For 20 years Di Sanderson has been organising the Sanderson Cup at the Busselton Tennis Club with ladies teams from all over the South West.
The competition is held every Thursday for five weeks in Busselton and provides an opportunity for the ladies who play to improve their tennis often going on to play in pennants.
Di Sanderson said it is wonderful to see the women improve through the competition
"It's popular, competitive, and fun," she said.
