Go for a J1 visa and do your CPL in the states then work as a flying instructor until you build up 1000 hours or so then take your pick of OZ or UK. You would be more employable with those hours rather than just a bare CPL.
Plan 2. Come over here and train with PHS or Chopperline as they both have avenues for newly qualified CPLh's to get work and build experience. (I would choose Chopperline)
The market here is really good at the moment and if you're prepared to travel up north and knock on a few doors you will get a job.
The down side of OZ is the crap pay you will receive as a new pilot and it wont get much better until you crack about 1000hours or so.
Anyway a couple of ideas for you mate and good luck with it
