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.

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.

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.

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.

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 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.

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.

The coral Leptoseris is living 410 feet (125 meters) below the ocean's surface, a discovery that expedition leader Pim Bongaerts of the University of Queensland called "mind-blowing."

Bongaerts and his colleagues received funding from insurer the Catlin Group Limited to explore the Great Barrier Reef as part of an effort to understand how climate change is altering the oceans.
