The Taipan National Association is affiliated with the AYF (now called Yachting Australia). This required providing them with our constitution, contact details for the President and Secretary and an annual fee of $80 (I think). I don't believe there is a requirement to have separate state associations.
We also are formally incorporated as an Association in NSW, which gives some legal protection to the office bearers.
I can provide a copy of the taipan constitution as a starting point.
According to NSW government regulations to set-up any association requires a meeting of at least 5 people, where the rules (ie the constitution) of the association are agreed, a person is nominated to act as Public Officer to apply to the Dept. of Fair Trading to register the Association, and a minimum of 2 people are elected as committee members. The Incorporation fee is about $120 from memory. That's it.
The initial meeting to convene the taipan Association was done by phone hook up involving a representative from each state and AHPC, the designer/manufacturer.
