This Red Post is in Anderson on the road from Dorchester to Wimborne. It dates back to when prisoners who were being sent to Australia had to walk to the port of embarkation. The signs wee pained red to make it easy for the escorting soldiers to follow. Near here a farm was used by the authorities which became known as Botany Bay Farm. The name 'Botany Bay' is now used by both a pub and petrol station near by.
