The Wellington Square (or Moort-ak Waadiny) redevelopment's star attraction is the 3000m2 intergenerational playground Koolangka Koolangka Waabiny, one of the biggest playgrounds in greater Perth. Meaning Children Children’s playground in Whadjuk Nyoongar, the area features nature play, a skate park, parkour activities, a flying fox, embankment slides, a pump track, waterplay and climbing towers, as well as basketball courts.
Additionally, a place of reflection is located in the north-west corner of Wellington Square to commemorate the Stolen Generations. The theme for the community playground is 'Landscape of Play' and the design is influenced by Aboriginal themes and Western Australian iconic landforms.
