- Competition leads to lower prices, better quality products and services, and more choice for consumers.
- The Competition and Consumer Act 2010 bans business behaviours that damage competition.
- It is strictly illegal for businesses to collude in a cartel or impose minimum resale prices.
- A range of other behaviours break the law if they substantially lessen competition.
- Businesses can seek an exemption for potentially anti-competitive behaviour.
What the ACCC does
- We protect and promote competition in markets to benefit consumers, businesses and the community.
- We provide general information about businesses’ obligations under competition law.
- We investigate anti-competitive behaviour that may be illegal.
- We enforce the law on anti-competitive behaviour, and take action against businesses that break the law.
What the ACCC can't do
- We don’t intervene directly in disputes between businesses.
- We don’t give legal advice.
Australia’s open market economy depends on strong competition between businesses.
Competition encourages individual businesses to innovate and find ways to work more efficiently. This results in:
- lower prices
- better quality products and services
- more choice for consumers
- increased prosperity and welfare of all Australians.
For competition to stay healthy, businesses must behave in an acceptable way towards competitors and suppliers. The Competition and Consumer Act 2010 sets rules for business behaviour so that all businesses can compete on their merits.
Some behaviour is so damaging to competition that it’s banned outright.
It is strictly illegal for businesses to collude with competitors by fixing prices, rigging bids, sharing markets or controlling output as part of a cartel. These activities cheat consumers and other businesses and restrict economic growth.
Imposing minimum resale prices
The law also bans suppliers from setting minimum prices for the resale of their products or services. Imposing minimum resale prices stops retailers competing on price, increasing what consumers pay.
There are also a range of business behaviours that may damage competition, depending on the circumstances.
Business behaviour can break the law when it has the purpose, effect or likely effect of substantially lessening competition in a market.
This occurs when business behaviour interferes with or damages the competitive process in a market in a meaningful way, usually by deterring, hindering or preventing competition.
Competition is substantially lessened when, as a result of the business’s behaviour:
- the business’s competitors are restricted from competing effectively
- the business is able to significantly and sustainably increase its prices
- it would be very hard for a new business to set up and start competing.
Competition can also be substantially lessened when two or more businesses engage in conduct that weakens competition.
Cooperation among businesses
Generally, competition relies on businesses making independent decisions.
When businesses communicate and cooperate with each other, they risk damaging competition and breaking the law.
Misuse of market power
It's not illegal to have market power. However, businesses must not misuse this power to stop other businesses competing on their merits. When the misuse of market power substantially lessens competition, it is illegal.
Businesses also risk breaking competition law when they engage in exclusive dealing by restricting how their customers or suppliers do business. While exclusive dealing is common in legitimate business arrangements, it is illegal when it substantially lessens competition.
As long as a business is competing on its merits rather than trying to stop other businesses from competing, its behaviour is unlikely to break the law – even if a competitor’s business is harmed.
Businesses competing on their merits do things like:
- investing in research to improve products or services, or invent new ones
- advertising to win customers, without making false or misleading claims
- improving their processes to lower costs.
Behaviours like these benefit consumers and the economy, and are not illegal.
It’s not illegal to:
- innovate and launch new products which disrupt a market
- respond to price competition by offering lower prices
- open a shop of the same kind over the road from an existing shop
- refuse to supply another business, unless it substantially lessens competition, results from cartel conduct, or is part of resale price maintenance.
A business planning conduct or an arrangement that risks breaking competition law can seek an exemption from the ACCC.
An exemption gives the business protection from legal action for the conduct or arrangement.
The ACCC only exempts behaviour that doesn't substantially lessen competition, or is in the public interest.
See About exemptions for the different exemption processes and when they can be used.
