Mate, these kits are rare as hens teeth...
You'll be lucky to find a complete kit, even if you did it would be in pretty average condition I reckon.
If there even was a complete kit somewhere in AU it would be snapped up d*mn quick, probably by a member of this forum.
It will also be quite expensive buying anything from AU at this point in time with our dollar being so strong and yours falling more and more behind.
A final note, check noss's thread in the for sale forums about the TRX kits.
