From tropical Queensland to Tasmania’s Roaring Forties. Go South! 1700 miles sailing alone

1700 miles south, 3000 kilometres. Just one stop, Bundaberg. The trick is to catch the right wind. In the Coral Sea it blows from the front for 10 months as a trade wind. But now, in November, it’s not regular. In the Tasman Sea, from Bundaberg onwards, it can blow from bow or stern. Sometimes it changes directions within hours. And it's almost always strong.
