In 1964, the Formula Tasman championship was established in Australia and New Zealand, which allowed the use of Formula 1 cars that could no longer be used due to changes in regulations.
In the first season Brabham, using a specific variant of the BT7 from Formula 1, managed to finish second with three wins and a podium and this prompted Jack Brabham to continue his commitment to the new category.
A new version of the BT11 was therefore developed for the 1965 season. The car equipped a Coventry Climax FWMV V8 1.5 16V engine with 200 hp managed by a five-speed Hewland manual transmission and combined to the rear-wheel drive.

Driven by several drivers including Jack Brabham himself, the car did not prove to be very competitive, managing to finish the championship in 3rd position with a victory and two-second places.
The technical scheme
In 1966 the 5th place finish was an even more disappointing result, enough to induce the British team to withdraw the car at the end of the season and to replace it with the new BT22.
