I will recomend a great buissiness to get Fibreglass supplies (resins, hardener, fillers, etc) from in Bendigo (central Victoria). They don't seem to mind giving out info about fibreglassing techniques and/or products either:
Gel-TekFibreglass Products and Repairs
872 Bendigo-Maryborough Rd, Lockwood, VIC, 3551
No webpage but they are in the yellow pages.
Another shop for Falshaw (and other) wheels and bearings. Can't say too much other than they take my money and get the job done:
Bendigo Bearings (Aust) P/L30-34 Abel St, Bendigo, VIC, 3550
Again, no webpage but they are in the yellow pages.
Abbott Supply are a good, accessible place in Bendigo to get steel, engineering supplies and good quality tools.

Fitz'ies Home Hardware. I don't get much from them but they
have stocked sheets of 6mm 5 ply which I have used in my miniyacht seats with success. They are a Home hardware outlet so you might have as much luck at other home stores.

Except for masts, rigging and sails you can get everything you need to build landyachts from the three above stores in Bendigo. Have Fun!!
