Hi OldBoy
Congrats on making that decision, I'm sure you won't regret it. That part of the coast is a dream. For Solo sailing its also really good, there are anchorages about every 70miles or less and some good bolt holes for bad weather. There are plenty of places for fuel, water and provisions. I would take a couple of crab traps along as its a god source of free food until about Island Head point. I see many people with 40ft+ boats and then a tiny inflatable with a 2hp outboard. This I don't understand. A decent RIB with a 15hp is the best way to go in my opinion. There are some many rivers, lagoons etc to explore if you have a good "car" to get around in.
There were only two places in-between Brisbane and Bowen that my charts were wrong. In all cases, believe the physical markers over the electronic or print charts.
In many "larger" anchorages there is a "local" or two. Its worth a few beers to head over and make yourself known, these guys know every trick, every buried log, the good walking tracks, waterfalls and weather patterns.
A spare anchor for sure, navionics on your phone and or iPad as a back up to the chart plotter.
From about June to October the wind is "generally" in your favour heading north. Careful around the whitsundays and some other islands, wind can change 180 in a second.
The first year I sailed Brisbane - Whitsundays - Brisbane over a 6 months period. It was my first boat(S&S36) and I had no sailing experience. There was a steep learning curve but nothing crazy. Sort of easier than I was expecting. Here's a blog I did about that first season:
learningbydoing.exposure.co2016 I did the same route but very differently, more longer 2-3 days legs then longer stops at the places I knew were good. Plus I left the boat in Bowen. Here you can see some videos about this season:
Enjoy!
