Course Description

The swim starts at Cairns Airport, launching athletes over the crystal‑clear waters of the Great Barrier Reef. After the swim, participants transition to a fully closed coastal highway that hugs the shoreline, offering uninterrupted views of coral islands and the Daintree Rainforest. The bike leg is flat and fast, ideal for personal bests. The run finishes on the main strip of Cairns, a wide, paved road lined with cheering locals and vibrant banners, providing a festive and flat finish that rewards every effort.

Getting There

Cairns Airport is the race hub; follow signs to the designated parking area (free for participants). Shuttle buses run between the airport, Palm Cove, and the start line every 30 minutes. Queensland Rail’s Spirit of Queensland service stops at Cairns Station, a 10‑minute taxi ride to the venue. Arrive at least two hours before your start to allow for check‑in and gear set‑up.

Weather & What to Pack

June is winter in Australia, but tropical North Queensland stays warm. Expect daytime highs of 18‑29 °C (65‑84 °F) with mild humidity and occasional light showers. Morning breezes can feel cool, so a light jacket or long‑sleeve top is advisable. Stay hydrated and use sunscreen – the sun can be strong even in winter.
