Pop star Pink has thrown her support behind Sydney’s Luna Park, saying the fun fair is one of her family’s favourite places to visit when she is on tour.

The long-term future of the popular harbourside tourist attraction has been under a cloud since a Land and Environment Court ruling last month that said operators could not install new rides without seeking further development approval.

As part of a $20 million redevelopment the park’s management had hoped to install six new rides, which it believed were covered under existing approvals.

The planning dispute is the latest in a long-running battle between some local residents and operators, with Luna Park’s managing director Peter Hearne telling Fairfax Media the ruling had placed “a big question mark over the long-term viability of one of Sydney’s best known and most-loved destinations”.

With Luna Park supporters starting a campaign on Twitter under the hashtag #savelunapark, Pink’s contribution featuring her children Willow and Jameson has attracted worldwide attention.

“I hope Luna Park is around for ever and ever and ever!!!” she posted.

Luna Park attracts more than one million visitors a year, but some Sydneysiders fear that pressure from nearby apartment owners and developers could ultimately doom the attraction.

Mr Hearne said: “We have always played by the rules only to find that, now, those rules are being interpreted in a way that will place the long-term future of the park in doubt.”
