THE Gold Coast now boasts the largest tennis facility in Queensland, thanks to a $1.93 million expansion of the Gold Coast Seniors Tennis Club.

Club president Mike Evans says the upgrade from nine to 15 courts is a credit to the community and the tennis players in the 37-year-old club.

"We had to come up with a third of the money," he said.

"We want to introduce disabled tennis so we put in a flexi-cushion court which wheelchairs can play on."

The club is also looking forward to hosting the Australian Seniors Titles in January next year and is doing all it can to attract the World Seniors Titles.

As a mark of appreciation, all 15 courts are being used on opening day.

"Pick up a racquet or come down and borrow one of ours and have a hit," Mike said.

"It's lots of fun and you can meet new friends."

Mayor Tom Tate said the venue had already attracted major events including the Pan Pacific Masters Games, World Transplant Games and Australian University Games.

"We also recognise the importance of quality sports facilities as an economic driver. This venue is another string in our economy's racquet, supporting the Gold Coast as Australia's sporting capital," he said.

The upgrade was funded by the Gold Coast Seniors Tennis Club (GCS), Miami Tennis Club, City of Gold Coast and the State Government.

Treasurer and Minister for Sport Curtis Pitt said the State Government was proud to support grassroots sports, especially where clubs helped seniors remain fit, active and social.

The GCS also has 400 junior players coming up through the ranks.

The club is at 24 Pizzey Dr Mermaid Waters.
