The $919,028 grant will be used to upgrade the playing surface of Macquarie Park's 11 netball courts, modify the toilet block to include disabled access and improve the clubhouse.

Hastings Valley Netball Association president Helen Miles said the grant was really a lifesaver for the sustainability of netball in the area.

"This means everything to us," she said about the grant through the ClubGRANTS category three scheme.

Registered clubs earning more than $1 million each year in gaming machine profits contribute 0.4 per cent of that revenue to the ClubGRANTS category three fund.

The state government distributes those funds.

The area's netball growth was stymied with netballers confined to seven courts, given the closure of four courts due to damage.

The association has about 1260 members drawn from across the area from six-year-olds to the 50-plus age group.

The upgrade will raise the court profile and add a concrete edge around all of the courts.

Modifications to the toilet block will add disabled access, and the clubhouse floor will be repaired and resurfaced, and a ceiling and insulation added.

Mrs Miles said the result would be a much better community facility.

"It's going to be a top class community facility in our region, and it's one we are going to be happy to invite our friends from other associations to come and play at, instead of a bit of an embarrassment," she said.

Port Macquarie MP Leslie Williams said the redevelopment was a major win for the netball community with 150 teams and 1200 players using the facility. She said the association would be able to attract more players and netball events.

Mrs Williams said the facility was also used by others the community, including children learning to ride bikes.

"We have the potential of it being utilised even more, particularly with the accessible toilet and a surface that's much kinder to those people using it," she said.

Hastings District Respite Care helped the association put together the final grant application with a philosophy of working together to grow community assets.

Mrs Miles said she could not overstate Hastings District Respite Care's help in preparing the final grant submission or thank the state government enough for making grant opportunities like these available to sporting groups.

Netball NSW general manager sport development Nikki Horton said the upgrade would be fantastic for the community and the sport of netball in the area.

Netball is the most popular sport for women and girls in Australia.

The upgrade will start this month with the work on the toilet block.

The court upgrade will start after the junior competition finishes in September.
