If you do move to Singapore and did get a car, do all your shopping and buy petrol in Malaysia.
If you want a bit more of an adventure and potential to have a big salary and lower cost of living then go to Bangkok or Jakarta or Manila or a smaller city like Phnom Penh, Saigon.
Phnom Pen definitely qualifies as "a bit more of an adventure" in comparison to Singapore that is for sure!!
If you are a fan of bribery, corruption, kickbacks and that kind of thing it would be perfect. If you like rules and orderly society, not so much. The Happy Pizza is good though..
