A man has died on a tennis court in the southern suburbs of Wollongong on Thursday morning.
He was found at Berkeley Sports Club on Wilkinson St after a concern for welfare report was made to police about 7.40am.
NSW Police officers performed CPR but the man died at the scene.
A nearby resident told the Illawarra Mercury they saw a woman driver pull up to the tennis courts just before police arrived, and believes she was the person who made the triple-0 call.
