40 Evacuated at YSSY

[Trevor Sinclair]

I've received this from AAP:

Dozens of people have been evacuated from Sydney Airport after a possible fuel spill. Emergency services were called to the airport's domestic terminal on Wednesday morning following reports of a spill, a Fire and Rescue NSW spokesman said. An exclusion zone was set up and around 40 people evacuated.

There are no suspicious circumstances, the spokesman said.
Investigations are continuing.

Does anyone have further details as to whether this is T2 or T3 or what the cause was?
