On a recent trip, I found our Melbourne forum very quiet, too. Was hoping for some help in exploring the punting options. Turns out, they seem to have another site they favour. Not sure if I am allowed to mention it here.
If you google the Nakedtruth Melbourne, you should find it. You have to post a review before you gain access to the reviews. There was no read-only option, so they are super careful. FWIW
