I can give you a summary of what's like to stay in Victoria ,
Australia.
You need at least 18K -20K for your rent , food, bills , books on
top of your tuition fees. That is a bare minimum estimate.
Depending on your student visa to survive playing a russian
roulette. You can work at most 20 hrs/week during a school
semester. Most chinese restuarants will employ waiters/waitresses
but they pay bare minimum and sometimes illegally low ( 4-6 dollars
per week).
If you are a nurse, the hospitals will employ you on a casual basis
because they need nurses. Otherwise tough luck getting jobs.
You can opt to study distance in Singapore and complete your final
year in australia.
