Kingscote Jetty

Kingscote is the island's biggest town and its jetty is the platform every other Kangaroo Island mark gets measured against. The main jetty was rebuilt in 2006 at 302 metres, 8.4 metres wide for half its length and 3.3 metres for the rest, and the deck still carries light vehicles. It was partially closed to pedestrians and vehicles from December 2020 after an engineering report found deteriorating piles. The refurbishment that followed put new piling, cross bracing and decking across the main jetty, Fisherman's Jetty and the old screw pile jetty, and it was handed back in early April 2023 with a further 30 years of design life. A jetty that was shut, fixed and then given three decades is not the usual story on this coast. The department that owns it still names Kingscote first when anglers ask where to go while the Penneshaw jetty is closed. What makes it worth the drive is the bottom: broken ground runs a kilometre either side of the deck, and King George whiting come over it after dark, which makes this one of very few shore marks in South Australia where whiting are a night fishery.

The night session is the whole point. Whiting sit on the broken bottom under and around the deck, so a light outfit and a moderate cast onto the rubble edges does the job — this is not a jetty where you need to reach the horizon. Snook are the second act and the technique is specific: a whole blue bait drifted with little or no weight on calm nights, or the same bait worked slowly through the light spill when the fish are actively feeding. Tommies stack up from the late afternoon into the evening and take small baits under a float or a bait jig fished under the deck. Trevally, salmon trout, mullet and flathead fill in the rest of a session, and a passing yellowtail kingfish in summer is the deck's lotto ticket. Fisherman's Jetty, the smaller wooden deck 200 metres north, fishes whiting, tommies and snook but holds about half a dozen anglers before it is full. The tidal pool breakwater 630 metres south-west is the third mark and the one to take kids to. Calamari and garfish were both staples here and both are closed, which strikes two names off the deck's list.

King George whiting are the reason to come, and the numbers moved in 2026: minimum 32 cm, with a Gulf St Vincent and Kangaroo Island bag of 5 and a boat limit of 15. The old guides talk about locals bagging out on whiting from these planks, which is still true, it is just a shorter evening than it used to be. Tommy ruff have no minimum size and a bag of 40. Snook are 45 cm with a bag of 10 in this zone, trevally 24 cm and 10, flathead 30 cm and 5, and yelloweye mullet 21 cm and 30. Australian salmon run two-tier statewide — 20 fish between 21 and 35 cm, or 10 fish over 35 cm — and yellowtail kingfish are 60 cm with a bag of 1. Southern calamari has been closed to targeting, taking and possessing across both gulf zones since 1 May 2026 with no end date published, and garfish has been closed in the Gulf St Vincent and Kangaroo Island zone since the same day. Snapper is closed until at least 30 June 2027, with catch and release included in the ban. Sand crabs are the real Kangaroo Island crab at 10 cm and a bag of 10 in this zone, but the Bay of Shoals sand patches the old guides send you to sit inside a sanctuary zone, so that advice no longer survives the map.

Come at night and bring your own light. The jetty lights are real and the snook use them, but nothing about the deck's lighting is documented well enough to plan a trip around, and a headlamp matters when a whiting has to be measured against 32 cm in the dark. Take your line home with you: leafy seadragons live on these pylons, and they were among the species worst hit by the algal bloom. That bloom is the other thing an honest page has to carry. Bay of Shoals, the water immediately north, was hit hard by Karenia through autumn and winter 2025, with mass deaths of fiddler rays, razorfish clams, worm eels and rock crabs, and volunteers spent that spring marking out damaged eelgrass beds. Testing has since shown zero or low Karenia along the metropolitan coast since February 2026, with elevated pockets still recorded on Eyre and Yorke as late as July, which is the half of the story the doom posts leave out. If the deck is crowded, Fisherman's Jetty is 200 metres north and the tidal pool breakwater 630 metres south-west. Anyone with a boat should note the Nepean Bay artificial reef about 8 km south-east is closed to all fishing until roughly 25 May 2027.

The jetty runs off the Kingscote foreshore at the end of the town's main street, with foreshore parking a few steps away including a signed four-hour bay. The deck is flat and wide and carries light vehicles at 10 km/h under a 4.5-tonne limit, so the walk out is easy, but toilets, cleaning tables, rails and formal accessibility at the jetty itself are not documented anywhere reliable. Kingscote is the island's largest town and the rest is within a few hundred metres: supermarkets, fuel, a pub, a bakery, tackle and bait, and the hospital, with the airport 14 km away. The tidal pool precinct 630 metres south-west has a sealed carpark, a fenced seawater pool with floating pontoons and a breakwater, and it is the kid-friendly end of the foreshore. The Bay of Shoals boat ramp is 2.6 km north-west with a 5-tonne limit, and it sits about 700 metres outside the sanctuary zone's western corner, so it launches you into legal water rather than into the no-take line. Fishing the jetty is free, and South Australia has no general recreational fishing licence.

Kingscote faces east-north-east into Nepean Bay from the bay's western shore, so westerly and south-westerly weather blows offshore and flattens the water in front of the town. Easterlies and north-easterlies do the opposite and put chop straight onto the deck. A light southerly is the pick for the marks either side of the jetty. Kangaroo Island's tidal range is modest but its currents are not, and the Bay of Shoals channel runs hard enough that sinker weight becomes an hourly decision. South Australia's fortnightly dodge tide still flattens the movement for a day at a time, so plan around a running tide after dark rather than around tide height. Winter brings the fat whiting, and summer brings tommies, holidaymakers and the occasional kingfish.

The deck carries vehicles at 10 km/h under a 4.5-tonne limit, so it is a road as well as a fishing platform. The water off Kingscote is shallow and the historic complaint about it still holds — at low tide the sea recedes a long way from the end of the jetty, and wading this foreshore at low water is a mud-and-seagrass exercise. The main fishery is a night fishery, so treat a headlamp and a spare as standard rather than optional. Sea lions haul out on and around the structure and long-nosed fur seals work the pylons, so do not feed them, do not fish beside them, and expect to lose the occasional hooked fish. Leafy seadragons live on the same pylons, which makes discarded line and lost jigs a real risk to a protected species. The Bay of Shoals Sanctuary Zone starts 3.0 km north of the jetty and no fishing of any kind is allowed inside it, with the Bay of Shoals boat ramp about 700 metres outside its western corner, so read the signs before you motor north. Busby Islet, 3.6 km north, is a restricted access zone with no entry at all.

Yes. The main jetty, Fisherman's Jetty and the old screw pile jetty were refurbished together with new piling, cross bracing and decking, and reopened in early April 2023 with a further 30 years of design life. It had been partially closed from December 2020 after an engineering report found deteriorating piles.

King George whiting after dark, tommy ruff from the late afternoon, snook under the jetty lights, plus trevally, salmon trout, yelloweye mullet, flathead and the occasional summer yellowtail kingfish. Southern calamari and garfish are both shut in this zone, and snapper stays closed until at least 30 June 2027.

Not legally right now. Southern calamari has been closed to targeting, take and possession across Spencer Gulf and the Gulf St Vincent and Kangaroo Island zone since 1 May 2026, with no end date published. The closure bans targeting rather than only the take, so even working a jig breaks it.

No. The Bay of Shoals is Sanctuary Zone 8 inside Encounter Marine Park and no fishing of any kind is allowed there, which catches out a lot of people because it looks like obvious fishing water. The legal platform is the Kingscote town jetty, 3.0 km south of the zone edge, and the boat ramp sits about 700 metres outside the zone's western corner, so read the signage before you motor north.

32 cm, with a bag of 5 per person and a boat limit of 15 in the Gulf St Vincent and Kangaroo Island zone. Those bags were halved in this zone and the current table dates from 1 May 2026, so anyone working from an older guide is planning around the wrong number.
