Yes there is OBS, either Pulau Ubin or Lumut. Dunno the Tsunami will change plans or not.
As far as I know, your license will not be recognised and you'll still do all the papers in Singapore Flying College. The Civil Aviation Authority of Singapore only recignises licenses if you got it in Jandakot (which is where Singapore Flying College is) or another university in New Zealand (Can't be bothered to find out)
You'll still do the cadetship like any new entrants w/o any flying experience. ie you'll be treated like Ab initio. only advantage is that you'l probably complete Jandakot phase faster than others
Check with CAAS for more info, can't really provide much
