Border Island

Secluded uninhabited island with pristine Cateran Bay, protected for over 80 years as a Marine National Park Green Zone

About Border Island

Border Island is a small uninhabited island located east of Hook Island and Whitsunday Island in the Whitsunday Islands National Park. This secluded island is a local favourite among sailors and experienced cruisers seeking pristine natural beauty away from the day tour crowds. Protected as a Marine National Park Green Zone since the 1930s, Border Island has enjoyed over 80 years of conservation, resulting in abundant marine life, thriving birdlife, and exceptionally clear waters.

The island's main feature is Cateran Bay on the north coast, a unique sandy beach surrounded by steep, tree-clad slopes that create a profound sense of seclusion. This protected anchorage has made the list of top 10 beaches in the Whitsunday region and is particularly popular with couples seeking a romantic escape where they can have the beach entirely to themselves. The secluded sandy beach is accessible at mid to high tide and offers crystal-clear water for swimming and snorkelling directly off the beach or from anchored vessels.

In 2018, Queensland Parks and Wildlife Service completed a 1.2-kilometre return walking track to a lookout at the island's peak, providing stunning views over Cateran Bay, Hayman Island, and Hook Island. The Class 3 stepped track is steep and suited to those with bushwalking experience, meandering through low scrubby bushland with giant grass trees before emerging at lookout points along the island's saddle. Border Island is positioned conveniently between Airlie Beach and popular destinations like Whitehaven Beach, making it an ideal lunchtime stopover or overnight anchorage for sailing itineraries.

What to Expect at Border Island

Border Island offers a dramatically different experience from the busier Whitsundays destinations. As an uninhabited and undeveloped island that commercial tour boats rarely visit, visitors can expect true seclusion and tranquillity. The protected Cateran Bay creates an incredibly peaceful atmosphere - so quiet at night that the stillness can be almost eerie. With free public moorings available and typically only one or two other boats in the bay, you may have the entire beach to yourself, creating a genuine private island paradise experience.

The marine environment at Border Island is exceptional due to its long-term protection as a Green Zone. Beautiful plate coral thrives in the shallow waters of Cateran Bay, while the southwest and southeast flanks offer excellent snorkelling and diving opportunities, particularly at Pitstop Bay in northerly winds. The water clarity is pristine, though visibility can vary with tide changes. Snorkellers can expect to encounter diverse marine life including turtles, manta rays, colourful tropical fish, and abundant coral formations. The scattered bommies at the back of the bay and the site known as Boulders on the eastern edge provide particularly rewarding underwater exploration.

The bushwalking track offers a steep but rewarding climb with no tree canopy, meaning full sun exposure throughout the ascent. The open landscape provides unimpeded views from the moment you start climbing, with tall black spikes of giant grass trees rising overhead. At the summit, expansive panoramic views stretch across the Whitsundays, making the challenging hike worthwhile. The beach at Cateran Bay is small but beautiful, surrounded by tall cliffs and crystal-clear water perfect for swimming, beach picnics, and sunset watching. There are no facilities whatsoever on the island, reinforcing the pristine, untouched nature of this special location.

How to Get to Border Island

By Sailing Charter

Border Island is accessible exclusively by boat and is a favourite destination for bareboat charters and crewed sailing vessels exploring the Whitsundays. The island's position east of Hook Island makes it far enough from the day tour crowds while remaining within comfortable sailing reach from Airlie Beach or Shute Harbour. Many overnight sailing tours include Border Island as part of multi-day itineraries exploring the northern Whitsundays.

By Private Boat

Private vessels can pick up one of the free public moorings in Cateran Bay, which are positioned to minimise impact on the fringing reef. The island is too small for any jetty construction, so visitors must either swim or use a dinghy to reach the beach from their anchored boat. Overnight mooring is permitted in calm conditions, with the bay offering protection from most wind conditions, though strong currents can develop at the entrance, particularly at the northwest tip. Watch carefully for isolated submerged coral heads in the mooring pickup area.

As a Stopover

Border Island's location on the route between Airlie Beach and Whitehaven Beach makes it an excellent lunchtime stopover for snorkelling and exploring. Those with more time should consider anchoring overnight to fully experience the island's secluded beaches, fantastic snorkelling, and the stunning bushwalk to the lookout.

Essential Information

Best Time to Visit

Border Island can be visited year-round, though dry season (April-October) offers the most comfortable conditions with calm seas and minimal rainfall. The beach at Cateran Bay is best accessed at mid to high tide. Snorkelling conditions are excellent in northerly winds at Pitstop Bay on the southeast flank. The protected anchorage provides good shelter in most weather conditions, though be aware of strong currents at the entrance, particularly during tide changes. For the bushwalk, early morning or late afternoon visits avoid the hottest part of the day, as there's no shade along the track.

What to Bring

Border Island has no facilities, so come completely self-sufficient. Essential items include plenty of drinking water, food and snacks for the day, comprehensive sun protection (hat, sunscreen, rashie, sunglasses), snorkelling gear (mask, snorkel, fins), stinger suit during marine stinger season (November-May), sturdy hiking shoes with good grip for the walking track (not flip-flops or sandals), beach towel, camera, and reef-safe sunscreen. For overnight stays, bring all provisions, cooking equipment, and rubbish bags. The walking track has no shade, so protective clothing is essential.
