THE rest of the tennis world is on notice - don't mix with the Staunton siblings.
Despite registering at the last minute, brother Glenn and sister Lana have returned from the World Masters Games in Sydney with four gold medals.
Impressive. Very impressive.
Lana - reportedly the youngest tennis competitor at this year's Masters aged just 33 - took out the ladies' singles last Sunday against players from all over the world winning the final 6-0, 6-0.
She backed up later in the week, teaming up with Kellyville entrant Isis Dalton to win the ladies' doubles 7-5, 6-4.
But it was the third gold medal that was the sweetest.
Lana coupled with brother Glenn to win the mixed doubles with an impressive 6-0, 6-0 scoreline.
Both players have plenty of accolades to their names but this was the first time either had competed at a World Masters Games.
They didn't even know the event was on until being advised by someone at the Ulladulla Leisure Centre and registered on the last possible day.
Glenn was unable to compete in the entire Masters because of local commitments to school holiday tennis camps.
But with holiday commitments out of the way it was off to Sydney and a shot at the gold.
The Stauntons impressed plenty of people on their way to the winners' dias.
Glenn's 210km/h serves caught many of his opponents by surprise while Lana's overall form earned her an invitation to compete nationally for Australia at veteran's level - when she turns old enough.
And both have been invited to Italy in four years' time to defend their titles.
Glenn, Lana and sister Kim have all competed at an elite level over many years thanks to the dedication of their parents Dennis and Shirley.
Shirley assures the Times that Glenn's serves at the Masters were the quickest that she had ever seen and that some opponents had jumped out of the way of his return shots.
