It has been erected by Redland City Council in Renora Street on Russell Island.
It is the first council children's facility to be constructed south of the Russell Island Ambulance Station.
The new children's park has come via the efforts of Division 5 Redland City Councillor Mark Edwards.
"Council is responding to a request from residents for such a facility.
"The point was made that there are few facilities south of the Ambulance Station on Russell Island, with most crammed into the northern sector.
"Residents, where young children and visiting grand children often frequent, put a request to council for consideration for a children's park facility," Cr Edwards told The Friendly Bay Islander.
The Renora Street area is land that had been designated by council for possible community use.
"I am pleased to say a Pocket 'Pirate' Park has been erected which contains play gym equipment including swings, slides and climbing areas with a 'pirate' theme in a large sand pit especially catering for younger children," Cr Edwards said.
The attractive area overlooks waterways to the west.
A further resident request will see a seat placed at the location for adults to observe and watch their children and, at a later date, it is hoped an electric barbecue will be added.
"The seat will be placed in the near future, however, the barbecue probably have to wait until the next financial year.
"There is a considerable waiting list for them throughout the Redlands," Cr Edwards said.
