While MTAA Super is the national industry-based superannuation fund for the motor trades and allied industries, anyone can join, including self-employed people, spouses and the general public.

MTAA is the peak national representative organisation for the retail, service and repair sector of the Australian automotive industry. The Association represents the interests, at the national level, of over 100,000 retail motor trade businesses with a combined turnover of over $120 billion and which employ over 316,000 people. MTAA is therefore the largest 'stand-alone' small business association in Australia. The Association is a federation of the various state and territory motor trades associations as well as the New South Wales based Service Station Association Ltd (SSA) and the Australian Automotive Dealers Association.
