I am coming down this Friday to help a friend bring a 48ft coastal cruiser back to Cairns.
Top speed is 8.5knots on a calm day, and draws 1.2 metres and has a beam of 4.6m.
From what I've been reading on Cruising the Coral Coast by Alan Lucas, it is possible, but then consulting Beacon to Beacon, and Google Earth, it's kind of turning me off going the shorter route.
My ability is in negotiating reefs and northern mangrove rivers and creeks, and I have no practical experience in bar crossings, perhaps I have just answered my own question?
Any opinions, liability free, are appreciated. I'll post a final comment on Thursday
