[2][3][4] By 1963, assembly of Toyota vehicles in Australia by Australian Motor Industries (AMI) had begun, taking place at the production plant in Port Melbourne.

In 1972 Toyota bought out British Leyland's interest in AMI[5] and announced plans to spend $127 million on an engine and gearbox plant.

[10] In 1987, under the leadership of Robert Johnston, Toyota Australia and Holden formed United Australian Automobile Industries in response to the Button car plan.

[9] Many Toyota vehicles have been built at either Altona or Port Melbourne, including the Tiara, Corona, Crown, Corolla, Camry and Avalon.

[11] The first locally-made Australian Toyota Hybrid Camry was completed and revealed to public on 11 December 2009, driven by Prime Minister Kevin Rudd.

[14] The company consolidated its corporate functions in Melbourne at the end of 2017 when its Sales & Marketing operation relocated from Woolooware Bay, Sydney.

Head office (CHQ) remained in Port Melbourne and the Altona plant was retained for other functions including a Centre of Excellence and vehicle proving facility known as the Autodrome.

[citation needed] in February 2014, Toyota Australia announced its decision to close its manufacturing plant by the end of 2017 and become a national sales and distribution company.

The plant produced the Camry and Aurion for sale locally in Australasia and for export to the Middle East, as well as the Corolla until the switch to the fully imported 8th Generation.

[16] On 11 December 2009, manufacture of the first locally-made Camry Hybrid was completed and revealed to the public, writing a new page in the history of the Australian automotive industry.

[18] In March 2019, Toyota announced plans to build a Hydrogen Centre at Altona partly funded by the Australian Renewable Energy Agency (ARENA) with existing infrastructure to be repurposed.

[21][22] The facility has the capacity to produce up to 80kg of hydrogen per day by electrolysis of water with a 200kW electrolyser using electricity from a 87kW solar panel, a 100kW battery storage or from the power grid.

[23] The centre will support the newly imported second generation Toyota Mirai released in Australia in April 2021 with an initial allocation of 20 vehicles for organizations and business.

It is also a key partner of the Tamworth Country Music Festival, in addition to being the major sponsor of Planet Ark's National Tree Day.
