Graeme, have a look here. No waiting list for Tweed River for a swing mooring. should cost about $350 a year for the license and about the same for a mooring service each year.

www.msq.qld.gov.au/Waterways/Buoy-moorings.aspx.Four years ago I went through the same process as you are now. The issues I had with a trailer sailer were that I don't have a driveway big enough, and the street is too narrow to have it parked there full time. I also checked out how long it takes to rig and de-rig, and added to driving to the water way made the decision that I would rarely go sailing because it took too long to get ready and get home again.
With a moored boat, whilst you are limited to your local areas for day or weekend sails, you will go more often because it's so easy. Rubber dinghy on the roof of the car, Row out to your boat and go sailing. I live 30 minutes from my boat and can leave home at 9 and be o
Under way at 9.45.
The easier it is to go out on the boat, the more often you will go and the more often you will have more fun and that, in my humble opinion is what it's about.
