Use of the word "association"

[Steve A]

I wish to run a profitable business using a domain name and business name including the word "association", example "www.brisbaneplumbersassociation.com.au".
1.Membership is free to join however there is a cost to use the association logo if so desired by the member.
OR
2. Membership is paid annually. Other optional services/benefits are sometimes free, some paid for.

Question: Can I operate this under an association name as an UNINCORPORATED ASSOCIATION (profit making).
The QLD Office of Fair Trading do not know the answer. The only information I can find is for incorporated associations which have extensive rules and regulations.
I am a sole operator.

Thanks
