No formal rules around Tipping in Australia, but some places of service (cafes, restaurants, etc.) have tip jars as a "donation or gift" rather than the norm.
You work in hospitality, you get a minimum wage, usually $10-$30/hr depending on your position/experience etc. and usually the tips are evenly dispersed to all staff who worked that shift as one customer may tip $20, compared to $2 tips or $0 from other customers. Kinda see it as a end-of-shift bonus if you get $20 worth of tips to take as cash in hand.
It's correct Australian's vote in candidates, which in these circumstances would be great (not only for Assange's case) but more importantly to see greater diversity in our Senate, because the majority right now are Labor/Liberals.
Imagine in 100 years time, they become the major political party, forming government. It could possibly be something entirely different.
Great article, I had to do something similar few years back. Good to see some of the ideas we had were the same. Just wait till you have to mirror the site for Arabic etc. That's when it gets fun.
