Australian billionaires are well known for investing. While some have inherited their fortunes, others have founded and scaled huge businesses from the ground up. What they all have in common is that they all rely on strategic investing to multiply and protect their assets.
Some invest in safe-haven stocks and assets, while others are willing to take on more risk in the hope of hitting the jackpot.
The Australian recently compiled a list of 10 Australian billionaires, and the stocks they like to invest their money into.
