At a time in Sydney when liquor laws are becoming more and more restrictive, late-night venues are shutting their doors and the city's social calendar appears uninspiring to visiting tourists, one event is turning heads as Sydney's wildest, must see attraction.
After just 27 events, Sydney's Yacht Social Club is one of the hottest tickets in town, with every party selling out in less than 24 hours, months in advance.
The boozy, sun-soaked yacht parties take place on Sydney Harbour, complete with DJ's, Barbecues and the backdrop of the city's most famous landmarks.
With more than 200 people from destinations all over the world, the crowd comprises of young, attractive, adventure seekers leaping off boats into the harbour.
"Originally a lot of our crowd was European expats, now more and more Australians have come on board too," event organiser Phil Lee from Have You Heard Events told Xinhua.
"We have had quite a few Asians attending also, but in terms of Chinese tourists coming on board, that is something I would love to investigate and open up to that market because I'm sure they would love it."
"How I do that, I'm not sure, but it's something I'm really focusing on."
The event compiles of eight luxury catamarans being anchored together in what's called a raft-up.
Phil got the idea when on a sailing holiday in Croatia, after leaving his lucrative career as an IT specialist for Microsoft.
"At 28 years old I was living in London and loving London but hating my job, so I thought there has got to be something more to life than this," Lee said.
"So I came to Australia for my brothers wedding and I just never left."
Faced with endless safety and environmental challenges, the party-planners have so far been able to navigate the difficult waters of the tourism industry.
"We have a great relationship with the police, I am completely open with them," he said.
"We have risk assessments, safety management plans, I have two safety boats on standby, I have security personnel, we have lifeguards, qualified skippers and deckhands looking out for everyone's safety."
The group also employs divers and other personnel to clean any rubbish left by revellers.
"Sustainability is really important to us," Lee said.
