An inexhaustible source of adventure, Australia is the quintessential superyacht destination. Overflowing with iconic destinations that bask in the country’s infectious laid-back style, it is no wonder Australia is an enduring favourite for sport, adventure and natural wonders.

 With an eclectic mix of unique experiences, there are memories to be made in Australia that simply cannot be found anywhere else. Escape to a country that in one moment will leave you in awe at its untouched natural beauty, and the next throw you into the very heart of the some of the world’s most exhilarating events. Beaches are more than a spectacular blend of sand and sea in this colourful country; they’re a lifestyle and inhabit every piece of Australia’s coastal character, from the boho fashion of the locals to the delicious seafood cuisine served in waterfront restaurants.

Australia boasts an all-year-round cruising calendar, outstanding tourism experiences and world-renowned refit and maintenance facilities that welcome the global superyacht fleet. For those willing to indulge their inner hedonist, Australia is the ultimate superyacht playground.

Unique experiences, all-year-round

Summer and Winter cruising seasons afford Australia an irresistible outdoor spirit that lasts 365 days a year – rather fortunate given the abundance of experiences that await…

A country surrounded by water, Australia is a superyacht haven. Ranging from unspoilt, secluded stretches of glowing white sands to towel-strewn golden paradises and rough surfing havens, beach-lovers will never be disappointed here. Diversity reigns supreme in this huge island nation, where a cruising itinerary can encompass an amazing range of sights not found anywhere else in the world.

From the stunning coral reefs of Queensland, to the spectacular waterways of New South Wales and the crocodile-filled waterholes of the Northern Territory, Australia is a truly unique yachting experience. The kaleidoscopic colours of the Great Barrier Reef are the pinnacle of any diver’s fantasy. From Port Douglas down to Bundaberg stretches 300,000 square kilometres of coral cays, brimming with marine treasures and exquisite sea life. There is simply no better destination for water-based activities.

Not all of the adventure is concentrated at sea. Step inland and discover Australia’s diverse flora and fauna, along with a rich Aboriginal culture. Stop off to play with kangaroos, koalas and wombats or sample fine wines at one of Australia’s exemplary vineyards. The rugged beauty of The Kimberley and Tropical North Queensland presents the opportunity to learn something new. Immerse yourself in 50,000-year-old Aboriginal rock art, brush up on your bush tucker skills or get an awe-inspiring perspective of it all from the sky.

For those who can’t stay too long away from the hustle and bustle of a city, world-class marina facilities in Sydney, Brisbane and Melbourne can take you right back into the action. Sydney is perfect for a long weekend of luxury comforts, fine dining, and high-end shopping. New Year’s Eve onboard a superyacht with the backdrop of Sydney’s Opera House and Harbour Bridge is certainly one for every owner’s bucket list. Head down to Melbourne, the events capital, for some of the world’s best events. From the Harbour, you are a short tender cruise from the major sporting events held throughout the year, including the Grand Prix, Melbourne Cup and Australian Open. Alternatively, a short walk down the newly renovated dockside will bring you to the Marvel Stadium, where leading artists flock to perform.

Indulge in infinite luxury

No matter where in the country your itinerary may take you, Australia’s highlife is never far away.

Premium superyacht marinas scattered across the islands lead into luxurious five-star resorts, leaving your yacht in good care while you delve into an authentic barefoot island retreat. Ideal for groups carrying a wide demographic, the Whitsunday Islands offer everything from chic beach glamour to high-octane water sports.

Should you wish to venture into Australia’s richly diverse regions, the Luxury Lodges of Australia will welcome you in sumptuous style. A collection of the finest lodges and camps around Australia, Luxury Lodges offers over 250 individual experiences and activities that connect guests to Australia’s most breath-taking locations, unlocking their curiosity and adventure-seeking spirit. The standards of comfort and service in Australia’s high-end heritage sites are parallel to that of a stay onboard one of the finest superyachts. Whether overlooking the Ningaloo Reef on Australia’s West Coast, staying in the world-renowned Barossa Valley wine region in Southern Australia or dining underneath the iconic Ayers Rock in the World Heritage listed Uluru-Kata Tjuta National Park, the Lodges deliver a truly special experience.

If you prefer not to stray too far from the natural playground of the Great Barrier Reef, Cairns and the Whitsunday Islands offer a selection of high-end luxury resorts. Surrounded by a bewitching blend of sublime landscapes, intriguing marine life and infinitely perfect anchorages, the tropical coast marinas offer something for every superyacht party. Superyacht owners have enthused that being able to explore the coastal towns without the need for a security detail has added a special touch to their Australian exploits.

World-class superyacht facilities

Nowhere else in the world can a superyacht sit so detached and isolated yet still be within a short cruise from premier, state-of-the-art shipyard facilities. Australia has a thriving refit and maintenance industry that has benefitted recently from significant investment to cater to larger vessels, meaning no project is too complex.

All along the East Coast there is an array of shipyards that constantly makes sure the South Pacific superyacht fleet is well serviced and pristine. The capabilities available are not to be understated. In Cairns, the world’s largest Mobile Boat Hoist at BSE Maritime Solutions gives the area significant pulling, and lifting, power. The City can accommodate superyachts of up to 140m in length, while highly experienced agents take great care in providing everything needed for a seamless transition from or to life at sea. Cairns itself provides the perfect setting for a superyacht homeport, situated between the Wet Tropics Rainforest and the Great Barrier Reef, two World Heritage listed natural wonders.

Queensland’s vibrant South East region boasts a similarly impressive offering. The well-established facilities in Brisbane and the Gold Coast have given the green light to significant investments as they prepare for an influx of visiting superyachts. Rivergate Marina & Shipyard has its own prominent international reputation, having completed over 250 superyacht projects since opening in 2006. Rivergate’s positioning on the Brisbane River provides easy access to both the bustling city and the immaculate cruising grounds of Australia and the South Pacific.

The Australia Marine Complex in Henderson, Western Australia is home to Echo Yachts and Silver Yachts, both multi-award-winning superyacht builders with glowing international reputations. The delivery of 84m trimaran White Rabbit by Echo Yachts in 2018 earned worldwide acclaim for reimagining the possibilities of comfort and efficiency onboard a superyacht. Superyacht projects undertaken in Australia not only benefit from the thousands of specialised trades that surround each facility and the historic expertise in aluminium, but also from the significant exchange rate advantage of the Australian Dollar.

New possibilities

With the intimacy of a small island and the might of a first world country, Australia is the South Pacific superyacht hub with a perfect balance to ensure there is never a dull moment. Some of the world’s largest superyachts frequent the sanctuary of Tropical North Queensland’s marinas as a homeport and gateway to the excitement of the South Pacific islands. Hollywood star Will Smith became the first to officially charter a foreign flagged superyacht in Australia following the passage of new legislation in 2019. Since then, interest in superyacht charters has blossomed from the tropical northern areas down to the isolated splendour of Tasmania.

FREQUENTLY ASKED QUESTIONS

Can i take a power yacht for a sea trial.

Buying a power yacht is an investment so it’s only reasonable to expect to try before you buy. 

Typically, a formal offer to purchase (subject to sea trial) will need to be made before you can take the yacht out for a spin.  We do encourage this as an important step in purchasing your vessel.

What are the benefits of using a broker when buying a power yacht?

A broker such as Power Yachts Australia will save you time and streamline the purchase process.  We will manage all the details for you and ensure the vessel is checked out thoroughly before sale. 

 When you enlist a broker, you avoid private sellers who may not be reliable and give you the runaround.

Can you connect me with service providers I may need for my power yacht?

Yes.  We have a list of reliable, relevant suppliers to recommend for everything you may need including cleaning, maintenance, crew, moorings, insurance, finance, equipment and more.

Billionaires like Jeff Bezos and Mark Zuckerberg spend six figures a year maintaining their superyachts. Here's how.

• Superyachts  are one of the most expensive assets money can buy.
• The true cost of ownership is even more, adding up to millions a year.
• Here's how much it costs to own a superyacht — and what that money is going toward.

Financial advisors are quick to warn prospective owners that a boat is nothing more than a hole in the water in which to throw money. When it comes to superyachts , you'd better have bags and bags of cash.

As one luxury agent told Business Insider at the Palm Beach International Boat Show: "Buying a boat, it's a huge purchase — and nobody needs a yacht."

A superyacht, generally over 30 meters long, is one of the most expensive assets money can buy, with the largest costing more than a lot of real estate or a private jet. Billionaires like Jeff Bezos, Mark Zuckerberg, and Steve Jobs each spent nine figures on their megayachts.

That doesn't include operating costs. Owners should expect to pay about 10% of a yacht's new-build price each year, experts told Business Insider. That's tens of millions of dollars annually for the most luxurious boats.

"It's a small-to-medium-sized business in its own right," said Jeffrey Beneville, a senior vice president at insurance company NFP, where he specializes in consulting clients about yachts.

Unlike many smaller boats, superyachts need staff, not just a captain. Some superyachts have space for dozens of crewmembers , including a chef, engineer, and masseuse for the guests onboard. Each gets an annual salary — the highest-ranking members earn six figures — and benefits. Eric Schmidt's yacht fits a crew of 28 for a ratio of about two crewmembers per guest.

Then there's fuel, dockage fees, routine maintenance, and insurance. The latter hinges on everything from the reputation of a yacht's shipyard to where an owner wants to take it (if a vessel is taking frequent trips to the South China Sea, for example, expect to pay a higher premium). If a superyacht has a support yacht — or a support superyacht, in Bezos ' case — expect to pay another 10% of that boat's price annually.

"The cost to maintain a yacht is so high that they just think that money's getting lit on fire," Matthew Fleissig, the CEO of wealth management firm Pathstone, told BI of his clients who choose to charter rather than own.

One of his firm's clients who does own has a 23-meter yacht valued at $5.2 million. The annual cost to staff, maintain, dock, and insure the boat is $346,297, according to documentation provided to BI. The lion's share is spent on marina fees ($95,970) and maintenance work ($88,408.) While not exactly a Sunfish, that boat is too small to count as a superyacht.

At 106 meters, the Amadea, owned by a sanctioned Russian oligarch , definitely does. The $300 million yacht, which was seized in 2022 and is docked in San Diego, cost $922,000 a month to maintain, a court filing showed: $360,000 for crew salaries, $75,000 for fuel, $144,000 for insurance, $178,000 in dry-docking fees, and $165,000 for maintenance, waste removal, food for the crew, and miscellaneous expenses.

"And that's an inactive yacht that's in the water," NFP's Beneville said.

If it were operational and carrying guests, the costs would be about twice that, or between $20 million and $30 million a year, he added.

Of course, it makes more financial sense for the non-obsessives to charter, and many of Fleissig's clients do. And some owners choose to offer their yachts for charter — the most luxurious cost as much as $1 million a week — to offset the costs.

"If you charter the boat for 50 days a year, it's going to help a lot," Anders Kurtén, the CEO of brokerage firm Fraser Yachts, told BI.

Then again, the running costs don't matter as much at a certain point. "If you're worth $30 billion, it's nothing. And if you're worth $117 billion — and these are the guys we're talking about — they're in it as long as it's still enjoyable for them," Beneville said. "It's not a money thing."
