Went to the beach yesterday!

Just joking..these big fellow, some 15-30 feet long live mostly in Australian's northern estuaries. However, they really do use ocean currents and surf to travel from their estuary homes as far north as Papua New Guinea and Indonesia where they bred and then return home to the comfort of their river banks.
