More than 20 Fire and Rescue NSW trucks are currently responding to the blaze.
It is not known at this stage if anyone was hurt, but a Fire and Rescue NSW spokesperson said they “imagined” people were evacuated from the structure.
Paramedics arrived about 2.30pm and are currently investigating whether anyone requires treatment.
There is a risk the fire may spread to other structures, the Fire and Rescue NSW spokesperson said.
Footage of the fire shows mass amounts of smoke billowing from the structure while planes continue to fly past.
“That looks bad, I hope everybody got out,” a witness can be heard saying in a video obtained by 7NEWS.
“All that water he just put on there doesn’t look like it did anything.”
