Hi Peter - very late! No, there is no Australian link with the Kempsey group of Tolhursts and mine - at least in Australia. Of that I am sure. Mine were 4 brothers who came out between 1841 and 1865. There is also another group who seemed focused on the Kemspey area, and another in the Melbourne area. As far as I can see there is no connection in Australia between the 3 groups. In England I can't say as I cannot get further back that the aforementioned Thomas Tolhurst and Catharine Cornelius... I wish!
