27 for me, but only because I moved jobs to another state.
Only reason I stayed that long and would have stayed longer was so I could save money for house deposit as houses in Australia are not cheap. In Australia it would not suprise me if the average age when people leave home now (in the last 5 years) is around the 25-30 mark. For those who do not care about owning property and are happy to rent all their lives, probably closer to 18-20.
