Troubridge Point is about 11 kilometres (6.8 miles) south west of Edithburgh.
It is the most easterly point of the Yorke Peninsula coast that directly adjoins Investigator Strait.
It is the termination for a pair of coastlines - one extending from Cape Spencer
in the west and the other extending from Sultana Point from the north in Gulf St Vincent.
It is the western end of the opening to Gulf St Vincent.[Wikipedia]
