Australian tech billionaire Mike Cannon-Brookes splits from wife

An Australian tech billionaire worth $19 billion has reportedly split from his wife after 13 years of marriage.

Australian tech billionaire Mike Cannon-Brookes has reportedly split from his wife after 13 years of marriage.

Sources close to the family of Mr Cannon-Brookes, who is Australia’s sixth-richest person and the co-founder of Atlassian, have confirmed he is separating from his wife, Annie, according to Nine newspapers.

The couple married in 2010.

Mike and Annie Cannon-Brookes have reportedly split.

Their separation comes just a week after the high-profile split of Australia’s richest couple, Twiggy and Nicola Forrest.

The Forrests, who had been married for 31 years, said they were living apart but insisted the separation will not impact their mining and philanthropy empire.

Mr Cannon-Brookes made his estimated $19 billion fortune alongside fellow Aussie billionaire Scott Farquhar, with whom he co-founded software firm Atlassian in 2002.

The company is widely considered a great Australian success story, its share price having quintupled since it was listed on the US stock exchange in 2015.

Atlassian has, however, suffered a tough 12 months amid broader turmoil in the tech sector. In March, the company laid off 500 workers just a few months after a dramatic hiring blitz.

In a self-described “no bulls**t” note to staff, Mr Cannon-Brookes and Mr Farquhar said it was a “very hard day in our 20 year history” and they were “deeply sorry” to make the job cuts.

“To be clear, this decision is not a reflection of Atlassian’s own financial performance, as we will be reinvesting in roles that better support our priorities,” they wrote.

The Cannon-Brookes family owns an impressive property portfolio, including the 1.1-hectare Fairwater estate, previously the home of the late Lady Mary Fairfax, which they acquired in 2018 for a reported $100 million. It was believed to be the priciest property sale in Australian history.

In June, the couple forked out $14.25 million to buy a home in Newport, on Sydney’s northern beaches, neighbouring the $24.5 million estate they purchased in 2020.

The five-bedroom home is set on a 3000-square-metre block of land and features a 1000-square-metre netted bathing area.

Cannon-Brookes, who was previously a fashion designer, was born in the US.

It’s believed he and Annie met at a Qantas lounge during a trip between Sydney and San Francisco.
