Howdy Ian.
Unfortunately there are no hire places on the goldcoast (or even in Brisbane that I know of). If you don't bring your own gear you will be stuck. If you are prepared to buy gear, Surf FX on goldcoast (ferry road) will help you out. Talk to Ian on 07 5531 3199
There is a caravan park right on the broadwater (the broadwater caravan park) which also has cabins available but I think there are only four cabins. You can see them in the background of the photo here
acecwindsurfing.tripod.com/Photo_Gallery_5_5_2004/pages/IMG_0917.htm There are also many highrise appartments around the broadwater like "the Rays resort". I personally don't know much about accomodation pricing around the place (hopefully someone else will), but it would be highly overpriced as everything is on the goldy.
Wind conditions should be on the improve from here on - nice 15-25kt northerlies around september. we tend to get some good but chilly winter southerlies about now
some photos of flat water sailing on the broadwater to wett your appetite
