juvenile black marlin fishing

Adult Black Marlin are referred to as "rhinos of the sea," due to their spear like nose and mammoth size. Fully grown females are the largest, and can weigh as much as 450kg! As the ultimate game fish, the giant Black Marlin is accredited for making Cairns a world-class fishing destination. To hook your own Marlin, you don't need to charter a boat out of Cairns or any of the other Marlin hot spots. You just have to think smaller.

They can be caught with light tackle and don't require expensive, high-end game fishing gear or a deep sea boat. Fishing little Black Marlin can be done near shore with gear many anglers already have.

Huge numbers of young Black Marlin then migrate south during the summer months, making this game fish highly accessible to all anglers in the region. They can be readily available on the eastern seaboard, just outside of the Moreton Bay Islands from the end of December to early April. The exact timing of the Black Marlin arrival is dependent on:

  • currents
  • sea surface temperature
  • the presence of flood waters
  • food sources

Marlin will migrate with strong, blue inshore currents from the north.  Flood waters that push out brown waters will halt their migration down the coast.  These young fish are seriously hungry and grow very quickly. They need schools of yellowtail, pilchards and slimy mackerel to keep them well fed and present in any location. Another indication of a great run with young migrating Black Marlin is if the major fishing locations further north had a great season. If they did well, you can expect your turn at the reel will be equally exceptional. To get the correct timing, keep a look out for strong inshore currents from the north, lots of Marlin bait, no brown flood water, and reports from anglers further north.
