There are several Aus-published authors on the forum, as far as I know. I've had non-fic published by Allen & Unwin.
Congrats. I guess I ask because from what I've read, getting published in the US and elsewhere seems to involve acquiring an agent and whatnot... however if you want to be published in Australia it seems like you generally just submit directly to the publisher and take your chances.
I'm working on an Australian 'Lock, Stock and Two Smoking Barrels' essentially, so I wish to target Australian publishers... I can't see the yanks or anyone else being that interested in it.
