Saltwater Crocodiles are very common in certain portions of northern Queensland; the species general range extends from Rockhampton to the Torres Strait, along with the rest of northern Australia. Population sizes vary depending on the area, but it is wise to avoid swimming in any rivers or lagoons unless they are known to be safe signposted for swimming. Read warning signs carefully.
In summer months Oct-May don't swim in the ocean or estuaries without a stinger suit. They especially inhabit in shallow water near beaches.
