Well as the resident Australian, and Maton afficianado (OK I only have 2 so far, because they are frikkin expensive) I felt duty bound to pipe up.
Like Eric said, Maton (and Cole Clark) are pretty much the de-facto standard in high end acoustics here in Oz. I mean they've been around longer than Gibson as far as I know so it's no surprise.
The one Slash is playing in Civil War looks like a Maton Tommy Emmanuel Series. It's a pretty high end unit, they retail for like $3800AUD VERY drool worthy.
TE Series
The one Myles is using looks to be a Maton Messiah, VERY high end bit of kit there. You'd be looking at around $4400AUD for that.
Messiah
Also that was done right here in Sydney just recently. Audience were competition winners only I think.
Oh and lastly, if you don't know who Tommy Emanuel is, do yourself a favor and find out. Some consider him one of the worlds best acoustic players and he received honorary degree CGP for "Certified Guitar Player" from Chet Atkins.
And he's Australian.........
