John Riggall is adamant newly formed community group Protect Our Parks does not want to see the end of skydiving in Wollongong.

But he said the group was left with little choice but to take legal action against Wollongong City Council and Skydive the Beach in a bid to stop the firm building its new headquarters in Stuart Park.

Protect Our Parks - an incorporated group of about a dozen Wollongong members - lodged a summons with the NSW Land and Environment Court on Thursday, challenging the council's decision to grant permission for the new building. The group has named the council, the company and planners Martin Morris and Jones Pty Ltd as respondents to its claim, which states the "demolition of an existing building and the erection and use of a new building for Skydive the Beach in Stuart Park North Wollongong is invalid".

"We reckon the land the community has owned for 130 years shouldn't be given away. We have a right to use what is the best used park between the Royal National Park and the Victorian border," Mr Riggall said.

"We are not trying to get rid of skydiving out of Wollongong. We recognise it is a business that is very successful. All they [Skydive the Beach] have to do is use the land they are already using up the road [Dalton Park], instead of using Stuart Park."

The debate about the company's use of Stuart Oark - which has been a skydiving landing site for nearly 20 years - was sparked by plans to build the new headquarters and has raged in the community and council chambers for months.

In April, councillors voted 8-4 to negotiate exclusively with the multimillion-dollar company to work out the terms of a land lease and drop-zone licences in Stuart Park. The council granted consent for the Skydive the Beach building in March.

Mr Riggall said the community group was made up of residents from Wollongong and surrounding suburbs, who would be funding the legal challenge against the council out of their own pockets.

Perhaps the most high-profile member of the group is independent Wollongong councillor Vicki Curran, who last month claimed the council was at risk of a legal challenge over its decision to deal directly with the company. At a council meeting, she unsuccessfully asked for the council to seek senior legal advice on the decision.

A council spokesperson said they would not comment as the matter was before the Land and Environment Court. Likewise, Skydive the Beach would not comment.
