What does this bill do?

Big mergers that meet future thresholds will have to be reported to the Australian Competition and Consumer CommissionThe regulator that will check big mergers before they complete and decide whether they should be allowed. before they can go ahead.

Why was it introduced?

Australia’s current merger control system left anti-competitive mergers too hard to stop and needed a faster, stronger and simpler process. The bill requires big deals to be notified before completion, lets the ACCCThe regulator that will check big mergers before they complete and decide whether they should be allowed. decide them under set timelines, and allows Tribunal review.

Broader context

Australia’s merger rules had largely relied on an older system that the government said was no longer strong enough to stop anti-competitive deals, especially as high market concentration, weak productivity and cost-of-living pressure made competition policy more urgent. The bill responded by shifting Australia to a mandatory, ACCCThe regulator that will check big mergers before they complete and decide whether they should be allowed.-led pre-merger clearance system with set timelines and review rights, and it completed that change when Parliament passed it in November 2024 and Royal AssentThe final step that turns a passed bill into an Act of Parliament. followed in December.

Key criticism

The main criticism was that the new merger regime could impose a heavy compliance burden and slow deals, especially for small businesses and start-ups, if the ACCCThe regulator that will check big mergers before they complete and decide whether they should be allowed. is under-resourced or the rules are implemented poorly. That concern was raised most clearly by the Coalition and echoed more narrowly by some crossbench supporters, who backed the bill overall but wanted the 12-month review, resourcing and safeguards taken seriously.

The main case against this bill

The main criticism was that the new merger regime could impose a heavy compliance burden and slow deals, especially for small businesses and start-ups, if the ACCCThe regulator that will check big mergers before they complete and decide whether they should be allowed. is under-resourced or the rules are implemented poorly. That concern was raised most clearly by the Coalition and echoed more narrowly by some crossbench supporters, who backed the bill overall but wanted the 12-month review, resourcing and safeguards taken seriously.

No party represented in the debate opposed the bill, but some support was clearly conditional on implementation.

Compliance burden and implementation risk

Critics warned the regime could add a substantial economy-wide compliance burden and make mergers harder or slower than necessary, particularly for small businesses and start-ups, if the ACCCThe regulator that will check big mergers before they complete and decide whether they should be allowed. and government do not implement it carefully and resource it properly.

Broad ministerial discretion over thresholds

A narrower drafting concern was that the bill leaves too much power with the minister to set market-concentration thresholds, creating a risk that key settings could be made without enough independent competition advice.

  1. Sam Rae Sam Rae supports the bill, saying it modernises Australia’s merger laws by giving the ACCCThe regulator that will check big mergers before they complete and decide whether they should be allowed. mandatory notification powers, faster approval for low-risk deals and stronger scrutiny of harmful mergers.
    “The Albanese government's reforms will bring Australia's merger framework into the 21st century. These changes will establish a mandatory notification system, providing the ACCC with full visibility of significant transactions. This ensures that the regulator can focus on the mergers that pose the greatest risks to competition, while businesses pursuing beneficial transactions are supported with a streamlined and efficient process. The reforms will strengthen the ACCC's ability to act decisively. Pro-competitive mergers will advance quickly, with a clear pathway for approvals within 30 working days where there are no concerns for consumers. Harmful or risky transactions, on the other hand, will be scrutinised and, if necessary, prevented. This balance of ensuring markets are both dynamic and protected is critical to the health of our economy.”

  1. Kate Chaney Chaney supports the bill because she says it will improve merger transparency and competition, which should help lower prices for consumers.
    “These minor changes aside, the bill increases the transparency and scrutiny of private mergers and makes the regulation a mandatory reporting regime so that the ACCC can monitor how our business acquisitions are affecting competition. I recognise that we do need to reduce red tape so that businesses can get on with doing what they do best, particularly given our period of low productivity. I recognise that this will create a regulatory burden, particularly in the private equity sector. The coalition has pointed out some other concerns, such as ACCC resourcing and the compliance burden, and I respect that these need to be considered. But the benefits of this amendment could deliver for cost-of-living relief, and that's so important that I'm happy to support the passage of this bill, ideally with my amendments.”
