Community members can celebrate the completion of the park, on the corner of Jarrahdale Road and Munro Street, at the informal get-together from noon until 3pm.
The Shire is organising a sausage sizzle.
Other activities include a clinic and demonstration from Skate Australia.
‘I know this has been a long-time coming for the community, and there have been many who have worked tirelessly to lobby for the skate park,’ Shire president Keith Ellis said.
‘Special mention for Melissa Matheson and other members of the Jarrahdale Community Association.’
Cr Ellis also thanked Lotterywest for supporting the project.
