Apologies for not replying sooner. Still trying to source Australian made fabrics and as soon as I do I shall let you know. There are some Australian aborigine type prints available but they vary between $21 to $25 Aust per metre. So very expensive. Sometimes they can be cheaper but then sometimes the quality is not as good.
I do purchase fabric from USA mainly from Hancocks, Z & S Fabrics and Shabby Fabrics. The exchange rate is quite good at present so even with postage etc it is still cheaper than buying fabric in Australia!
