2XU Ocean Swim Series - Carlton Beach Ocean Swim

Carlton Beach fronts some of the clearest, purest ocean waters in Tasmania. The 2XU Ocean Swim Series - Carlton Beach Ocean Swim is an open water swimming race held in the sea at Carlton Beach, in south-eastern Tasmania, Australia. Swimmers gather on one of Hobart's favorite local beaches, stepping onto soft sand before plunging into the crystalline salt water. The event is held in March during the southern late summer, when the maritime conditions along the Tasmanian coast offer invigorating, transparent swimming. Organized by Surf Life Saving Tasmania, the competition features course options of 500, 1000, and 2000 metres to welcome both sprint swimmers and endurance specialists. The swim courses are designed as loops hugging the beach, utilizing triangular or rectangular layouts that allow for straightforward sighting on the water.

Sighting remains simple as swimmers track the markers along the sandy shallows. Because coastal swells and tides can alter the state of the sea, organizers adjust the exact course layout on the day according to local conditions. Swimmers navigate the rhythmic Tasmanian chop with confidence, guided by clear turns and beachside landmarks. Carlton Beach also serves as the venue for the Clearwater Classic, a swim within the Tasmanian Ocean Swim Series. That event offers a 1,500-metre long course and a 500-metre novice swim. Life on the shore is anchored by the Carlton Park Surf Life Saving Club, established in 1975. The gathering is known for its warm, laid-back community atmosphere where competitors, surf lifesavers, and spectators mingle. After finishing their swim and crossing the soft sand, participants can head straight for a warm shower, grab a hot coffee, and relax while socializing under the surf club balcony.

Carlton Beach: the 2.7 km shore

Carlton Beach lies 40 km east of Hobart and is a popular summer surfing destination. The beach is 2.7 km long and faces south-southwest toward the entrance of Frederick Henry Bay, 15 km to the south. It is bounded by the Carlton River mouth and Carlton Bluff to the east and by Spectacle Head to the west. A coastal reserve containing 10-15 m of small dunes backs the entire beach. Holiday houses and permanent residences sit alongside the reserve, overlooking the beach. Public toilets and designated car parks are located at both Carlton and Park Beach.

Frederick Henry Bay: navigational chartings and historic shorelines

Long before maritime charts recorded this coast, the estuarine margins of Pitt Water, located about seven kilometres from Carlton Beach, were frequented by the Moomairremener people for hunting and gathering. European explorers arrived in the seventeenth century, when Dutch navigator Abel Tasman named Frederick Henrik Bay in 1642 in honor of Frederick Henry, Prince of Orange. More than a century later, French expedition leader Bruni d'Entrecasteaux mapped the expansive marine inlet as Baie du Nord in 1792–93. Navigators such as Henri Peyroux de la Coudreniere noted the bay as an excellent natural harbour, sheltered from winds and offering soundings of 14 fathoms in depth. About fourteen kilometres across the bay from the race area, Sloping Island was charted by d'Entrecasteaux under the name St. Aignon on his map.

A shore-based whaling station commenced operations there in 1824, remaining active through the 1820s. Towards the head of the bay about five kilometres from Carlton Beach, civil engineering shaped the shoreline when the Sorell Causeway was built using convict labour and completed in 1872. Swimmers can take on the open sea knowing experienced crews in rescue craft watch over every stroke.

Pitt Water: Ramsar wetlands and restored tidal channels

About seven kilometres from the race area, the coastal ocean joins Pitt Water, an extensive 43.1-square-kilometre estuarine system directly connected to the Tasman Sea. A main channel running 12 kilometres in length with an average depth of 8 metres facilitates the continuous movement of ocean water into the protected basin. In 1982, the Pitt Water–Orielton Lagoon system earned global recognition when it was officially designated as a Ramsar Wetland of International Importance. Crossing the estuary near Sorell about six kilometres from Carlton Beach stands McGees Bridge. This crossing sits within the internationally recognized wetlands site and a designated heritage area, where tidal currents sweep beneath the structure. To restore healthy ecological conditions, engineers modified the causeway by cutting dedicated sluice conduits and installing a new pile system to improve water flow. The expansive mudflats also support vital populations of migratory waterbirds, including the eastern curlew and the red-necked stint.

Sloping Island Group: offshore sanctuaries for coastal wildlife

Located about fourteen kilometres from the race area near the entrance of Frederick Henry Bay, Sloping Island encompasses a 117-hectare nature reserve in south-eastern Tasmania. The island forms a critical breeding sanctuary for native seabirds, providing nesting territory for little penguins, short-tailed shearwaters, Pacific gulls, sooty oystercatchers, and pied oystercatchers. Within Pitt Water, Woody Island spans approximately 28.3 hectares and features sheer cliffs rising 15 metres above the tide. Part of the Sloping Island Group near the Tasman and Forestier Peninsulas, Woody Island underwent significant environmental restoration when introduced rabbits were eradicated in 1990. An ecological survey conducted in 2001 recorded flora including boxthorn, blackberry, mirror bush, and historical Monterey pine growing across its slopes.

Out in the Sloping Island Group near the Tasman and Forestier Peninsulas, Spectacle Island covers 3.5 hectares of sheltered habitat. The island provides protected breeding grounds for colonies of little penguins, short-tailed shearwaters, and pied oystercatchers. Positioned right next to Spectacle Island is Little Spectacle Island, a tiny outcrop covering just 0.62 hectares near the south-eastern coast of Tasmania. This companion islet, also part of the group near the Tasman and Forestier Peninsulas, serves as a breeding site for little penguins, silver gulls, and crested terns. Completing the Sloping Island Group off the south-eastern coast of Tasmania is Barren Island, a miniature landmass covering just 0.53 hectares in south-eastern Australia. Even in this windswept setting, seabirds find reliable refuge: silver gulls and kelp gulls use Barren Island as a regular breeding ground. On the ground, the island shelters populations of the three-lined skink among its rocky crevices.
