Shipping, Aust Post has a booklet or go to there web site for freight.
If you send each wheel (apprx 10-12Kg Alloy) its around Melb- Sydney $14 Adelaide same Brissie $18-20 with $100 auto Insurance per box.
They have max weight 20Kg and its not realistic to stash 2 in one box to save packing.
Grab some olf boxes from Bob or Beaure or Bridgestone.
With a wheel & tyre Aust Post won't send as weight versus size is too big, go for a courier and the price is real scary. If anyone knows a courier who'll do real cheap Interstae let me know.
Murray Valley Freight not bad though.
