Was just wondering if there are any good suppliers in Australia of taffeta, ripstop nylon, cuben and high loft goose down.

If anyone could let me know of suppliers of any of these items in Aus it would be greatly appreciated.

The short answer is no.

The longer answer is the there are no suppliers that offer a wide range of fabrics and hardware with relatively reliable supply (available year round) and sell in small quantities. You can pick up some bits and pieces from specialised suppliers particularly if you have industry connections. Most of us use the US based suppliers for most MYOG supplies.
