Mobil Oil Australia, through its predecessor company, Vacuum Oil, opened its first branch in Queen Street, Melbourne in February 1895. Esso Australia's origins go back to late 1927 when the Union Oil Company of California and the Atlantic Refining Company decided to combine to enter the Australian and New Zealand markets.
The global merger of Exxon Corporation and Mobil Oil Corporation on 30 November 1999 heralded the creation of the world's largest publicly traded oil and gas company, Exxon Mobil Corporation. Within Australia the merger provided opportunities to rationalise resources whilst retaining the Mobil and Esso brands. Today, ExxonMobil in Australia is part of the world's premier petroleum and petrochemical company.
Esso Australia has been one of Australia's most successful oil and gas production companies.
