Many Thanks for the replies Gents!
@Ross, I didn't realise that CATIA was used within the auto industry over here, although I did know that things for the industry had taken a turn for the worse recently so I was told to concentrate on other areas.
I had a look at Cornell Design and sent my CV to them today, so will see if anything happens... Sounds a great place.
I did work with a ex-Dassault Systemes instructor who did me a favour and used his contacts to request some info about work over here, but came back with nothing.
@Alex, I have applied for a few Defence jobs, but they seem to require either security clearance, Australian citizenship or ask you to work elsewhere within Australia, which with a small child isn't really an option at the moment, but I will certainly keep my eye on that site, cheers :-)
Thanks again guys for your help, I'll keep you updated
