Adelaide Metro Dive SItes

Site Name





Glenelg Blocks

34 58 406 S

138 30 494 E

5 m

The Blocks is a series of cement blocks visible at low tide and located 1/2 a kilometre from shore in 6m of water. The blocks were used as a mooring system for early ships coming to Adelaide. Access is by boat from West Beach boat ramp. It is an easy dive with plenty of area to cover. This is an excellent muck dive and wobbegong sharks are almost always found at the site.

Broken Bottom

34 57 701 S

138 28 923 E

11 m

Broken bottom is again part of the old shore line and consists of a series of naturally formed rock piles spread over a large area 2kms north west of Glenelg in l0m of water. Access is by boat from the West Beach boat ramp. Fish life is sparse to prolific with no set pattern. If fish life is sparse you can investigate the rock piles, sea tulips and razor shells. The colours of the sponges and flora is exceptional. At other times the whole dive can be taken up swimming amongst vast schools of sea pike and silver drummer. Many spider crabs inhabit this area and occasional a rays and flat heads may be found.

Glenelg Barge

34 58 702 S

138 26 447 E

18 m

The Glenelg Barge is a hopper barge used by the South Australian (Glenelg Dredge) to take the silt dredged up from the Port River and dump it further out to sea. She was sunk in 1984 as an artificial reef and lies in 20m of water. Access is by boat from the West Beach boat ramp. A star dropper trail has been set up to enable divers to travel from the barge to the South Australian and vice versa in times of low current. The barge is a very interesting wreck with a wide variety of fish. Divers can swim its 30m length with ease. At either end there is a small opening where divers can penetrate into the work rooms. In these rooms on each side of the hoppers is the entrance to the flotation chambers and divers may peer into them. Divers may be tempted to attempt a penetration and it can be done as long as the divers are properly prepared with lines, torches etc. The entrance to each chamber is very restricted. This penetration is not recommended. The main hazards are rusting metal, silting and restricted entrances to the penetrations.

Glenelg Dredge

34 58 753 S

138 26 548 E

15 m

The 133 foot South Australian, commonly known as the dredge, was built in Holland in 1911 and sailed to Adelaide arriving in 1912. The vessel was a self propelled cutter suction dredge that was used to dredge the Port river. The South Australian ceased its working life in 1982 and scuttled in January 1985 as a recreational resource for divers and anglers. Access is by boat from West Beach boat ramp. The wreck is laying upright in 20m water with the deck area in about 15m. The site has prolific fish life and is arguably the best fish dive off the metropolitan coast.

Glenelg Tyre Reef

34 58 884 S

138 26 669 E

18 m

The Glenelg tyre reef is a series of tyre tetrahedrons, set down as an artificial reef. Set up in 1983, 5kms west of Glenelg, 500m south east of the barge in 18m of water. As a fish breeding ground it has been very successful with large quantities of whiting, bullseyes, strongies, silver dimmer, old wives and spider crabs. The main hazard is getting loose regs and gauges caught in tyre straps.

Grange Tyre Reef

34 54 895 S

138 24 062 E

18 m

Man made reef approx. 4kms offshore from West Beach. Access is by boat from the West Beach boat ramp. Made up of a series of squares of squares of old tyres laid down by the Fisheries Dept in the late 70’s. The tyres lie in 15m of water and over the years the squares have split up and spread the tyres over a large area. The dive is interesting with a wide variety of life.

Somerton Reef

34 59 184 S

138 29 266 E

6 m


Seacliff Reef

35 02 194 S

138 28 069 E

8 – 13 m

To many a diver, this site is the best local site due to the abundance of fish and its relatively shallow depth. Seacliff reef is part of the old shore line from about 10,000 years ago. It is a reef approximately 1 metre high of the sand. It travels in a north south direction and is home to literally thousands of fish, including a number of large blue devils in the metropolitan area. A whole dive can easily be taken up by sitting on the bottom feeding the fish and not moving more than a few metres. The depth of the reef varies from 12m to15m without any hazards. Access is by boat from either West Beach or O’Sullivan’s Beach boat ramp.

Stanvac Dump



The site is where surplus equipment from the oil refinery were dumped into the sea. There are trucks, pontoons, barges, kilometres of cable, and lots of other stuff, all forming quite a large and pretty artificial reef. Access is by boat from O’Sullivan’s Beach boat ramp.

Stanvac Barges

35 07 012 S

138 24 122 E

28 m

There are 3 barges at this site that were sunk in 1954, one is 163×29 and the two measure 71 x 49. At 28m this is an advanced dive and bottom time is restricted. The barges form an artificial reef with plenty of fish life and lie approximately 5kms west of Port Stanvac and rest on an otherwise sandy bottom. Access is by boat from O’Sullivan’s Beach boat ramp.

The Norma

34 49 349 S

138 25 111 E

15 m

The NORMA was a steel 4 masted iron barque of 2122 tons, measuring 278 feet, that sank in the main shipping channel of Outer Harbour in 1907 when it was rammed whilst at anchor by the Ardencraig. The day after the sinking the Jessie Darling ran over the wreck and sank on top of the Norma breaking her back. The Jessie Darling was subsequently refloated. Because of the danger to shipping, the Norma was dynamited. The wreck lies about 5kms offshore from North Haven in 14m of water and is subject to strong tidal currents. Access is by boat from North Haven boat ramp. The wreck of the Norma is spread out over quite a large area and consists of a large area of twisted metal lying on the bottom. The bow area is still recognisable and acts as a marine haven for fish. The remains are very interesting, The fish life is prolific with wobbegongs frequently seen. If diving the Norma be aware it is still in the shipping channel and it is unwise to leave your dive vessel without surface support as large ships still use the channel. A marker bouy is positioned about 25m due west of the wreck.

The John Robb

34 49 380 S

138 20 266 E

20 m

The John Robb was built in Port Adelaide in 1879 and sank during a storm around 1910 and is in the outer shipping channel to Outer Harbour, The wreck is 15kms offshore from North Haven and lies in 18m.of water. Access is by boat from the North Haven boat ramp. The wreck is now nearly completely broken up with only the bow section recognisable sticking out of the sand pointing west. The wreck is extremely difficult to locate as land marks are almost impossible to find and a reliable GPS bearing is needed. Marine life around the wreck varies from prolific to almost barren depending on the day. Visibility is generally fairly good due to the distance offshore, but it is subject to tidal currents which can be strong.

28m shipwreck about 4km west of the Dredge around 12m in length

Leather Jacket Alley

34:58:163 S

138:28:832 E



Leather Jacket Alley is approximately 2kms North west of Glenelg and is in 10m of water. Access is by boat from the West Beach boat ramp. The dive site consists of a series of naturally formed gutters inhabited by a wide variety of fish and aquatic flora including sea tulips. The fish can be hand fed and on occasions great schools of sea pike visit the area, forming a seemingly impenetrable wall of fish which is quite spectacular.


35:08:881 S

138:26:530 E


The Lumb was sunk in 1994 specifically as a dive site by the SA dive industry. She lies upright on the bottom 50m west of the Noarlunga tyre reef in 20m of water 2.5 kms west of Noarlunga jetty. Access is by boat from O’Sullivan’s Beach boat ramp. The Lumb started life as a tug working in Tasmania before being used at Port Lincoln. She was refitted as a fishing trawler and used to fish for tuna. At the end of her life she was purchased by the dive industry. She was cleaned up and holes were cut in her deck and she was sunk as a dive site. Penetrations are easy and safe as holes were cut allowing easy safe penetration. Fish life can be sparse to prolific and look out for the many nudibranchs on the wreck.

Mac’s Ground

34:58:550 S

138:27:084 E



Macs ground is a small reef 4.5kms west of Glenelg in 17m of water. Access is by boat from the West Beach boat ramp. It is part of the old shore line and is a reef approx 1m high lying in an east west direction. The reef is about 150m long and has numerous overhangs and a small cave, home to squid and cuttlefish. Other species of fish include blue devils, silver drummer, strongies, bullseyes, old wives, leather jackets and spider crabs. It s a favoured fishing ground for winter whiting. The fish life is usually prolific and tame which makes a great dive. There are no hazards.

Milkies Reef

34:59:189 S

138:27:241 E


Named after the finder who was a milkman, Milkies is a reef running north south 4.5kms south west of Glenelg in 17m of water. Access is by boat from the West Beach boat ramp. Spider crabs abound and there are numerous nudibranchs, blue devils, cuttle fish, strongies, silver drummer and the occasional crayfish. At times it is the best local dive around because of the variety of fish life. Very few divers visit this area. There are no hazards except tidal currents.

Noarlunga Tyre Reef

35:08:900 S

138:26:500 E



Noarlunga tyre reef lies 2.5 kms west of the Noarlunga jetty in 18m. Access is by boat from O’Sullivan’s Beach boat ramp. An artificial reef set up to attract fish for breeding purposes. The tyres have started to spread out across the sea floor, but the dive is still very pleasant with a lot of fish. There are no hazards.

Noarlunga Reef



The Port Noarlunga reef system is extensive and offers excellent diving and snorkelling. The reef is broken into the Northern Northern and Southern sections that run parallel to the shore with depths of around 5m on the inside , 8m on the outside and around 10m in the gap between the reef sections. The Northern section and the gap is accessible from the platform at the end of the Port Noarlunga jetty. The Southern section is accessible via a snorkel of around 100m from the beach opposite. Alternatively the reef can be accessed by boat from O’Sullivan’s Beach boat ramp. The reef abounds with numerous species of marine plants and animals. The Port Noarlunga Aquatic Trail with 12 markers starts next to seaward end of jetty and travels south along inside of reef through the gap and then north along the outside of the reef.
