A young entrepreneur behind popular Sydney chain Get Sashimi has bought a five-bedroom Vaucluse mansion for $12.5m.
The home at 36 Derby St sold via Raine and Horne Double Bay’s Richard Faludi and Nicholas Malouf on August 5 and had been incredibly popular with buyers.
The agents have remained tightlipped about the identity of the purchaser, but the recent settlement revealed it to be Antonio Muollo, the 27-year-old founder of the fish franchise that has stores in Bondi, Coogee and Sydney Fish Market.
Muollo is the next generation of the De Costi seafood business, who has been working at his father’s fish shop since the age of nine.

Muollo’s first business, GetFish, was a hit during Covid.
He’s snapped up this luxurious mansion in Vaucluse for $12.5m.
It has panoramic views of the harbour, Bridge, Opera House and city skyline from both levels.
At the age of 19 in 2018 he started Get Fish, an online shop that delivers fresh fish. It was one of the fastest growing businesses over Covid.
Easy to see why Muollo was attracted to the Derby St property.
The marketing advises: “Chef’s will delight in the Calacatta marble kitchen with Miele gas appliances, while a striking open-plan living/dining domain is framed by walls of glass taking in the ever-changing vista, while extending to an expansive view-swept entertainers’ terrace.”
At the time of its listing, Faludi said the property was “bucking the trend” in the slow market, attracting 47 buyers to its first few open homes.

Open-plan living areas lead to an entertainer’s deck.
He said the fact that it was winter and the market had the post-Budget blues meant there’s “not much out there”.
“Where else can you find a house in Vaucluse with five bedrooms with a view?” he said.
The home “commanded one of Sydney’s most extraordinary harbour panoramas”, with uninterrupted views spanning the Harbour Bridge, Opera House and city skyline from both levels.
The back yard features a heated swimming pool amid private established landscaped gardens.
