Grey nurse sharks
The grey nurse shark Carcharias taurus is listed as endangered under the Nature Conservation Act 1992. Recent research estimates between 1800 and 2000 grey nurse sharks live along Australia’s east coast1. Wolf Rock, located just north of Double Island Point in Great Sandy Marine Park is one of only four known key aggregation sites for the grey nurse shark in Queensland2. It is the only known gestation site and the most northern known aggregation site for the species on the east Australian coast.
Grey nurse sharks are not prolific breeders. They produce only one or two pups every two years3. Because of this slow breeding rate, the grey nurse shark population will be slow to recover from past overfishing.
