The club has almost doubled to 178 members after adding new social and competition tennis events, a "Fit 'N Hit' fitness class and a structured coaching program for juniors and adults.

Club coach Geoff Carter said there is a real buzz about tennis in Bonny Hills as players return and youngsters join the club.

"We have also seen a number of 'return to the sport' adults join the club and become very enthusiastic again about the sport they once loved," he said.

"We knew that the potential was there, and now we have over 20 new juniors attending social, playing competition tennis and being coached weekly.

Club president Joan Evelyn, who has been in the top job for 14 of the club's 40 years, said she has seen a recent rise in interest with the acceptance of Active Kids vouchers for their coaching programs.

"We wanted to make tennis enjoyable, accessible and affordable for a wider range of people," she said.

"Tennis is not all about competitions, it is a wonderful opportunity for families to have fun together and for people to make new friends."

Mrs Evelyn said the club has also been given Hot Shots Community Play provider status and is considering introducing mini-tennis to make tennis more accessible for older adults.

"The increase in membership and court utilisation has put the spotlight on the club's infrastructure. Members have lovingly maintained the clubhouse and surrounds however the courts themselves are well past their use by date and urgently need resurfacing," she said.

"We are well outside the guidelines set out for periods between resurfacing. Because of our close proximity to the bushland, the court subsurface has been affected by tree roots and the playing surface itself is become worn and uneven."

Mrs Evelyn said the cost to replace the court surface and undertake the repair work is about $80,000. Members are applying for grants to fund the work within the next 12 to 18 months.
