In the immortal words of Kermit the Frog, it’s not easy being Green and no-one knows that better than Mike Cannon-Brookes, the ‘accidental billionaire’ co-founder and co-CEO of software company Atlassian. Cannon-Brookes is reputedly the richest person in Australia under 40 and worth around $13.5 billion. It may sound like a lot of money, but Mike was channeling Motown legends The Temptations’ Ain’t too proud to beg when the company, of which he owns around a third, decided to ask for a handout from the City of Sydney.
