You can pick up wind surfing gear pretty cheap on gumtree, seen quite a few kits for sale in Australind. Yallingup is very similar to where I'm learning mate, flat water inside an outside table reef with waves out the back. I'm learning on my 666 though, which is 32 inches wide. Makes it heaps easier to learn.
Your bailing to the great southern these school holidays aren't you

Hows the weather looking for down there. I remember you saying you were gonna be doing some driving & this is the worst time of year for surfing up around where you grew up. I hated being up there between June & March, Southerlies every friggin day pretty much. You can usually find a place out of the wind this time of year in the great Southern.
