A 41-year-old man is recovering in hospital after being attacked by a white pointer shark near Walpole, on Western Australia's South Coast.

Michael Bedford was treated for deep wounds to his right knee and shock after the attack which happened at Conspicuous Cliffs 15 kilometres east of Walpole yesterday afternoon.

Mr Bedford was rescued by a fellow surfer and a group of local fishermen who were able to tie a tourniquet around his leg before the ambulance arrived.
