An Australian billionaire's $137 million Fiji resort

Lang Walker made his estimated $3.1 billion fortune by developing some of Sydney's most iconic sites, Finger Wharf and King Street Wharf. But one of the only things those projects share with his latest endeavour, a private island resort in Fiji, is a nine-figure price tag.

"This is the only project I've ever really fallen in love with," said Walker, 72. It's also the first one he hasn't seen as a business decision or moneymaker. Instead, Kokomo Private Island Fiji is a passion project, pure and simple. With just 21 villas on the site of an abandoned, half-built Aman resort, all with access to the world's fourth-largest coral reef, Kokomo is meant as an oasis for Walker's family that he can also share with the world. It was so personal, in fact, that he eventually multiplied his original $13 million budget by at least 10-a spend that's rare for a resort so small.

Even before the hotel soft-opened last year, it was "beyond a 'project for profit,'" Walker told Bloomberg in an interview. "I'm told I can't go over there too much because every time I have a new idea, that costs money."

But Walker is developing the resort with the same eye toward sustainability and innovation he's used on his company's latest initiative, Melbourne's $3.4 billion Collins Square. With new food and beverage offerings, a hilltop gym, a spa expansion, and a hydroponic nursery coming to Kokomo this year, he's evolving the property in hopes that it will join a shortlist of the world's best resorts.

"I've done many wild and different things, but never an island, so there was a cheeky I-wonder-what-it's-like feeling," said Walker.

The relatively remote island of Yaukuve Levu, in Fiji's rural southern Kadavu island group, was ideal: It has four pristine beaches; there are virtually no other hospitality venues nearby; and guests have easy access to one of the world's most epic dive sites, the Great Astrolabe Reef. "In 10 minutes you're diving in a massive drop-off among fan corals," he said.

Besides the 21 sprawling, thatched-roof villas, Walker envisaged butler service, a child-care center and a massive organic garden. His goal: to create an intergenerational getaway with a minimal carbon footprint.

"I thought, This'll be pretty easy-maybe 18 months I can have it up and running. Maybe a budget of $13 million," Walker said, laughing. But creating a luxury resort on a far-flung island had some serious initial impact: It called for a seaplane, a helicopter, two barges, and a fleet of recreational boats to cater to his $10,290-a-night guests. He also added five residences to the original plan, each with three to six bedrooms; spent lavishly on local materials like cinnamon wood; and splurged on unseen details that streamline back-of-house operations. By the time Kokomo welcomed its first guests six years later, Walker had invested at least $137 million.

Kokomo's design amalgamates the best parts of Walker's favorite resorts around the world. Lush landscaping and privacy walls were taken from nearby Laucala Island, the restaurants' casual vibe from Nikki Beach St. Barth. The villas have outdoor showers, private infinity pools, massive decks and Veuve Clicquot-stocked minibars.

But the goal is to make this luxury you can feel good about. The list of sustainability features includes an on-island water filtration system, graywater system, and sewage treatment plant. There's also a tiered organic garden, free-range chicken coop, beehives, and soon a flock of ducks-for farm-to-table Peking duck at the Asian restaurant, Walker d'Plank. This strategy serves multiple ends, said Walker: "It's far more economical than importing frozen things."

Want to get involved? A coral gardening and restoration project allows guests to harvest and propagate healthy super-coral fragments-one way Walker is ensuring that the pristine marine environment continues to look and feel untouched.

Walker was prepared to execute an eco-sensitive vision, but cultural sensitivity wasn't on his radar: Yaukuve island is uninhabited. Still, chiefs from neighboring islands expected a say in Kokomo's business plan. Over several kava ceremonies-a tradition that involves sharing stories over sips of bitter pepper tea-Walker took note of the local needs, from employment to education and economic stimuli. In return, he promised to support the islands' schools, train Fijians to work at the resort, and set up bank accounts for anyone in need.

Time will tell how well Kokomo and the community can integrate, but Walker is off to a promising start. He's helped rebuild a school that was damaged by cyclone Winston and is supported sports programs in the villages. But employment is where he's made the most progress. "In this part of Fiji, there's been no tourism of any note, and employment opportunities are lacking," Walker said. "I figured it was good to get that going."

Now 94 per cent of Kokomo's staff come from Fiji, with 65 of the 238 staffers hailing from the two closest islands.

Local staff members are just one way the resort feels distinctly Fijian-they greet guests at the helipad and jetty and infuse the day-to-day experience with genuine warmth, even if they are still learning the ropes of running a luxury resort. Instead of attending cheesy luaus and tiki parties, guests can hike to secret waterfalls with local guides or try their hand at spear-fishing wahoo or mahi-mahi.

Everything that's caught gets prepared at the white-tablecloth, open-air Beach Shack restaurant. Crowd-pleasing staples such as wood-fired pizza are available by the pool, and at the waterside Walker d'Plank, self-trained Fijian chef Caroline Oakley designs each meal on the spot rather than handing out menus.

As much as Kokomo is a lazy, indulgent place for guests-its name is shared with Walker's three superyachts-the resort will keep its owner busy for quite some time. First he has to break even on the project, which he says he can do even if he manages to just keep the resort at just 50 per cent occupancy year-round and sell a few of the luxury residences, whose prices will start at about $20 million when they go on the market in 2020.

"I don't think I'm ever going to get rich on owning an island in Fiji," joked Walker. But he's not worried about that. "The minute you start putting money ahead of excellence, it doesn't work," he said. "The money side of things follows from all the things you do that add up to excellence."
