Petrol, diesel and automotive LPG prices are not regulated in Australia. Automotive LPG prices were deregulated in 1991, and petrol and diesel prices were deregulated in 1998. However, in the interests of consumers and competitive markets, the ACCC continues to monitor fuel prices in Australia’s largest capital cities and more than 190 regional locations.


Mergers and acquisitions are important for the efficient functioning of the economy. They allow firms to achieve efficiencies and diversify risk across a range of activities. However, the Competition and Consumer Act prohibits mergers that would have the effect, or be likely to have the effect, of substantially lessening competition in a market.


The ACCC’s regulatory work in rail includes assessing Part IIIA undertakings submitted by rail access providers in relation to rail track infrastructure, and carrying out functions under accepted undertakings. To date only one rail infrastructure provider, the Australian Rail Track Corporation, has submitted access undertakings under Part IIIA of the Act. Two access undertakings are currently in place, one for the National Interstate Rail Network and one for the Hunter Valley Rail Network in New South Wales.


The ACCC’s role in energy covers market inquiries in relation to the electricity and gas sectors. The ACCC also enforces the Competition and Consumer (Industry Code – Electricity Retail) Regulations 2019 and Part XICA of the Competition and Consumer Act 2010, which prohibits misconduct in the electricity market. In addition, the ACCC is also working on a Consumer Data Right in relation to energy.

Airports & aviation

The ACCC has a number of roles in relation to airports and aviation services. These roles are primarily related to promoting transparency about services that may be provided in sectors with little or no competition. We do not have any regulatory responsibilities in relation to the industry.
