Didn't take long to get off topic....
The original poster seems to be Australia based, so probably Police Aviation Services is not the company he refers to. A quick visit to the Petroleum Air Services website does not show any vacancies. I'm guessing he's seen an advert by PAS Aviation Services, who are a recruitment company. A quick look at their site shows several rotary vacancies - in SE Asia.
Anyway, back to the debate on FAA vs JAA...................
