With over 400 locations across Australia, Hungry Jack's is the second-largest franchise of Burger King in the world (second to Carrols Corporation, which is now owned by Restaurant Brands International).

In October 1981, the company opened its first New South Wales store in the Sydney central business district on the corner of Liverpool and George Street.

In 1996, shortly after the Australian trademark on the Burger King name lapsed, Burger King Corporation made a claim that Hungry Jack's had violated the conditions of the renewed franchise agreement by failing to expand the chain at the rate defined in the contract and sought to terminate the agreement.

[15][16] After Burger King Corporation lost the case, it decided to terminate its operations in the country and in July 2002 the company transferred its assets to its New Zealand franchise group, Trans-Pacific Foods (TPF).

[citation needed] An additional part of the agreement required Burger King Corporation to provide administrative and advertising support as to ensure a common marketing scheme for the company and its products.

[5][9] In the 2009 to 2010 financial year, Competitive Foods Australia reported an after-tax profit of $32.1 million on sales of $1.043 billion.

[24][25] Hungry Jack's breakfast menu, introduced in late 2005 in two states, Queensland and Western Australia, as well as the Northern Territory, and the other states the following year, bears little resemblance to Burger King's US breakfast menu, and includes items such as English muffins and toasties.

[33] The pilot scheme was perceived as being successful and the coffee brand was rolled out to all Hungry Jack restaurants in Australia in June of the same year.

[39] Hungry Jack's had also ran an advertising campaign that made light of the lawsuit during the early stages of the trial which also made the claim that the Big Jack patty was 25% larger than the Big Mac's as a point of differentiation; the Court found this claim misleading but it did not affect the final verdict.

The burger and all its variants were removed from the menu in late 2021, though it returned as a limited time item in May 2024 after the suit was resolved.
