Not bloody much, mate, if at all. You'll have to keep your day job 'till the logbook gets a little heavier!
Believe the guys in Cairns got paid something (maybe AUS20/hr) but i think the Toogoolawah (can't remember the spelling)guys did it for love.
Don't know about the rest. Let your fingers do the walking and find out first hand. Never know what you'll come up with.
Good Luck!
