The Moonan Brook Recreation Reserve recently received a $40,540 grant from the state government's Public Reserve Management Funds Program which has enabled them to revamp the popular facility.

Locals, Easter campers, Member for Upper Hunter Michael Johnsen and Upper Hunter Shire Council Deputy Mayor Maurice Collison attended on Sunday to mark the formal opening of the facility.

President of the Moonan Brook Public Reserve Terry Teague said the process of applying for a grant began four years ago.

"This particular tennis court has been in use all of my life and many years before that," Mr Teague said.

"We believe the club was formed in the early 1900s when locals got together and built the court.

"In more recent years, the younger generations have moved away due to work commitments, and preparing the court for play has become more difficult."

Mr Teague thanked Kerry London for her endless hours of work preparing applications, while also thanking John Spicer for his contribution.

He said the state government's grant had covered the cost of resurfacing the court as well as the retaining wall and a part of the new fence.

"The new fence was made possible due to a kind donation from Ray Keaton," Mr Teague added.

Upper Hunter Shire Council also contributed to the project by installing a culvert in front of the tennis court which rectified a drainage issue.

"As you can see this tennis court can't have mud and water on it, so we helped out and we are very proud to have done so," Upper Hunter Shire Council Deputy Mayor Maurice Collison said.

Member for Upper Hunter Michael Johnsen said he was happy to be able to assist in obtaining funding for the upgrade to the tennis court, which is a "vital piece of social infrastructure".

"The best community projects are driven by passionate locals," Mr Johnsen said.
