Depends on your expectations! You don't say if you are on your own or with partner, children etc. Rent of a good 2 bedroom apartment from about $300 per month; running costs probably around another $100. Fuel is reasonable - to fill an average car costs about $20; Food is cheap - you can eat at hawker stalls for about $10. Plenty going on if you want to join things. I would guess for a single person with average requirements you probably need around $800 per month. I am sure that you can do it cheaper and I know that you can do it a lot more expensive!
