No. You can't add australium attribute to the items on the right side. But you can easily search for them: http://www.tf2outpost.com/search/208443243

I'm not sure I understand the response. Could you please clarify...

In essence, original question is "Will there ever be an option to create a listing that says I'm looking for an Australium Item"?

Australiums are often overpriced and sellers refuse constantly reasonable offers. It's so bad that I have totally given up trying to pay a reasonable price for one and wanted to just create a listing saying what I'm willing to pay so sellers can come find me when they get real about their sale price.

EXAMPLE: At this very moment there are over 100 Australium Sniper rifles on Outpost. Every seller thinks their rifles are worth 3+ buds and I haven't seen many selling for that price.

Giving us this option will allow sellers to search out potential buyers of their Australiums as well as save buyers a lot of time from offering on a ton of trades only to be rejected repeatedly. I hope it can be added someday.

Thanks...

For now searching for a buyer of AUS weapons you just need to add aus gold paint attrib as that is the most commonly method used by buyers.
