Is a sole $65,000 post-tax income enough for a frugal couple to live on in (Greater Western) Sydney, Australia? Budget included.

I come from a traditional background. I'm living with my family and seeking to eventually move out when married. I'd like to get feedback on a budget I've made. Are the figures realistic? Is there anything missing? I've placed an asterisk* on those I reckon may possible be a bit high.

Assuming $85,000 pre-tax, which would be $65,000 post tax. The following are for two people.
