Between the Proserpine and O’Connell River mouths is a 13 km long shoreline fronted by low beaches and backed by 2 to 3 km of mangroves, and in places up to 10 km of freshwater marsh. The entire area is part of the low, swampy delta of the Proserpine and O’Connell Rivers, with the Bruce Highway located several kilometres inland. The beaches that form the shore face east to south-east into the northern end of Repulse Bay, making them reasonably well-exposed to the Trades. Most are, however, fronted by extensive low tide bars to sand flats up to several hundred metres wide. Apart from one 4WD track out through the mangroves to New Beach, there is no vehicle access to the shore. On the south side of Thompson Creek is the irregular Letherbrook Beach (1054). This 2.2 km long beach begins inside the southern side of the river mouth. then runs along the open coast to the mouth of the O’Connell River. The beach is backed by older beach ridges and dunes up to 1 km wide. It is fronted by extensive intertidal sand flats up to 2 km wide and is bordered by the deep tidal channels of Thompson Creek and the O’Connell River. read more
