Tax is the second most thing that's on our minds and that's particularly so with a federal budget a month away. Prepare for a lot of discussion about GST, personal and company rates of tax. There will also be discussion about whether Australia is a highly taxed country. Here the waters get a bit murky and has sharks circling. New Zealand has a higher GST (20%),other countries have lower company tax etc etc. Politicians, experts and your highly informed mates tend to be selective in their argument.
There is one source of information that compares 'Apples with Apples' - The Treasury. Their report is that pretty much anyway you carve it up, Australian is a lower taxed country.
The next argument is whether that's good in terms of the services we receive - ie we get what we pay for.
