Australian retirement rules are very different to US.
We have the Superannuation plan; which was only mandatory since about the mid 80's or so. I guess you could say this is the 401K in US parlance. Employers have to contribute 9.5% of your salary to your superannuation account. I can also do a voluntary contribution to the account to help boost it along. I just can't touch the money until I'm 60. That's still a long way off but I'm not sure I can last till then!
So, I'm hoping to save enough money in the next 3 - 5 years to allow me to stop work and sustain me until I can access my super money. It'll mean much less vacation but I guess I can deal with it.
