For the chart on the ATO's tax rates go to
http://www.ato.gov.au/content.asp?do...uals/12333.htm
0-6000 no tax
6,000-20,000 17%
20,001-50,000 30%
50,001-60,000 42%
60,001+ 47%
plus the medicare levy of 1.5%
Unfortunately when you have a large area and a small population taxes tend to be higher. If Australia only had to deal with an area the size of Sydney then your taxes would be quite a bit lower.
