Tavanipupu Private Island Resort, Solomon Islands: The South Pacific's best kept secret

We're experiencing a Pijin language version of 'Who's on First'. Nudagus is telling us he is not the most important Gus on Tavanipupu Island. "There's another Gus," he says. "The other Gus is the boss so I'm 'Nudagus'. A-nother-Gus." He points to his 'Nudagus' nametag.

Right now Nudagus is more important than the other Gus as Nudagus is the Gus bringing the cocktails. We wonder whether he is called 'Nudagus' at home or what his name would be if the other Gus left the resort. But that way lies madness and we return to gazing at the radiant sunset over the lagoon.

Tavanipupu Private Island Resort is the Solomons' most luxurious destination. Located in Marau Sound in Guadalcanal Province, it's 25 minutes by air from Honiara in an eight-seater Islander aircraft to a grass airfield, followed by a 20 minute boat ride to the resort.

The manicured resort is as stunning in real life as anything you could find in a travel brochure. There are just 11 bungalows of three different classes plus a 'Royal' bungalow and each is free-standing, spacious and quite luxe, certainly by Solomon's standards. All wooden with thatched rooves, vaulted ceilings and 'kastom' (traditional) furnishings and décor – plus shells and flowers – the bungalows reflect the serenity and beauty of the resort. My four-poster king bed is enveloped by a sprawling mosquito net that sways under the ceiling fan, the bathroom is modern and expansive and a porch with a day bed, hammock and lagoon views beckons.

Don't expect Wi-Fi, TV, air-con or drinkable tap water in your room. You won't miss them anyway. Tavanipupu is about the languid lagoon, sultry breezes, scuttling hermit crabs, reef snorkelling with endless visibility and the get-away-from-it-all story of a lifetime. They do have room service though – just bang the drum on your front porch and you'll get Nudagus. (Or Anuda-staffer, but let's not start that again.)

Anuda drum announces that lunch or dinner is served in the open-air dining room next to the bar. The menu mostly consists of fish from the lagoon and their own organic vegies and eggs. The meals we have are excellent and we also enjoy a breakfast on the porch, delivered right on 'Solomon's time' – 45 minutes late. Which couldn't have mattered less. Romantic dinners on the jetty are also popular.

In addition to the sublime snorkelling, you can explore the island by bike or on foot and the tranquil lagoon by kayak or paddle board, although some parts of the lagoon are culturally significant and off-limits to women. All genders can take a sunset cruise, go on the market trip to Marau station on Thursdays or join a fishing expedition ($AU150) to catch your dinner. You can arrange a day on your own sandy cay with a gourmet lunch and there's even a cosy little overwater Spa where you can have a massage while gazing into the water.
