The who’s who at billionaire Anthony Pratt’s Raheen mansion

Police and private security blocked off a lane of Studley Park Road to ensure guests could arrive. There were two entrances: a side entry for the extra important VIPs who could avoid the cameras, and the front door for everyone else. A group of young Perry fans waited outside, trying to film her as she performed.

Albanese appeared at the corporate soiree in Melbourne the night after he watched Taylor Swift from VIP seats at her first Sydney concert, sparking some Coalition criticisms that the prime minister was prioritising big-name events over the cost of living.

“We warned Australians that electing Anthony Albanese could deliver a socialist Prime Minister, but none of us expected that we would get a socialite Prime Minister,” Deputy Opposition Leader Sussan Ley said.

Ley also knows her way around a social event. In January 2017, it was revealed she travelled twice to the Gold Coast at taxpayer expense for New Year celebrations in 2013 and 2014 hosted by a multimillionaire political donor and recruitment chief Sarina Russo, but argued she attended to discuss the government’s agenda.

Heloise Pratt was there at Raheen on Saturday night, but her partner Jon Stevens was absent due to work. A third Pratt sibling, Fiona Geminder, attended with her husband Raphael Geminder, and their daughters Georgia, Bella and Sammy, along with Georgia’s husband Matthew Danos.

Jeanne Pratt made an appearance, along with Heloise Pratt’s son Jake Waislitz and his partner Ava Fried.

Federal Energy Minister Chris Bowen was in the crowd along with cabinet colleague Attorney-General Mark Dreyfus, as was former University of Melbourne chancellor Allan Myers, businessman Sir Rod Eddington, ANZ bank chief Shayne Elliott, investor Ashok Jacob, former Woodside and NAB chairman Michael Chaney, former Woolworths boss Roger Corbett and fast food billionaire Jack Cowin.

US ambassador Caroline Kennedy also attended, before flying back to Canberra on Sunday morning to attend a Bunnings sausage sizzle to promote the Shitbox Rally cancer fundraiser, in which she will take part.

Music promoter Paul Dainty and his wife Donna Dainty came along, as did Penny Fowler, who is an executive at News Corp and Rupert Murdoch’s niece.
