where can I buy IRIX (for sgi machines) in Australia (not from SGI tho)

hi,
ive just bought myself a used SGI Octane system, but it doesnt come with any IRIX media, im wondering if any of you aussies out there know where i can purchase a copy (apart from SGI and Ebay) in australia?

I dont want to have to buy it from SGI as ive heard that their support for older systems and non corporate customers can leave a bit to be desired at times...

if anyone can help me (or if anyone has a FULL cd set of IRIX 6.5 (or newer) cds that they may want to sell, please give me a reply, it would be much appreciated :)
