An online course has changed the way basketball star and young rich lister Andrew Bogut thinks about investment.

Bogut began his stellar career in the National Basketball Association with the Milwaukee Bucks where he was the 2005 first overall draft pick but says "early on in my career I had no idea about money".

"I got drafted as a 20-year-old kid and signed a multimillion-dollar contract but had no idea what to do with it," Bogut says.

Bogut, who is estimated to have a personal wealth of $101 million by the Australian Financial Review's Young Rich List, started out with a financial manager who was "pretty conservative" in his management of Bogut's finances and encouraged him to invest in a house and car and then leave the rest.
