Cost: $99 (GST inc)

Diving Tweed Heads offers many beautiful dive sites! However, Cook Island is the dive site that stands out the most. Indeed, it has become the most popular dive site for diving Tweed Heads. Cook Island is a nature reserve situated approximately 600 metres off the coast from Fingal Head. The dive site is home to a variety of marine species, from tropical fish to the majestic grey nurse shark. Additionally, the rocky reef provides a reserve for many endangered species of cod, gropers and not to mention the large population of birds that nest on the island. Importantly, dive Cook Island any time of the year and enjoy the wonders of this perfect Open Water dive site.

Nudibranchs are another entrancing species that steal the show at Cook Island. Indeed, the site is popular among underwater photographers who come visit from around the world to test their macro skills. However, if Nudibranchs are not your thing, the turtles will also keep you entertained for the 45 minute double dive. Below are some of the major highlights that can be found while you dive Cook Island.


Cook Island was known as Turtle Island and it won’t take you long to see why! Green and Loggerheads will be the main attraction during your double dive and surface interval. During the winter months, humpback whales will keep you company during the surface interval. Further, there is also a good chance of seeing a pod of dolphins as you approach the dive site. Leopard sharks also inhabit the dive site during the warmer months of spring and summer.

Dive sites at Cook Island have an average depth of 10 metres. The water temperature ranges from a cool 19 degrees during the winter months to a comfortable 24 degrees during summer. The island also provides protection from swells or winds all year long, which makes our surface intervals one of the calmest ones.

Open Water Course Upgrade

As mentioned, Cook Island is the ideal dive site to complete your Open Water Course. Hence, the optional upgrade to the Island is offered, for the third day of the Open Water Diver Course.

Further, gaining experience from a dive boat will cap off an already amazing experience.  Mixing up between shore entry and the famous backwards roll off the boat, will have you ready to go to most of our famous dive sites. In addition, the double 40 minute dive will increase your bottom time, which will increase your experience. What a way to complete your Open Water Course!

Furthermore, your adventure will be memorable as you glide in the shallows with the famous green and loggerhead turtles. Finally, let’s finish your course with a splash, diving Cook Island in Tweed Heads.

Night Diving

It doesn’t matter how many times you dive a particular dive site, once you descend after sunset, you are entering a different world. Cook Island is no different; the turtles may be there or even the manta rays but more marine life comes out to play at night! 

You will descend on your first dive just before sunset. During the surface interval you will experience the sun disappear behind the mountains to the west with a warm cup of tea or coffee. Your second dive will be in complete darkness; only the light from your torch will allow you to gaze into the bioluminescence and the wonders of night diving.

Night speciality is not required. 

Start time is 5.00pm QLD time.

Torch hire: $20 (Must have your own torch and glow stick).

Certification is Open Water and above (If you would like to do the night dive with a diving buddy and unguided, you must hold a night speciality certification). 

9 Mile Reef

If the dive is cancelled due to the weather turning the ocean into a brown washing machine, you will be refunded.

Cook Island has something to offer to divers of all levels! While open water divers can enjoy a range of different dive sites, Nine Mile Reef, is the go to dive for the Advanced diver who is keen to do a bit more diving Tweed Heads. The dive site is located about 7 km off the coast of Fingal Heads at Tweed Heads. The top side of the reef begins at 10 metres of water and drops down to 27 metres. This dive is treated as a drift dive with a rapid descent, therefore, only divers with a minimum of 15 logged dives are permitted to dive here. Usually, the dive begins with a free descent to the bottom, and then allowing the Easterly current to drift us into the rocky shelf. Furthermore, the second dive is a shallower dive at Cook Island.


Nine Mile Reef is well known for being a little “sharky”. With that in mind, you will also see turtles, eagle rays, wobbegong and a large range of pelargic cruising by. During the colder months we venture out for the Grey Nurse sharks on the Northern wall. With any luck you may hear or even see the Humpback whales cruising above. Also, other shark species you may encounter include bull sharks, bronze whalers and the occasional reef shark.
