Assistant Competition, Charities and Treasury Minister Andrew Leigh has discussed the beer "duopoly" with Australians paying "too much" for the alcohol.

This comes amid the nation-wide increase in beer prices.

“The beer industry in Australia is essentially a duopoly,” Mr Leigh told Sky News Australia.

“The impact of that duopoly had been that Australians were paying too much for beer.

“It's important to make sure that we get more competition into the economy.”
