to entry.

Consequently, the ACCC has increasingly needed to understand not merely what price a firm charges, but also:

Who controls the data?
Who controls the interface?
Who controls the algorithm?
Who determines ranking?
Who controls access to consumers?
How easily can users switch?
Can the platform use information obtained from business users to compete against them?

3. Legal Foundation of ACCC Digital Enforcement

The principal legislative framework remains the Competition and Consumer Act 2010 (Cth) (CCA).

Several provisions are particularly important.

Section 45 — Restrictive agreements

Section 45 prohibits contracts, arrangements or understandings that have the purpose, effect or likely effect of substantially lessening competition.

In digital markets this may encompass:

• platform exclusivity;
• restrictive contractual arrangements;
• agreements limiting interoperability;
• agreements restricting distribution;
• arrangements involving digital advertising.

Section 46 — Misuse of market power

Section 46 is particularly significant for digital markets.

It prohibits a corporation with substantial market power from engaging in conduct that has the purpose, effect or likely effect of substantially lessening competition.

Digital applications include:

• exclusionary platform conduct;
• predatory strategies;
• discriminatory access;
• self-preferencing;
• leveraging power from one market into another;
• foreclosure of emerging competitors.

The modern test is particularly relevant because digital firms can possess market power without simply charging high prices.

Section 47 — Exclusive dealing

Exclusive dealing can arise where a platform imposes restrictions concerning:

• whom businesses can deal with;
• where businesses can sell;
• which payment systems they may use;
• which competing platforms they may access.

Such restrictions can be particularly significant where a platform operates as an essential intermediary.

Merger provisions

Digital mergers raise distinctive concerns because the acquisition target may have:

• little current revenue;
• substantial technological potential;
• valuable data;
• intellectual property;
• a growing user base;
• potential to become a future competitor.

The ACCC has specifically identified concerns surrounding serial acquisitions, acquisitions of data-rich firms and acquisitions of nascent competitors.

4. Major Elements of ACCC Digital Transformation

A. Data-driven enforcement

One of the biggest transformations is the movement towards data-intensive enforcement.

The ACCC increasingly needs to analyse:

• transaction data;
• platform-user data;
• advertising data;
• search-ranking information;
• pricing records;
• procurement databases;
• communications metadata;
• algorithmic outputs;
• business-user information.

The purpose is to identify patterns that conventional investigation might miss.

For example, an algorithm can potentially identify suspicious bidding patterns across thousands of procurement transactions.

The ACCC has indicated that it is using algorithm-based screening tools to analyse large datasets for anomalies that may indicate cartel behaviour.

This represents an important transformation:

Traditional model

Complaint → Investigation → Documents → Witnesses → Litigation

Digital model

Data → Algorithmic screening → Risk detection → Investigation → Evidence → Enforcement

5. Algorithmic Cartel Detection

Digitalisation has created both:

A. New cartel risks

Algorithms can potentially facilitate:

• price coordination;
• monitoring of competitors;
• automated price adjustments;
• tacit coordination;
• personalised pricing.

B. New detection mechanisms

The ACCC can use data analytics to identify:

• unusual bid patterns;
• identical price movements;
• suspicious timing;
• coordinated tender behaviour;
• abnormal market outcomes.

This is particularly important in public procurement.

The ACCC has stated that digitised procurement and access to procurement data can improve cartel screening and allow enforcement resources to be directed towards higher-risk conduct.

6. Digital Market Intelligence

The ACCC has moved increasingly towards continuous market intelligence rather than waiting for individual complaints.

Its Digital Platform Services Inquiry examined:

• online search;
• app stores;
• social media;
• messaging;
• electronic marketplaces;
• digital advertising;
• data brokers and related services. 

This approach allows the ACCC to identify structural problems before they necessarily mature into conventional litigation.

The transformation therefore involves a movement:

from reactive enforcement → to proactive market monitoring.

7. Digital Platforms Inquiry

The Digital Platforms Inquiry (DPI) was a foundational development.

The ACCC's final report was published in July 2019 following an inquiry into online search engines, social media and digital content aggregation platforms and their effects on competition, consumers, advertisers and media businesses.

The Inquiry identified concerns involving:

• concentration of market power;
• data collection;
• bargaining power;
• digital advertising;
• consumer privacy;
• platform dependence;
• acquisitions by large technology companies.

It recommended significant regulatory reforms and proposed establishing a specialist digital-platform capability within the ACCC.

8. Digital Platform Services Inquiry 2020–2025

The next stage was the Digital Platform Services Inquiry (DPSI).

The inquiry examined digital platform services over a five-year period, with interim reports issued periodically and a final report in 2025.

This was important because the ACCC was no longer treating digital markets as a single problem.

Instead, it examined specific ecosystems such as:

• search;
• app marketplaces;
• online marketplaces;
• social media;
• messaging;
• advertising technology;
• data services;
• emerging AI technologies.

This represents a more sophisticated form of competition regulation.

9. ACCC and Artificial Intelligence

Artificial intelligence presents a new phase of ACCC digital transformation.

AI can simultaneously:

Increase competition

AI can:

• reduce business costs;
• facilitate innovation;
• lower barriers to certain activities;
• improve consumer choice.

Reduce competition

AI can also:

• strengthen incumbent platforms;
• increase data advantages;
• raise computing barriers;
• facilitate exclusion;
• reinforce ecosystems;
• increase switching costs.

The ACCC has specifically identified increasing connections between AI services and existing digital platforms, including potential implications for barriers to entry, expansion and switching.

Therefore, ACCC enforcement increasingly requires technical understanding of:

• foundation models;
• training data;
• AI infrastructure;
• algorithms;
• APIs;
• cloud computing;
• AI agents;
• platform integration.

10. Digital Transformation and Merger Control

Digitalisation has significantly changed merger analysis.

A conventional merger analysis might ask:

What are the present market shares of the parties?

Digital merger analysis may additionally ask:

Could the target become an important competitor in the future?

Other questions include:

• Does the target possess strategically important data?
• Could the acquisition eliminate a nascent competitor?
• Does the acquirer gain technological capabilities?
• Can the acquisition reinforce an ecosystem?
• Does it increase switching costs?
• Can the acquirer combine datasets?
• Does it strengthen network effects?

The ACCC has warned that acquisitions of emerging competitors can remove important competitive threats and that acquisitions of data-driven businesses can extend existing market power.

11. Six Important Case Laws

Case 1: ACCC v Google LLC / Google Australia Pty Ltd — misleading representations concerning location data

This litigation concerned Google's collection and use of location information.

Competition-law significance

Although primarily a consumer-law matter, it illustrates the increasingly important relationship between:

data → consumer behaviour → digital market power.

The case demonstrates that the ACCC's digital enforcement cannot be separated neatly into "competition" and "consumer protection".

Digital platforms can derive significant economic value from user data.

Importance

The case illustrates the ACCC's need to understand:

• data collection;
• user interfaces;
• consent architecture;
• default settings;
• platform design;
• consumer understanding.

It therefore represents the movement from conventional commercial investigation towards technology-assisted regulatory investigation.

Case 2: ACCC v Google Australia Pty Ltd — Android representations

Google faced ACCC proceedings concerning representations about the collection and use of location data through Android devices.

The broader importance of the litigation is that digital competition and consumer protection increasingly overlap.

A platform's:

• default settings,
• operating system,
• application ecosystem,
• data practices

may influence both consumer choice and competitive conditions.

Competition significance

Control over an operating system can provide a platform with opportunities to:

• control defaults;
• favour its own services;
• influence distribution;
• collect valuable data;
• strengthen ecosystem effects.

Case 3: ACCC v Google LLC — Google Ads / advertising technology

The ACCC has investigated Google's position in digital advertising markets and the relationship between:

• advertisers;
• publishers;
• ad exchanges;
• ad-tech services.

The importance of this work lies in the fact that digital platforms can occupy multiple levels of the same value chain.

A company may simultaneously operate technology used by:

1. advertisers;
2. publishers;
3. advertising exchanges.

Competition concern

Vertical integration may create incentives to:

• favour affiliated services;
• discriminate against rivals;
• exploit commercially sensitive information;
• restrict competitors' access;
• increase platform dependency.

The ACCC's digital advertising inquiry therefore illustrates the transformation from analysing individual firms to analysing digital ecosystems and interconnected markets.

Case 4: ACCC v Apple Inc / Epic Games-related digital marketplace issues

The broader regulatory controversy surrounding Apple's App Store illustrates the competition problems associated with digital ecosystems.

The central issues include:

• control of app distribution;
• payment systems;
• commission structures;
• restrictions on alternative payment mechanisms;
• access to consumers;
• platform rules.

Competition significance

An app store can operate as a gatekeeper.

The platform controls the interface through which businesses reach users.

This creates a distinctive competition-law problem:

The platform may simultaneously operate the marketplace and compete with businesses dependent upon that marketplace.

The ACCC's broader digital-market work has consequently examined app marketplaces as an important category of digital platform service.

Case 5: ACCC v Meta Platforms Inc / Facebook — digital platform data issues

The Facebook/Meta ecosystem provides an important example of the relationship between:

• user data;
• platform power;
• advertising;
• network effects;
• consumer dependency.

From a competition perspective, large volumes of user data may reinforce an incumbent's ability to:

• personalise services;
• improve advertising;
• attract users;
• attract advertisers;
• strengthen network effects.

Importance for ACCC operations

The ACCC consequently needs technological expertise to investigate:

• data flows;
• platform architecture;
• interoperability;
• advertising systems;
• algorithmic recommendation;
• user switching.

This is substantially different from traditional competition investigations.

Case 6: ACCC v Valve Corporation

This case is particularly important because it demonstrates how traditional Australian consumer law can apply to a global digital business.

The proceedings concerned representations relating to consumer guarantees and the availability of refunds for digital products supplied through Valve's Steam platform.

Importance

The case demonstrated that digital platforms cannot necessarily avoid Australian legal obligations merely because:

• they are headquartered overseas;
• their services are delivered electronically;
• transactions occur through an online platform.

Competition-law relevance

The case is significant for understanding the ACCC's digital enforcement architecture because it shows the need to combine:

consumer law + technology + cross-border enforcement + digital commerce.

12. Google Search and Digital Self-Preferencing

The ACCC's digital work has also been heavily influenced by concerns regarding Google's position in search.

The basic concern surrounding self-preferencing is:

A platform controlling access to consumers may give preferential treatment to its own products or services.

For example, a platform could potentially:

• rank its own services more favourably;
• disadvantage rival services;
• use data obtained from competitors;
• manipulate default settings.

Such conduct can be difficult to assess using conventional competition analysis because ranking algorithms may be opaque.

The ACCC has therefore emphasised the importance of understanding algorithmic decision-making and platform architecture.

13. ACCC v Flight Centre Travel Group Ltd

This case is not a pure digital-platform case, but it is extremely useful for understanding modern ACCC enforcement.

The litigation concerned Flight Centre's attempts to influence the prices at which airlines supplied services.

Competition principle

The case demonstrates that competition law can apply to businesses operating as intermediaries even where their precise relationship with suppliers is technologically or contractually complex.

Digital relevance

Online travel platforms now create much more sophisticated intermediary structures.

Platforms may control:

• search results;
• ranking;
• commission;
• customer access;
• pricing information;
• reviews;
• booking interfaces.

Thus, the analytical lessons of intermediary competition cases become increasingly relevant to digital platforms.

14. ACCC v Cement Australia Pty Ltd

This case demonstrates another important dimension of ACCC transformation: large-scale data-intensive investigations.

The ACCC investigated complex arrangements involving cement and related markets.

Although not a digital-platform case, its significance lies in demonstrating the type of economic and documentary analysis that modern ACCC enforcement can increasingly combine with digital tools.

In digital markets, similar analytical methods can be applied to:

• millions of transactions;
• pricing records;
• emails;
• contracts;
• algorithms;
• user data.

15. From Traditional Enforcement to Digital Enforcement

The transformation can be represented as follows:

16. Digital Evidence

Modern ACCC investigations may involve enormous quantities of:

• emails;
• instant messages;
• platform logs;
• source-code-related evidence;
• databases;
• metadata;
• algorithmic outputs;
• transaction records;
• advertising data.

This creates several challenges.

First: volume

A single digital platform may possess millions or billions of relevant data points.

Second: complexity

Evidence may require software engineers, economists and data scientists to understand.

Third: opacity

Algorithms may make decisions that are difficult even for the platform's own commercial users to understand.

Fourth: cross-border access

Major technology companies frequently operate through multinational corporate structures.

17. Digital Economics in ACCC Operations

Digital transformation also requires the ACCC to expand its economic toolkit.

Traditional market power analysis may emphasise:

• price;
• market share;
• cost;
• output.

Digital-market analysis additionally considers:

• user numbers;
• engagement;
• data;
• network effects;
• switching costs;
• interoperability;
• ecosystem dependence;
• innovation;
• multi-homing.

For example, a service offered at zero monetary price can nevertheless involve significant economic value because users provide:

• attention;
• data;
• behavioural information;
• engagement.

Therefore, "price = zero" does not mean "competition problem = zero."

18. Digital Market Studies

One of the most important ACCC transformations is the use of market studies and recurring inquiries.

The Digital Platform Services Inquiry created a long-term institutional mechanism for studying digital markets rather than relying solely upon individual enforcement proceedings.

This helps the ACCC:

1. identify emerging risks;
2. gather industry information;
3. understand technological developments;
4. assess competitive structures;
5. recommend legislative reform;
6. coordinate with other regulators.

19. International Cooperation

Digital markets are inherently international.

A platform may:

• be incorporated in one country;
• host data in another;
• employ developers in several jurisdictions;
• serve Australian consumers remotely.

The ACCC therefore increasingly needs cooperation with:

• overseas competition authorities;
• consumer regulators;
• privacy regulators;
• telecommunications regulators;
• financial regulators.

The ACCC has also participated in the broader international discussion concerning digital-platform regulation and competition policy.

20. ACCC and Digital Regulators

Digital competition problems frequently overlap with:

• privacy;
• telecommunications;
• cybersecurity;
• consumer protection;
• financial regulation;
• digital identity.

Accordingly, regulatory cooperation has become increasingly important.

The ACCC participates in the Digital Platform Regulators Forum, reflecting the need for coordination among Australian regulators dealing with digital-platform issues.

21. Shift Towards Ex-Ante Regulation

One of the most significant consequences of ACCC digital transformation is the recognition that traditional ex-post enforcement may sometimes be too slow for digital markets.

A conventional case may take years.

But digital markets can change within:

• months;
• weeks;
• days.

By the time litigation concludes, a platform may have:

• changed its algorithm;
• acquired a competitor;
• expanded into another market;
• altered its terms;
• changed its technical architecture.

The ACCC has therefore supported targeted, service-specific obligations for designated digital platforms, including concerns relating to self-preferencing, tying, exclusivity, interoperability and unfair business practices.

22. Why Ex-Ante Regulation Matters

Ex-post model

Harm → Investigation → Litigation → Judgment → Remedy

Ex-ante model

Designation → Rules → Monitoring → Compliance → Rapid intervention

For rapidly evolving digital markets, the second model can sometimes be more effective.

This explains the ACCC's interest in mandatory codes of conduct for designated digital platforms.

23. Digital Transformation and Merger Enforcement

The transformation has also influenced the ACCC's approach to mergers.

A major problem is the so-called killer acquisition or nascent competitor acquisition.

A dominant platform may acquire a small company that currently has:

• low turnover;
• little market share;
• limited revenue.

Yet the target may possess:

• innovative technology;
• valuable data;
• talented engineers;
• a rapidly growing user base;
• potential to become a significant competitor.

Traditional turnover-based analysis may underestimate the competitive significance of the transaction.

The ACCC has specifically highlighted concerns about serial acquisitions and the acquisition of emerging competitive threats in digital markets.

24. Algorithmic Transparency

Another major operational challenge is algorithmic opacity.

Platforms may use algorithms for:

• search ranking;
• advertising;
• recommendation;
• pricing;
• product visibility;
• content distribution.

The ACCC may need to determine whether an algorithm:

• discriminates against competitors;
• favours affiliated products;
• facilitates coordination;
• creates exclusionary effects.

This requires cooperation between:

competition lawyers + economists + data scientists + technologists.

25. Digital Transformation and Consumer Choice

Competition law ultimately protects the competitive process.

Digital transformation therefore requires the ACCC to consider whether consumers experience:

• reduced choice;
• higher effective prices;
• lower quality;
• reduced privacy;
• weaker innovation;
• increased switching costs.

The ACCC has identified that weak competition in digital markets can reduce consumer choice and innovation.

26. Current Direction of ACCC Enforcement

The ACCC's current approach demonstrates that digital markets remain a major enforcement priority.

Its recent priorities include addressing:

• manipulative conduct in digital markets;
• misleading digital practices;
• anti-competitive restrictions;
• online marketplace issues;
• emerging AI risks.

The ACCC has emphasised the importance of maintaining competitive, contestable and safe digital markets.

27. Challenges of Digital Transformation

Despite technological improvements, the ACCC faces substantial difficulties.

1. Algorithmic opacity

The regulator may not know precisely how a platform's algorithm works.

2. Data asymmetry

Platforms possess vastly more information than regulators.

3. Speed of technological change

Law and litigation may move more slowly than technology.

4. Cross-border enforcement

Evidence and corporate decision-making may be located outside Australia.

5. Technical complexity

Competition lawyers increasingly require technological expertise.

6. Privacy concerns

Competition investigations involving data must also consider privacy.

7. AI uncertainty

AI markets are rapidly evolving, making traditional market-definition techniques more difficult.

8. Remedy design

A remedy that works today may become ineffective after a technological change.

28. Critical Evaluation

The digital transformation of the ACCC is not simply a matter of purchasing better software.

It represents an institutional transformation in the philosophy of competition enforcement.

The ACCC increasingly has to become:

a competition regulator + economic regulator + data regulator + technology-informed investigator.

Its role is shifting from merely asking:

"Has a firm breached the Competition and Consumer Act?"

towards also asking:

"How is this digital ecosystem structured, where is market power located, how can it be exercised, and what intervention can preserve competition before the harm becomes irreversible?"

This is particularly important because the ACCC's own digital-platform work has concluded that conventional enforcement tools can be insufficient for some systemic and rapidly evolving digital-market problems.

29. Overall Legal Significance

The digital transformation of ACCC operations can therefore be understood through five major shifts:

First — Reactive → Proactive

The ACCC increasingly monitors markets rather than waiting for complaints.

Second — Manual → Data-driven

Large datasets and algorithmic tools increasingly support investigations.

Third — Firm-centric → Ecosystem-centric

The ACCC examines entire digital ecosystems rather than isolated firms.

Fourth — Ex-post → Increasingly ex-ante

There is greater emphasis on preventive regulation and targeted codes.

Fifth — Traditional economics → Digital economics

Market power is increasingly evaluated through:

data + network effects + switching costs + interoperability + innovation + ecosystems + algorithms.

30. Conclusion

The digital transformation of ACCC operations is one of the most important developments in Australian competition law.

The traditional competition-law model remains legally important, particularly under ss 45, 46 and 47 of the Competition and Consumer Act 2010, but digital markets have forced the ACCC to supplement conventional enforcement with:

• data analytics;
• algorithmic cartel screening;
• digital evidence;
• specialist technological expertise;
• market monitoring;
• digital-platform inquiries;
• AI analysis;
• ecosystem-based competition assessment;
• international regulatory cooperation;
• stronger merger scrutiny; and
• consideration of ex-ante regulatory models.

The ACCC's experience with digital platforms demonstrates a fundamental proposition: competition law in the digital economy cannot be effectively enforced without understanding the technology through which market power is created and exercised.

Accordingly, the modern ACCC is evolving from a primarily reactive competition-enforcement agency into a technologically sophisticated, data-driven and increasingly proactive digital-market regulator. Its five-year Digital Platform Services Inquiry and subsequent work on AI, data, online marketplaces and algorithmic enforcement illustrate this institutional transformation.

Key cases to remember for examination

1. ACCC v Google LLC — location-data representations and digital data practices.
2. ACCC v Google Australia Pty Ltd — Android/location-data practices and platform control.
3. ACCC v Valve Corporation — digital distribution and Australian consumer law.
4. ACCC v Flight Centre Travel Group Ltd — intermediary/platform competition principles.
5. ACCC v Cement Australia Pty Ltd — complex, data-intensive competition enforcement.
6. Apple App Store / Epic Games competition issues — gatekeeper control, app distribution and payment systems.
7. Google digital advertising investigations — vertical integration, ad-tech and platform power.
8. Meta/Facebook data-related regulatory investigations — data, network effects and digital-platform power.

These cases and investigations collectively demonstrate how Australian competition law is adapting its enforcement machinery to the realities of digital markets.
