[1][2] Goldberg negotiated an agreement with Mobil Australia, for the supply of petroleum at a fixed rate, following the increase in world fuel prices, this discount increased from six cents to 12.5 cents per gallon.
[3] In July 1975, it joined forces with the Australian Council of Trade Unions to sell discounted fuel to independent operators in Melbourne.
[7] In 1989 the business was sold to Ampol by which time it was the largest independent fuel retailer and distributor with over 200 service stations.
[8][9] Goldberger and Wieland were subject to a ten year non-compete clause however this was ruled void by the Trade Practices Commission after Ampol merged with Caltex, allowing them to establish Liberty Oil in 1995.
