A baby humpback whale carcass has washed up on Greenhills Beach in Cronulla, in Sydney’s south, according to multiple reports. The whale is described as a young humpback, and its carcass is found on the shoreline of the beach. While the reports focus on the discovery and location, they do not provide additional verified details about the cause of death or the whale’s health condition beyond describing it as a baby humpback. Local authorities and environmental or marine response services are typically involved in incidents like this, but the supplied accounts do not specify which agencies are responding or what immediate steps are being taken. The reports agree on the key points that the animal is a humpback whale and that it is found on Greenhills Beach in Cronulla. The incident is therefore presented primarily as a marine wildlife discovery, with further information not included in the provided source summaries.
