I'm just giving you a rough estimate, because the costs in
Melbourne and Sydney differ from Perth, where I've a bit more
knowledge, though I've not been back for two years.
It depends on different sectors. Taken at absolute value,similar
property is slightly cheaper, same for transportation e.g vehicle
ownership.
However, your income tax is higher, but this reduction in monthly
disposable income is made up by a longer-term investment for any
time you get old or destitute.
Fair go. It's a concept that many Singaporeans don't understand, or
think they are too superior to grasp.
