I lived in both Singapore and Sydney, and Singapore is cheaper - food is cheaper in SG - apartments were cheaper in Singapore. Sydney has become expensive - taxes are lower in Singapore - public transport is cheaper in Singapore - alcohol is expensive in both places - My company in Singapore paid medical, but in Australia I had to pay my own medical insurance - In Singapore I got paid all cash but in Australia it's required to contribute to Super which is a horrible system compared to what America got - Expat salaries are higher than in Australia

Singapore has also public housing(HDBs) for locals which are more affordable. Sydney has no affordable housing at all.

I'd say I saved 30-40k more in SG every year.
