If you are cruising the Qld coast and plan to leave your boat for a period of time (to go back home etc), I can strongly recommend the Magnetic Island Marina. This is a modern marina with floating pens, good facilities, good security and as cyclone proof as it is possible, all at a reasonable price.
We have left our boat there over the summer months and will do so again next summer when we again head back home to Albany, WA. The staff are friendly and helpful, while keeping an eye on the boat while we were away. The shopping and cafe/restaurant facilities are very close by when you are back on the boat.
