Mike Cannon-Brookes rumoured to snap up Sydney penthouse

Mike Cannon-Brookes’ divorce from his wife of 10 years is the subject of fresh rumours after the billionaire reportedly made a new move.

Word from the amp-up local Stanley Street, Darlinghurst coffee shop patrons is that software giant Atlassian billionaire Mike Cannon-Brookes has bought a bachelor pad.

No ordinary one, but reputedly the $15.2m New York warehouse-style penthouse on the top level of nearby Angus House.

It was knocked down to a buyers’ agent at a one bid auction in early March by estate agent Maclay Longhurst who marketed it as a “ultra luxe trophy penthouse.”

The 585 sqm apartment won the Master Builders Association of Best Renovation 2023 which had been commissioned by its vendors, Dr Jonathan Seef and his wife, Rachelle.

They had paid $5.555m for the apartment that has recently been a high-end rental. Alternative dance group Rüfüs Du Sol took the apartment for their Sydney shows.

The four-bedroom apartment occupies the entire top floor of the former head office of Moran Health Care which was redeveloped by developer duo Theo Onisforou and James Packer into 18 apartments in the late 1990s.

The building at the corner of Stanely and Palmer streets was constructed in the 1930s having been a tyre warehouse in its early years

It still has warehouse features, including exposed brickwork, ductwork, and high ceilings.

The penthouse has a gym, sauna, and a bar area with a wine cellar.

A billiard room opens to a private deck, one of two in the apartment. The rooftop deck has a barbecue area and outdoor dining space set in landscaping.

No confirmation of the rumoured buyer has come from Sydney Sotheby’s.

Cannon-Brookes, who split from wife, Annie in mid-2023, enjoys a wealth of $29 billion, according to the recent The List: Australia’s Richest 250 of 2025 by The Australian.

The split came after 10 years of marriage and the pair are currently in the middle of divorce proceedings as they look to split up their considerable assets, which include a real estate portfolio which stretches across Australia and is valued at more than $350m.

Rumours of the Darlinghurst property purchase follow closely on the heels of news that Cannon-Brookes bought a private jet as big as a house.

The Atlassian co-founder bought a Bombardier Global 7500 – the personal jet of choice of Hollywood luvvies including Matt Damon and Mark Wahlberg, reality TV star Kylie Jenner and fellow Aussie rich lister Andrew ‘Twiggy Forrest.

The Bombardier 7500 comes with a price tag of around $120m – even more than the Cannon-Brookes spent when he laid down $100m for his Sydney Harbourside home in 2018.

The tech guru’s new Bombardier is a house in the sky and offers the space and luxuries most Aussies don’t even enjoy in their on-ground residences.

This jet-home features a number of living configurations and boasts a four-zone cabin that can seat up to 19 passengers and sleep eight.

The Global 7500, costs around $15m a year to run – which based on an average of 450 owner-operated hours comes down to about $16,000 to run.

According to Bombardier, the Global 7500 has a range of around 14,300km, which gets it from Sydney to Los Angeles with fuel to spare and has a top cruising speed of 956kmh.
