Stars frock up for exclusive party at Justin Hemmes’ harbourside mansion

Justin Hemmes’ very pregnant girlfriend stole the show at an exclusive party held at his Sydney mansion last night.

A slew of Aussie celebs – and one US Top Model who now calls Australia home – flocked to an exclusive venue in Sydney’s eastern suburbs last night for the Silver Party charity bash.

The event, a fundraiser for the Sydney Children’s Hospital Foundation, returned to the Sydney social scene after a three-year hiatus, and took place once more at the Vaucluse home of Merivale mogul Justin Hemmes, The Hemitage.

More than 300 guests gathered on the harbour foreshore for the bash, which had a “rock royalty” theme.

Check out some red carpet arrivals below …

The historic Hermitage house was built in 1831, and Hemmes lived in the house with his family when he was growing up.

He later moved back in as an adult, spending several years fully renovating the waterfront property.

He told Vogue in 2015 that there had always been a very “communal, social feeling at the house” when he was growing up that he was keen to retain in the renovation.

The Hemmes family have a net worth of A$1.46b billion, according to the 2024 Rich List, with Hemmes now owning around 80 pubs and restaurants in Sydney and across NSW.
