I used to think it's cheap to live in Philippines, until I did my research when I was figuring out how much I should really charge my clients.
It turns out the cost of living in Manila is relatively expensive compared to the minimum wage and even the average wage that most people get here. Main point: People work too long to be able to buy stuff here. It's saddening, really.
So for Filipinos wondering how much they should charge, and to clients wondering how much they should pay their Filipino freelancers, I would suggest not using the minimum wage and average wage in PH. I even did a calculation about this but I can't link because oDesk told me off before when I did so!
As for Australia, yep, you definitely have expensive stuff! Even more expensive than NZ, eh? But then Aussies' minimum wage/average income is relatively high anyway. So it's all good for you, I think.
