The Erskine resident took part in the Australian Masters Athletics Championships in Adelaide last week and walked away with the Champion of Champions title after throwing a personal best against men half his age.
The title is awarded to the competitor who betters their individual throw by the greatest margin with a representative from every age group, which goes up in increments of 10 from age 30.
Mr Davis threw the 3kg hammer 34.36m to sit on top of the podium after initially throwing 32.83m in the age group event.
He also competed strongly in the javelin, discus and shot put, saying he will continue to train every day of the week, including five weight sessions and three throwing sessions.
