Wilson's Promontory

Wilson’s Promontory, the most southerly point of the Australian mainland, is about 250 km south-east of Melbourne. It was originally part of the granite ridge connecting Tasmania to the mainland. Rising sea levels after the last glacial period, ten thousand years ago, submerged much of the ridge, isolating mountaintops as islands. Wilson’s Promontory was reunited with the mainland as blown sand accumulated between islands, forming the low Yanakie isthmus.
