Mr Money Mustache is a retiree who now writes about how we can all live a frugal yet Badass life of leisure. He retired from real work way back in 2005 in order to start a family. This was achieved not through luck or amazing skill, but simply by living a lifestyle about 50% less expensive than most of his peers and investing the surplus in very boring conservative Vanguard index funds and a rental house or two.
This blog is very, very much worth reading if you want to retire early. Canadian so you need to ignore anything that might have tax or other legal issues in Australia, which is mostly around retirement savings and actual dollar values of anything like cars, houses and the cost of living in general.
