Giant Black Marlin Fishing In Cairns – Aboard Calypso
Cairns is recognised worldwide as the home of giant black marlin — the only place on earth where fish exceeding 1,000lb are reliably caught year-after-year. Each season, anglers travel from across Australia and around the globe for a chance to experience the heavy‑tackle marlin fishing on the Great Barrier Reef at its best.
Aboard Calypso, you’ll be fishing these legendary waters with an experienced and professional crew with a deep understanding of the fishery.
Giant Black Marlin Season – September to December
From September through December, the reef systems off Cairns plays host to an aggregation of black marlin along a section of the Great Barrier Reef called the Ribbon Reefs which runs north from Cairns up to the famous Lizard Island.
The unique combination of reef structure, bait aggregation, water temperature, and seasonal currents create conditions found nowhere else on the planet.
This is the reason the fish return to the reef year-after-year and is why Cairns remains the number one destination for giant black marlin fishing.
