Bondi Beach is known for surfers, swimmers and tourists—but now it has an unexpected seasonal visitor. Scientists from Deakin University have discovered that Yellowtail Kingfish, a prized catch for recreational anglers, head to Bondi during the colder months.

The finding comes from a large-scale tracking project in which 40 kingfish along Australia’s east coast were fitted with acoustic tags. Data revealed that the fish, commonly caught in Victoria, move across Bass Strait after summer and migrate north to spend winter in Bondi’s waters.
For saltwater fishers, kingfish are among the most sought-after catches, especially along the stretch from Mallacoota to Portland and in the southern waters of Port Phillip and Western Port.
This breakthrough sheds light on a long-standing mystery about the species’ movements. Kingfish are highly sought after, yet researchers have known little about their migration patterns or breeding behaviour. Early results suggest they may be spawning in warmer waters, possibly off New South Wales seamounts, but more data is needed to confirm.
The project is being powered by recreational fishing licence fees through the Victorian Fisheries Authority, with additional support from Project Kingfish, which is also deploying satellite tags. By uncovering where these fish travel and reproduce, scientists hope to provide vital information for fisheries management.
The Victorian Fisheries Authority is already considering changes to catch limits, aiming to ensure the sustainability of kingfish stocks while still allowing anglers the thrill of reeling in these powerful fish. Local fishing clubs are also being encouraged to take part in tagging programs to help expand the research.

“The proposed change would leave more kingfish in the water to be shared amongst experts and beginners and encourage responsible fishing practices that balance taking home a meal of fresh fish with continued improvements in local stock levels,” the Victorian Fisheries Authority stated.
For Bondi, the discovery highlights the beach’s role not only as a global destination for people but also as an important stopover for marine life. As scientists continue to track these ocean travellers, Bondi’s waters may become a key piece of the puzzle in protecting one of Australia’s most prized recreational fish.
