If you were tasked to set up a financial plan, from scratch, for an Australian resident about to turn 18, in the current environment, what would be an optimized set up? I'm thinking along the lines of putting all savings into a Vanguard ETF while a student at uni, pay cash only for a personal vehicle. In the future, set up a trust to buy a PPOR. Invest every spare dollar earned from part time job, start side business, educate about finances now, caution about consumer debt. What do you wish your (hypothetical) long lost wise old aunt could have advised you, back when you were a nipper? Apart from the obvious, avoid alcohol and toxic mates!
