Be prepared to cut your little extra lines that come after a big punchline and move on to the next joke or routine to give your set more punch and crispness. You can keep them in your set, but if the audience applauds your big line, don't do your tag when it dies down, just move on.
Moving to Australia was not a career move, but a quality of life issue. It has no guns, no God, and no gangster rap. As an Ethiopian cab driver said to me the other day when I was returning from a gig in Sydney, Australia is a peaceful, democratic place. I like the relatively stress free lifestyle. It's worth the drop in income.
