Greetings everybody, been checking in on this forum for a while and really appreciate it. Posting today to look for some advice, suggestions, critiques, or anything in between

, with regards to moving to Australia and learn how to sail..
I'm 29, male, from the US, with a small amount of sailing experience (2 weeks in British Virgin Islands, a few random classes over the years, and coastal navigation cert). I feel like the only real way to truly learn is by getting miles under your belt. Where I'm located - there's not much sailing and I'd have to move regardless to learn, so I figure - why not move to another country for a bit while I learn.. I'm obsessed with travel and sailing seems one of the best ways to do that, so that's the source of where my passion for this sort of adventure is coming from.
Any advice on best part/city in Australia to be based out of for this sort of scenario? Once in town, what's the best way to go about finding a boat to work on/with? Or is walking the marina acceptable?
