^ they're the kinda pale pinkish ones all over Brissie (and other places I'm sure, but that's where I've seen them), and yeah they bark...sorta a weird clicking sound
Cool find!
Definately a Gehyra of some sp, Asian House Geckos have small bumps along their tail, and usually a bit more slender in build.
Years back i found a Marbled Gecko in my backyard that had three tails in one, unfortunately no decent photograph.
