Super Shark Highway

Embark on a dangerous tagging mission in South Australia that will show what sharks eat and why they gather in feeding hot spots. Then head north as a team chases tiger, bull, and hammerhead sharks and outfits one with a 360-degree dorsal camera.

Track a pregnant shark along the Great Barrier Reef and see if she leads a team of scientists to her hidden pupping ground. Then search for signs of mating along the southern coast that could reveal a very shy female megashark in search of a partner.

Stay up late as the northern team attaches an activity tag to a bull shark and finds out what this night owl does after sunset. Then dive 80 metres deep with the southern team, who are hoping to put a satellite tracker on a female great white.

Ponder shark community hierarchies as the northern team studies how young blacktips learn social and survival skills. Then rush to Rainbow Beach with the southern team, who are eager to witness the sand tiger shark’s most elusive behaviour: mating.

Travel to the ends of Australia’s shark highways. Find out if Greenly Island in the south is a truck stop for migrating great whites, then search for proof of a genetic connection between northern bull sharks and their cooler-climate cousins.

Follow the southern team as they test new migration tech and tools that could reduce shark attacks in a popular snorkelling spot. Then catch and tag bull sharks with the northern team, who want to help local swimmers steer clear of birthing mothers.
