Emu Bay Jetty sits on the north coast of Kangaroo Island in a bay that looks across toward the Yorke and Fleurieu peninsulas, its water generally calmer and clearer than the exposed southern shores of the island. It is a quieter site than Kingscote Jetty, less trafficked, less known, and with the particular appeal of a dive where there is every chance of having the water to yourself.

Emu Bay is a shallow, sheltered embayment on the island's northern coast, its sandy foreshore and coastal dunes giving way below the waterline to a sand and seagrass environment that extends across the bay floor. The jetty is a modest structure, but it has been in place long enough for the pylons to carry a layer of encrusting growth that supports the predictable community of small organisms on which South Australian jetty diving depends. This is a productive and uncomplicated dive.

The depth is shallow throughout, 1 metre at the shore end, deepening gradually to around 7 metres at the outer pylons. The bottom is predominantly sand and shell grit with seagrass beds extending away from the jetty structure on both sides. The pylons carry sponges and ascidians in reasonable variety, and the seagrass directly adjacent to the structure provides the habitat that weedy sea dragons favour. Leafy sea dragons are less commonly seen here than at the Fleurieu sites but are recorded with enough regularity to make them a realistic expectation rather than a wishful one. Giant cuttlefish occupy the mid-water column under the jetty and on the sandy edges of the seagrass beds, and their interaction with the environment, the textural changes, the directional colour bands, the deliberate movement, is never less than engaging.

Visibility in the sheltered northern bay is generally consistent, 8–12 metres is typical in settled conditions, with some reduction in summer when algal activity increases. Water temperature tracks the island's position between the gulf and the open ocean, running slightly cooler than the mainland gulf sites: 13–20°C seasonally. The bay's northern exposure means it is well-sheltered from southern weather but can be affected by strong northerly winds, which are less common and shorter-lived than southerlies.

The remoteness of the site within Kangaroo Island is worth factoring into planning. The nearest hospital is in Kingscote. There are no tank fills at or near Emu Bay. A dive here works best as part of a wider day exploring the island's northern coast, rather than a sole destination from a Kingscote base.

## Site Access and Logistics

Emu Bay is on the northern coast of Kangaroo Island, approximately 35 kilometres northwest of Kingscote via the Playford Highway. Entry is directly from the jetty steps. Open Water certification is appropriate for this dive. Plan tank fills and equipment from Kingscote before heading out to the northern coast.
