Club president Andrew Dorman said corellas caused the club issues every year – but this year was significantly worse. 

“They have usually been on one or two of our back courts. That happened last year and we tolerated that and fixed it up,” he said.

“This year they have attacked our front bay, which is our best bay. It is the first time I can remember that (area) being significantly damaged.”

At this stage, Mr Dorman said the club had one court which could be used.

“All the courts have some damage on them. The corellas come and dig holes and we fill the holes, but they come back and keep going,” he said. 

The club has called out for club volunteers to scare the birds away in the morning and evening, as well as trying other ways to minimise the damage. 

“We’ve tried other methods like stringing wire across the courts. That hasn’t had an effect,” Mr Dorman said.

“We put up some cut-out black cats last year and that worked for a little while.

“Someone suggested putting tinsel on the courts, so we have asked members for any tinsel they might have.

“We are always looking for other ideas.”

The club has also contacted Horsham Rural City Council to see if they can help with the situation. 

The council’s director of planning and economic development Angela Murphy said the council was liaising with sporting groups and asking them to monitor the time of day the corellas were gathering. 

“It is important that we work together as a community to manage this issue in our city,” she said.

With the tennis season to resume soon, Mr Dorman said it was likely the club would have to find a new location for its matches. 

Corella damage has also affected other parks and recreation reserves within Horsham this summer.

Coughlin Park has been severely damaged, with the ground not able to host cricket matches for the rest of the season. 

The birds have also damaged Horsham’s Sawyer Park, with the council’s Australia Day celebrations to take place there on Friday.
