Current news says all air traffic to and from SYD airport was halted whilst this apparent emergency played out. At peak time this must have been a disaster.
Minister said a minute ago "things are getting back to normal now at airport". Now 7.35pm.
Federal Transport Minister on TV just indicated the 'object' may have been a barf bag. The writing on it appears to be letters only - not words. Curious.
Reading between the lines seems like it was a stupid hoax.
