Michael Cannon-Brookes (born 17 November 1979) is an Australian businessman who is the co-founder and chief executive officer of the software company Atlassian.

Since 2018, he has been involved in the Australia-Asia Power Link, a huge electricity infrastructure project to be developed in the Northern Territory by Sun Cable in a collaboration with the Australian businessman Twiggy Forrest.

[3][5] He attended Cranbrook School in Sydney,[6] and graduated from the University of New South Wales[7] with a bachelor's degree in information systems on a UNSW co-op scholarship.

[10] They have said they founded Atlassian with the aim of earning the then-typical graduate starting salary of A$48,000 at the big corporations without having to work for someone else.

[13] They decided to forgo the expense of hiring sales people, and instead spent their time and money on building a good product and selling it at a more affordable price via the Atlassian website.

[27] In October 2021, he pledged to donate and invest $1.5 billion on climate projects by 2030 to reinforce the COP26 goal of limiting global warming to 1.5 degrees above pre-industrial levels.

[33][34] In March 2022, Cannon-Brookes and the billionaire Andrew Forrest invested in the Sun Cable project, to build a solar and battery farm 12,000 hectares (120 km2) in size at Powell Creek, Northern Territory, and a power-cable to link it to Singapore (via Indonesia) leaving Australia at Murrumujuk beach.

[37][38] In December 2020, Cannon-Brookes bought a minority stake in NBA team Utah Jazz, along with Qualtrics co-founder Ryan Smith.

Cannon-Brookes also acquired the 1923-built heritage residence Verona, designed by architect Leslie Wilkinson and located in Double Bay, for A$17 million.

Prior to that, in 2016, Cannon-Brookes had bought the A$7.05 million SeaDragon house, built in 1936, also designed by Wilkinson and updated by architect Luigi Rosselli.
