@cody hi just sharing my experience since im already living here in Darwin for 7 months.
Rent 250 a week studio type apartment (fully furnish)
350-500 two bedroom apartment depends on location(fully furnish)
ulity bills - i dont watch tv but i have computer that i use everyday plus the appliances like ref, stove etc. about 200 for three months. so every three months ang singilan dito ng bills
water kasama na sa rentals ko un bayad
internet fibre Dodo - 69 amonth but I signed up sa Telstra kahit medyo pricey.
i dont have a car because i rent in cbd and my work place is walking distance.
so malaki na titipid ko sa transpo. once in a while i go to the mall which is sundays but i just ride the bus. 3aud for two ride pag within 3 hours ka sumakay but beyond 3 hours you have to pay again.
the most i spend is for food. i really dont go out as much but maganda naman mag park with friends paminsan minsan. i also indulge to eat outside paminsan minsa mga 15-30 per meal which is not bad; im really on tipid side because i have to save.
so you can do the math on your average consumption.
hope above helps.
