Cost of living in Australia

How much money would one need to get settled in Australia and not worry about anything for 2 months?

Friends in Australia would be a great thing to have, but at the time I wrote this article I wasn't that well connected so I just googled variations of the following words: australia/melbourne/sydney living costs/cost of living. And I'm resume what I found to be relevant.

According to Taylor's College (last updated in Nov 2006) the Total monthly rounded costs are:
Melbourne: 1700 AUD; Sydney: 2000 AUD

According to Australian Catholic University (last updated in May 2009) the Total monthly rounded costs are:
Melbourne: 1300 AUD; Sydney: 1400 AUD


I will consider the money objective accomplished when I have 1700*2 = 3400 AUD spare money. That's around 2050 euros.

These would add to the other costs (plane ticket, visa costs, exams that I'll have to take etc.)
