Justin Hemmes throws WILD staff party at his Sydney club The Ivy with girlfriend Madeline Holtznagel

Billionaire pub baron Justin Hemmes certainly knows how to throw a party. 

The 49-year-old Merivale CEO splashed out $1million to throw a wild rave for his 4500 staff members at his popular Sydney CBD nightclub The Ivy over the weekend. 

Hemmes shared several videos from the epic bash, aptly named ‘Ivy Land’, on Monday, with his model girlfriend Madeline Holtznagel, 26, taking centre stage as she danced in a glitzy rhinestone bra to the pumping DJ beats.

Her model sister Simone, who recently appeared on SAS Australia, later shared a video of Madeline hosing down revellers with a steam machine as she danced onstage.

The crowd danced to a banging setlist of club anthems, with the majority wearing colourful outfits and props as they fist-pumped to the beat.

One employee even had Hemmes’ face emblazoned on a poster, which was stuck to an umbrella and raised in the air in honour of the CEO.

Hemmes made his debut on the Financial Review Rich List in 2018 with an estimated net worth of $951million.

Last year, his net worth grew to $1.2billion, making him the 97th richest person in Australia.

The billionaire businessman owns a string of lucrative pubs and establishments across the country, including the Lorne Hotel on Victoria’s Great Ocean Road, along with The Quarterdeck, The Inlet and The Whale Inn.

Huge parties for staff have become folklore at Merivale, which is currently facing a class action before the Federal Court for underpayment of workers. Merivale has denied liability and is vigorously fighting the class action. 

Madeline and Justin have been dating for some time, and she even spent lockdown at his Vaucluse mansion in 2020.

She now reportedly lives in a Coogee penthouse he owns.
