Practical coastal guide
Yorke Peninsula crabbing · Oyster Bay shallows · Stansbury Jetty · season, tides and rules
On the Gulf St Vincent side of Yorke Peninsula, Stansbury gives shore-based crabbers two straightforward options: rake the sheltered shallows of Oyster Bay when the water is low enough to work comfortably, or use a legal hoop or drop net from Stansbury Jetty. This page brings the local spots, seasonal timing and current South Australian Blue Swimmer Crab rules together in one place.
Blue Swimmer Crabs are part of the classic Yorke Peninsula summer experience, and Stansbury is one of the most practical towns for trying two shore-based methods without needing a boat. Its sheltered Oyster Bay setting on Gulf St Vincent gives you a choice between active raking in shallow water and stationary netting from the jetty.
The important part is matching the method to the conditions. Low water helps when you are trying to reach and search the shallow flats with a rake, while jetty netting is less dependent on exposing the flats and more dependent on keeping a legal net fishing cleanly. Whichever method you choose, measure every crab as soon as it is caught, use legal bait and keep the daily limits in mind from the start.
Stansbury lets you switch between raking the Oyster Bay shallows and using legal hoop or drop nets from the jetty. That makes it useful for visitors who want a Yorke Peninsula crabbing session without planning the whole trip around launching a boat.
Rake the flats or stay dry on the jettyStansbury sits on the eastern side of Yorke Peninsula on Gulf St Vincent. Its gently shelving foreshore, sandy shallows and seagrass edges suit the habitat and methods commonly associated with Blue Swimmer Crab fishing.
Useful combination: shallow access + a town jettyIf you are staying in Stansbury, you can choose a shore session, jetty session or launch from the all-tide boat ramp without moving to another town. That flexibility is the main reason Stansbury deserves its own place within the wider Yorke Peninsula crabbing picture.
Best advantage: method choice, not a promised catch
Walk accessible shallow ground with a legal crab rake and watch the sandy and seagrass edges carefully. This is the classic hands-on option when the tide and wind make wading comfortable.
Best fit: calm water around low tide
Lower legal nets from the jetty with fish-based bait, allow crabs time to find the bait, then retrieve the net vertically and check the catch immediately.
Best fit: visitors who prefer the jetty
Stansbury also has an all-tide boat ramp with boarding access, so boat-based crabbing can be added to a stay without moving to another town. A launch permit or ticket is required; a boat is useful, but it is not necessary for a worthwhile Stansbury crabbing session.
Best fit: anglers already launching locallyThe gently shelving water along Stansbury's foreshore is the obvious starting point for a rake. Low water gives easier access to the shallow ground, while calm conditions make it easier to see where sand, weed and bottom texture change.
The town jetty is the simplest option if you want to crab without wading. Local visitor information specifically identifies Blue Swimmer Crabs as a warmer-month catch from Stansbury Jetty.
Offshore sand channels around the submerged Stansbury spit are a boat-based option for Blue Swimmer Crab drop-netting during the warmer months. This is different from raking the town foreshore: water is deeper, conditions are more exposed and you should treat it as a boating session rather than a shallow-water walk.
Stansbury crabbing is less about finding one exact metre of shoreline and more about choosing usable shallow ground for raking or setting a legal net correctly from the jetty. If the foreshore is windy and difficult to see through, the jetty may be the better choice; if the flats are calm and accessible, raking makes more sense.
Stansbury's own visitor information describes Blue Swimmer Crabs as a warmer-month catch. Across Yorke Peninsula, October through April is commonly treated as the main crabbing window, with summer the clearest period to build a Stansbury trip around. Spring and early autumn can also produce, but crabbing is still variable: one good tide does not guarantee a catch.
Summer is the obvious period to build a Stansbury trip around Blue Swimmer Crabs.
Warm coastal water can keep crabbing worthwhile after the main holiday peak.
Crab activity generally improves as the eastern gulf warms, leading into the stronger summer window.
Do not plan a winter Stansbury trip around crabbing alone; the town has stronger cold-season fishing options.
Low water is the useful starting point. It makes the shallow eastern-gulf flats easier to reach and search with a rake. You do not need to chase the absolute lowest tide: comfortable water depth, clear visibility and manageable wind are more important than forcing a session into poor conditions.
Jetty netting is different. You are not trying to expose shallow ground, so there is no single universal tide answer. Focus on keeping the net sitting correctly, avoiding excessive current and managing ropes safely around other people.
Crabbing depends on more than the tide. Check wind, water clarity and any current South Australian fishing or coastal notices before setting out. Monitoring continues after the 2025–26 Karenia algal bloom; avoid abnormally foamy or discoloured water and follow current health or fishing advice if local conditions change.
For a simple decision on the day: clear water, manageable wind and a method that suits the tide are more useful than forcing a session because the calendar says it is crab season.
Measure across the carapace from the base of one of the largest side spines to the corresponding point on the other side.
The current recreational personal limit for Blue Swimmer Crabs in Gulf St Vincent is 20 per person per day.
The current Gulf St Vincent recreational boat limit is 60 when three or more people are fishing from the boat. With one or two fishers, each person's bag limit applies.
Crabs must be measured as soon as they are caught. Return undersized crabs to the water immediately.
Females carrying external eggs are totally protected and must be returned to the water immediately.
Blue Swimmer Crab and Sand Crab numbers are subject to combined limits. Sand Crabs also have their own lower Gulf St Vincent limit, so do not assume you can take a full limit of each species.
Protected females: any Blue Swimmer Crab or Sand Crab carrying external eggs must be returned to the water immediately.
Bring a legal crab rake, measuring gauge, bucket or crab trolley, closed footwear, sun protection and drinking water. Polarised sunglasses can make shallow-water visibility easier.
Most important: gauge + closed footwearBring compliant drop or hoop nets, suitable rope, fish-based bait, a measuring gauge, bucket and gloves or tongs. Keep ropes organised so they do not create a problem for other jetty users.
Most important: legal net + legal baitCarry the measuring device where you can reach it immediately. Measure first, keep second. Keep count from the first legal crab rather than trying to reconstruct your catch later.
Most important: measure and count as you goNo — not in hoop or drop nets in marine waters. Current South Australian rules allow fish or fish-based products in these nets and prohibit meat, chicken and other poultry. Old forum advice suggesting chicken should not be followed.
A legal drop net has a maximum hoop diameter of 107 cm and maximum depth of 92 cm. Up to three drop nets per person are permitted.
No registration required; marking rules still applyHoop nets are not the same as drop nets. Up to 10 may be used when no other fishing device is being used; lower limits apply when combining gear.
If mixing hoop and drop nets, combined total: 3South Australia lists crab traps as illegal fishing gear. Use permitted crab rakes, hoop nets or drop nets that meet the current specifications.
Legal device choice matters as much as catch limitsStart where the water is shallow enough to move comfortably and visibility is reasonable. Walk slowly and watch the sand, weed edges and small changes in bottom texture rather than covering ground as fast as possible. When you locate a crab, keep the rake under control and bring the crab clear of your feet before handling it. Measure it immediately and release it straight away if it is undersized or carrying external eggs.
Good raking is deliberate, not fastSecure legal fish-based bait in the net, lower it carefully so it settles flat, and give crabs time to approach. When retrieving, lift smoothly and as vertically as practical so crabs are less likely to escape over the edge. Check the catch, measure every crab immediately and return anything that cannot legally be kept before setting the net again.
Flat on the bottom · smooth vertical retrieveBlue Swimmer Crabs can grip hard. Use the rake, suitable tongs or careful handling rather than reaching between the claws. Keep retained crabs shaded and managed appropriately, and do not leave undersized or protected crabs sitting in a bucket while you continue fishing. Release them immediately where they were caught.
Measure first · handle calmly · release quickly
For raking, choose a calm lower-water window. If visibility or wading conditions look poor, consider the jetty instead.
Decide before leaving whether you are raking the shallows or carrying legal nets to the jetty. Pack for that method rather than everything at once.
Do not bury your measuring device at the bottom of the gear bag. Every crab needs to be checked as soon as it is caught.
If you are using hoop or drop nets, take fish or fish-based bait — not chicken, poultry or other meat.
Return undersized crabs and any female carrying external eggs to the water immediately.
The legal limit is a maximum, not a target. Keep count and stop when you have enough for your needs.
Yes. Stansbury is a recognised Yorke Peninsula Blue Swimmer Crab location where crabs can be raked from the shallows or netted from the jetty or a boat in season.
The shallow water along the Stansbury foreshore in Oyster Bay is the main shore-based raking area. Lower water makes the flats easier to access.
Yes. Local Stansbury visitor information specifically identifies Blue Swimmer Crabs as a warmer-month catch from the jetty.
The warmer months are the main season. Summer is the strongest visitor window, with spring and early autumn also worth considering when conditions are suitable.
Low water is the useful starting point because it gives easier access to shallow ground. Calm water, safe depth and good visibility matter more than chasing the absolute lowest tide.
The current minimum legal size is 11 cm across the carapace, measured from the base of the largest side spines.
The current Gulf St Vincent recreational limit is 20 per person per day. A boat limit of 60 applies when three or more people are fishing from the boat; with one or two fishers, each person's bag limit applies. Combined Blue Swimmer Crab and Sand Crab rules also apply.
No. In South Australian marine waters, hoop and drop nets may use fish or fish-based products, but not meat, chicken or other poultry.
Up to three legal drop nets per person are permitted. If you combine hoop nets and drop nets, the combined total is limited to three at the same time.
Yes. That is one of Stansbury's main advantages for a Yorke Peninsula crabbing trip: you can rake accessible Oyster Bay shallows or use legal hoop or drop nets from Stansbury Jetty without launching a boat.
Yes if convenience and method choice matter. Stansbury combines shallow-water raking, jetty netting and an all-tide boat ramp in the same town. Other Yorke Peninsula locations can also produce Blue Swimmer Crabs, but Stansbury is particularly practical for visitors who want several options close together.
Do not measure or count it as though it were automatically a Blue Swimmer Crab. Sand Crabs have a 10 cm minimum size in South Australia and a lower Gulf St Vincent species limit, while combined crab limits also apply.
No recreational fishing licence is required for marine fishing in South Australia. You still have to follow the current size, bag, boat, gear, bait and closure rules that apply to the place and method you are using.
Yes. Check current coastal and fishing notices before you go, especially after periods of unusual water colour, foam or marine-life impacts. If the water looks abnormal, do not rely on season or tide alone—follow the latest South Australian health and fishing advice.
