‘Save our foreshore Quinns Beach’ Facebook group co-founder Nat Sangalli said those attending included Fred Stubbs’ daughter Carolyn.
Revisiting the park during finer weather on Sunday, Mrs Sangalli said children loved the upgraded park.
‘Sunday was the best reward, sitting there and watching the kids play,’ she said.
Wanneroo Mayor Tracey Roberts highlighted the partnership established between the community and the City, and the work by contractor Curnow Group.
‘It seems so appropriate that we lost the park in a storm and we are reopening it in a storm,’ she said.
‘It was a low key opening but lots of emotion because everyone was so thankful that the park was there.’
Mrs Sangalli said she was grateful to all those who had supported the campaign started almost a year ago by herself, Kelly Keogh and Sarah Hombsch when storms caused severe erosion at the park.
‘It’s not over and people can sign a petition for long-term erosion funding,’ she said.
The petition is at Salty’s Caf� opposite the park.
Eric Coates made a miniature bulldozer mounted on a plaque for Curnow Group to show residents’ appreciation for their work, done with waves often lapping their machinery.
