Designer dresses, Champagne and a $21m mansion: Inside Australia’s richest socialites Deborah Symonds and Lou O’Neil luxury girls’ getaway – and feuding Dina Broadhurst and Kristin Fisher are NOT invited

The who’s who of the Australian social scene gathered for a lavish girls’ outing last week, but two feuding socialites were noticeably absent.

A group of mega-wealthy socialites flocked to Queensland to stay at the $21 million Domic mansion in Noosa, with athleisure entrepreneur Deborah Symonds O’Neil and her sister-in-law Lou O’Neil leading the arrivals.

Deborah and Lou are married to brothers Ned and Jake O’Neil respectively – the sons of millionaire superyacht broker and Rose Bay marina owner Denis O’Neil.

Joining the pair for the lavish trip were famed Pilates queen Bernadette Fahey, PR guru Montarna Pitt, horse racing heiress Kate Waterhouse, Nova radio star Michael ‘Wippa’ Wipli’s wife Lisa, and property empire owner Barbara Coombes.

Instagram photos from the trip, organized by an influencer marketing company, show the women exploring the six-bedroom beachfront mansion dressed in designer dresses and diamond jewelry.

They also spent time posing for photos around the infinity pool, drinking French champagne, eating caviar and playing a game of snooker – all while admiring the panoramic views of Sunshine Beach.

Other features of the house include a steam room, sauna, ice bath, commercial cinema, gym and personal concierge service.

As the evening progressed, the ladies were treated to dinner prepared in their home by a private chef.

However, there were two notable absences from the guest list: “feudal” socialites Kristin Fisher and Dina Broadhurst.

Although Kristin is good friends with Lou and Dina is a good friend of Bernadette, it appears the pair were unable to secure an invite to the exclusive performance.

Kristin, who owns a popular Eyebrow bar in Double Bay, used to be as thick as thieves with fellow headline magnet Dina – known as the ‘nude artist’ because her artwork often features her naked body front and centre.

However, they have reportedly been shutting each other out – and it is rumored that the reason for their split stems from Broadhurst, 45, and Fisher, 39, ‘both hooking up with the same man’.

“It didn’t end well,” a source said The Sunday Telegraph of their argument on Sunday.

‘They were both single, so at one point they dated a lot. But they haven’t spoken in months,” the insider added.

Ny Breaking Australia has contacted Broadhurst and Fisher for comment.

It comes after Broadhurst appeared to confirm her romance with multi-millionaire kitchen appliance heir John ‘Herman’ Winning early last month.

She reportedly started dating the fourth-generation CEO and heir of Winning Appliances about two months ago, after knowing him for a while.

She seemingly confirmed her romance with Winning in April when they attended a rave together in Pioneertown, California.

Broadhurst took to Instagram to share a gallery of photos from their trip to the United States with a group of friends.

Winning, whose family is reportedly worth $700 million, was tellingly featured in a photo showing him from behind staring out at the desert.

Ny Breaking Australia is not suggesting Mr Winning is the man at the center of Fisher and Broadhurst’s alleged feud.

Earlier this year, Fisher finalized a settlement to deal with her financial problems.

Creditors of her eponymous Double Bay salon, including the ATO, will now receive between six and nine cents for every dollar they owe.

The deal saw Fisher reduce her tax bill to less than $100,000, which is less than half of what she had previously offered to the ATO in a previously rejected compromise payment.

She toasted the financial victory with a $600 bottle of 2008 Dom Perignon champagne and a bowl of small fries.

Fisher had previously offered to pay the ATO $200,000 over two years in a restructuring plan drawn up by its former administrators in July, but that was rejected by the ATO.
