Giant Australian Cuttlefish

The giant Australian cuttlefish (Sepia apama) is the largest cuttlefish in the world, reaching up to half a metre in total length and weighing in at around 11kg. Solitary animals, they are found all along the coastline of the southern half of Australia—from Central Queensland on the eastern coast, right around the bottom of the continent and up to Ningaloo Reef in Western Australia.

HMAS Tobruk was retired last year after 35 years of service, including many humanitarian missions. She was launched in 1980. During her 34-year operational history, Tobruk sailed over 947,000 nautical miles (1,754,000 km; 1,090,000 mi) and was deployed on 26 major operations. HMAS Sydney was laid down and launched in 1980.

On 28 February 1943, the crew of the Catalina sent out a radio statement saying they needed to make an emergency landing. The aircraft crashed during the attempted landing and the 11 personnel on board were killed.

The wreckage was first discovered 56km south of Cairns in 35m of water by Cairns diver Kevin Coombs in 2013, but weather and planning challenges delayed the final dives to complete the investigation.

The A24-25 was part of a task force flying long‑range missions against Japanese shipping and submarines during World War Two. On 28 February 1943, Catalina A24-25 and its 11 aircrew were on a 17-hour mission to provide anti-submarine cover to a convoy heading for Milne Bay in Papua New Guinea.

Fight against crown-of-thorns starfish goes hi-tech

Developed by roboticists from Queensland University of Technology, this is the world's first robot designed to search and destroy (so to speak) the dreaded crown-of-thorns starfish (COTS). It does this by seeking them out, identifying them and then administering a lethal injection of bile salts.

Its creators, Dr Matthew Dunbabin and Dr Feras Dayoub, equipped the robot with GPS, stereoscopic cameras for depth perception, thrusters to improve stability, pitch-and-roll sensors as well as the pneumatic injection arm.

Humpback whale numbers double off Eastern Australia

very year from late April to August, humpback whales migrate north along Australia’s Pacific coast to the warm coastal waters of Queensland and the Coral Sea to mate and give birth. According to Geoffrey Ross, wildlife management officer and coordinator of the Marine Fauna Program for the NSW National Parks and Wildlife Service (NPWS) off Cape Solander south of Botany Bay, humpback whale migration periods are becoming longer annually as their numbers increase.

Australian government seeks to opt out of shark protection

The five types of shark were among 21 species of shark and ray, including sawfish, granted new protection status at a convention summit in November.

Although Australia did not object to the listings in November, it is now seeking to opt out of the commitment to cooperate with other countries to ensure the five migratory shark species do not become extinct. The expanded list is due to come into effect on 8 February.

Great Barrier Reef potato cod at risk from own friendliness

Potato cod in Queensland are at risk and their placid and curious nature appears to be playing a major part. The Great Barrier Reef Marine Park Authority (GBRMPA) is investigating reports that illegal fishing and fish 'framing' are responsible for declining potato cod numbers at the Cod Hole, a popular dive site off Lizard Island.

Western Australia implements Internet shark tracker

In a world-first, the public is getting the opportunity to assist monitoring shark movements off the Western Australia coast in a bid to reduce the number of attacks. The Department of Fisheries has updated its Sharksmart website, which will digitally map all reported shark sightings from the public, surf lifesavers and other agencies.” We want to give beachgoers the latest information so they can make informed decisions about their water use," said Lisa Clack, manager of the department's shark response unit.

The relative abundance of sharks was significantly higher in non-fished sites

Healthy reefs have more sharks

The present study examined shark distribution patterns, species-habitat associations, and marine reserve use with baited remote underwater video stations (BRUVS) along the entire Great Barrier Reef Marine Park (GBRMP) over a ten-year period.

Overall, researchers recorded 21 different shark species. The relative abundance of sharks was significantly higher in non-fished sites in the GBR Marine Park no-fishing zones relative to fished sites.

Western Australia Shark Cull Rejected

The policy allowing for the culling of any sharks longer than 3m was introduced after seven lethal shark attacks in three years off West Australian beaches. WA’s government proposed the new program in an effort to keep beachgoers safe that involved setting out baited drum lines, which consist of a large baited hook attached to a buoy and an anchor to hold it in place, in designated zones along popular beaches with the intention of killing great white sharks, bull sharks and tiger sharks who were larger than three meters.
