Fingal Head is a spit on the south side of the mouth of the Tweed River which divides NSW from Qld. It is as far north as you can travel in NSW. Opposite Cook’s Island – a rocky outcrop a kilometre off-shore and one of the few landmarks to bear his name – there is a township and a still functioning lighthouse on a headland. The headland is composed of basalt, extruded in crystalline formation by the now extinct volcano that once dominated the Tweed River valley. Middens have revealed long occupancy by Indigenous Australians.
