Business is booming for billionaire pub baron Justin Hemmes and the Merivale tycoon treated his hard-working staff members to the party of the year on Monday night.
Hemmes, who is estimated to be worth $1.06billion, threw a raucous rave at his Sydney CBD club The Ivy to celebrate a successful 2022.
Dressed in a silver boiler suit for the space-themed bash, the 50-year-old was joined by his stunning model girlfriend Madeline Holtznagel, 26.

The blonde bombshell took centre stage in a racy $ 1,390.00 hologram sequin cross over jumpsuit as she danced alongside other scantily-clad partygoers, including a topless woman wearing pasties and man in silver latex mini shorts.
Madeline’s futuristic outfit was completed with rose-tinted sunglasses, giant heart earrings and a Prada cross-body bag.
Meanwhile Hemmes wore a silver spacesuit with a wolf motif on the back and also covered his eyes with giant mirrored sunglasses.

Justin returned to the stage later in the evening to thank his staff for the ‘best year of his life’.
‘I am so grateful to you all and I want you to have the best night tonight. Look around, this is electric, it is magic, and it is all because of you guys. So thank you for the best year of my life and here is to a better year ahead!’ he said to rousing applause.
While it’s not known exactly how long they’ve been dating, Justin and Madeline have been publicly together for about three years.
Madeline previously hinted they’d known each other for much longer.
Speaking to The Sydney Morning Herald in October 2020, she said they had actually met two years before reports emerged of their relationship.
‘We have known each other for two years and met when I was modelling in Singapore,’ she said at the time.
