One transformer is fully alight with a second transformer at risk.

Shellharbour Airport has been forced to close as more than a dozen firetrucks work to contain the blaze, which police say poses a risk to nearby residents.

A total of 16 trucks and 60 firefighters are battling the flames, but no injuries have been reported at this stage.

“Due to the smoke being considered toxic, affected residents are urged to stay indoors and secure all doors and windows,” a spokesperson for NSW Police said.

“It is anticipated that it may be sometime before the fire is under control.”

Fire and Rescue NSW Superintendent Adam Dewberry said Shellharbour Airport has been closed.

“We have shut down Albion Park Airport as the smoke plume is impacting the approaching aircraft,” he said.

He said the situation is evolving but so far, emergency services are unable to extinguish the blaze.

“At this stage firefighters are unable to fight the fire until the confirmation power has been shut off by the electrical authority.”
