Where Does the Southern Garfish Live?
The Southern Garfish is native to the temperate coastal waters of the Southern Hemisphere, specifically surrounding the southern half of Australia and the shores of New Zealand. In Australia, their range spans from the northern waters of New South Wales, down through Victoria and Tasmania, and across the Great Australian Bight to Shark Bay in Western Australia. They are a staple species of the cool-temperate maritime regions, rarely venturing into truly tropical or sub-antarctic zones.

Behavior
Southern Garfish are highly social, schooling fish that inhabit the upper layers of the water column. They are most frequently found in sheltered coastal waters, where they utilize seagrass meadows for both foraging and protection. One of their most distinctive behaviors is their ability to 'skip' across the water's surface; when threatened by predators like salmon or silver trevally, they leap into the air and glide briefly to escape.
These fish are generally shy but exhibit a curious nature toward floating objects. During the day, they congregate in large numbers under jetties and piers, which offer shade and protection from aerial predators like cormorants. Because they are surface-dwellers, their activity is highly influenced by the tide and light penetration, becoming particularly active during the rising tide as it pushes over shallow flats.

Camera Tips
Capturing Southern Garfish on camera requires a specialized approach since they live just below the water's surface. For the best results, use an AI-powered underwater action camera mounted to a weighted tripod or a jetty pylon. Position the lens just 10 to 20 centimeters below the water line, angled slightly upward. This captures the shimmering reflections of their silver scales against the surface 'mirror,' which is a hallmark of this species' aesthetic.
Because they are visual feeders, you can attract a school to your camera using a slow-release burley bag filled with fine breadcrumbs or pollard. Secure the bag within the camera's field of view but slightly off-center to ensure the fish remain the focal point. The best time to film is mid-morning when the sun is high enough to penetrate the water but hasn't yet created harsh vertical shadows, allowing their iridescent silver stripe to pop against the green seagrass background.
If you are filming from above the water—such as from a backyard pier or canal wall—a circular polarizing filter is absolutely essential. This filter will cut through the surface glare and reflections, allowing your camera to see clearly into the water column. Set your camera to a high frame rate (at least 60fps) because Garfish move with sudden, darting bursts of speed that can easily become a blur on standard settings.
