Humpback whales frequent Gold Coast Bay, Australia, for breeding, resting, and migration, facing vessel traffic. This study used 4319 citizen science whale sightings (2011–20) to map whale habitats. Calving pods stayed near shore, overlapping with non-calving pods further in the bay. Vessels affected up to 80% of these areas, endangering mother–calf pods. Evaluating all bay-bound vessels is suggested to safeguard the whales.

This research has described the age and growth of the endangered Maugean skate population in Macquarie Harbour, Tasmania, by applying a novel ageing technique to opportunistically collected vertebrae. The study has important implications for the assessment of the population of the Maugean skate and subsequent management decisions.
