There are thousands of people who would want to see Amon Amarth in Australia..myself included. This year we've had (or have upcoming) tours from Pungent Stench, Argument Soul (Japan), Angra, Insision, Dismember and Hate Eternal. Not to mention bigger names like Nile, Children Of Bodom, Nightwish, Motorhead, Motley Crue, Fozzy Anthrax and Megadeth.
I think an east-cost tour (Brisbane, Sydney and Melbourne) would be well worthwhile and a pretty safe bet.
I live in hope.
