JETS officials have rejected approaches from parties inquiring about the prospect of buying Newcastle's A-League franchise and relocating it.
Consortiums from Canberra and the Gold Coast have expressed interest this week in joining the A-League, whether that be as part of an expanded competition or by replacing existing teams.
The Central Coast Mariners appear the most vulnerable target, given that owner Mike Charlesworth announced earlier this month his intention to either sell the club or, in the worst-case scenario, hand his licence back to Football Federation Australia.
While staying in Gosford is the preferred option, Mariners CEO Shaun Mielekamp admitted that alternatives would be "looked at".
The Jets are also on the market after it was revealed in May last year that owner Martin Lee would consider selling if the right offer came along. But chief executive Lawrie McKinna said relocating the franchise would not be considered.
"We're not interested in that at all," McKinna said.
"We've been asked over the last month. We've had agents ask if we'd be interested in taking the club away. They said there were a couple of options.
"I didn't even ask where they were. I just said we have no interest in that."
McKinna had no doubt that Newcastle, which is one of seven clubs still surviving from the A-League's foundation season, was capable of supporting a viable franchise and that there was no need to consider relocation.
"Even this season, we've got 10,500 members, and that was in a disappointing season, given that we didn't make the finals," he said.
While the Mariners have struggled in recent seasons, collecting the past three wooden spoon, McKinna was hopeful they too would remain in their current location.
"I'd like them to still be on the Central Coast," he said.
"We need them there for the derby game."
McKinna said that while Newcastle missed out on the play-offs for the second consecutive year, their revival under new coach Carl Robinson augured well for next season.
After Robinson was appointed to replace Ernie Merrick in February, the Jets finished the season with seven wins and three draws in their last 11 games to eventually finish eighth, three points behind the top six.
During those 11 games, they were the best-performed team in the A-League.
"It's been a huge turnaround," McKinna said.
"We beat Sydney and we beat Melbourne City, who are both in the grand final.
"We beat Wellington 3-0 in our last game, and they finished third on the ladder.
"The way the boys finished the season is a credit to everyone, and now it's important that we build on that for next season."
The Jets are now waiting for confirmation of when next season will kick off and what salary cap they will have to work within.
McKinna said until those details were finalised, the club would not be approaching any new players.
A handful of first-team regulars, including skipper Nigel Boogaard and Panamanian striker Abdiel Arroyo, are off contract but the Jets have expressed interest in retaining them.
