OKA Australia is a Western Australian based 4wd manufacturer mainly supplying 4wdtour buses and trucks. OKA is based in Bibra Lake, where all OKAs are made.OKA's current holding company is Reymer Pty Ltd. Less than 500 OKAs have been built.
OKA started in 1986 when a group of Australian mine executives discussed that each of them needed an off-road truck with a three ton payload and nothing on the market at the time filled those requirements. Those executives formed a consortium and the OKA brand was born.
Having agreed on the blueprints, the group undertook a comprehensive market study covering over 1,200 mining companies, government departments, farmers, the Australian military and potential private users to establish the parameters for the design.In 1987, work on the first prototype began and in 1988, it underwent its first test. Prototypes continued to be produced even during production up until 1992.
Soon after, the first production model, the 'XT', entered production. It was followed by the 'LT' which was also followed by the current model, the 'NT'. These vehicles have been supplied to government departments, tour bus operators, private industries, mining industries, the military and recreational companies and are currently being sold in Papua New Guinea and Africa (as well as Australia) and are being developed for the UAE, and Europe.
OKA has made and sold 2 models (the 'XT' and 'LT') and is currently making and selling another (the 'NT'). The models are sold in various body shapes including Cab Chassis, Single Cab, Dual Cab, Multi Cab and Tourbuses.
