Singapore is expensive to put a roof over your head and cars. My car here in Oz cost me 35k new, the same in Singas would probaly be 5 times that. I guess one good thing coming from Australia and US is we get 30% more for our dollar.
Even if you get into Tiger and Singapore is not really for you, well you could always try and sort out your CASA issues whilst with TR and try and get a transfer into Australia once you have been there for a year or two. 205k for capt in Singapore is not that bad compared to 185k in Aus with obscene tax rates.
