Insta-fitness demigod Kayla Itsines has been utterly dominating a niche which, in all fairness, she pioneered. Her ridic business acumen has even landed her a spot on BRW’s annual Young Rich List, and Itsines boasts a well-earned fortune of $46 million.
As the name suggests, there’s a crazy amount of money on that list, but the cumulative figure of the top ten highest earners under 40 years of age is genuinely stupefying. If you were to tally the fortunes of that mob, you’d have a total of $7.53 billion.

Well, that’s not entirely true. You’d have $7.534 billion, but that figure is so large, it’s easier to just round down by $40,000. Stunningly, the majority of that sum comes from Mike Cannon-Brookes and Scott Farquhar of Atlassian fame. Their tech juggernaut has amassed ’em a fortune of $4.6 billion alone.
