Pinta Bay is on the southern shore of Jerusalem Bay, an arm of Cowan Creek. It is shown as Trafalgar Bay in the 1950s by Burgess. Pinta is possibly an older name as there is a Pinta Ridge above the bay. On the other hand, there could have been someone camped there or a vessel moored, when the news arrived of Nelson’s victory over the French. It could possibly be an Aboriginal name: Endacott gives the meaning as bamboo spear.
