Phil Goard designed and built an aircraft called the Goair Trainer at Bankstown Airport in Sydney during the 1990s.

The first Model J544, known simply as the Brumby after a wild horse was registered under a Recreational Aviation Australia certificate in October 2005 and was publicly demonstrated in April 2006.

Brumby anticipate an updated version of this aircraft will compete with the Cirrus SR22, while the company also announced plans to develop a turboprop powered variant aimed at a niche business market with no established competitors.

[1] A major 40-year deal was signed in 2014 with the Chinese government owned AVIC to produce the Brumby 600 and 610 aircraft in a purpose-built facility in Fujian Province.

The Aircruiser design was not included in the deal, as Brumby intends to utilise the additional capacity at its Cowra facility to focus on development and production of this model[3] In addition to production facilities, the agreement is also reported to include global sales and support, as well as Brumby's participation in the research and development of a new all-composite seaplane intended to carry 10-20 passengers, addressing a gap identified in the Chinese general aviation market.
