The T3 Qantas Domestic terminal is apparently not affected. We picked that up before we opened the terminal this morning.
Sydney Airport has begun processing passengers after it came to a standstill on Friday morning following "technical issues" that affected two of its terminals.
Some passengers are being re-screened, and a number of worldwide flights will be delayed.
'Virgin Australia is working to minimise any disruption to passengers caused by the earlier issues and to reaccommodate any affected passengers.
"We will start some manual processing so flights can start to move".
The incident resulted in the entire departure lounge at the global terminal at one point being cordoned off, with security searching through plant boxes, bins and under furniture. We're working to resolve this technical issue as soon as possible.
"We're advising passengers and visitors to avoid T1 and T2 until further notice", a Tweet from Sydney Airport said at 6:08am.
A spokeswoman for Brisbane Airport told the Courier Mail security screens were closed for 30 minutes after the breach.
"There may be some delays as a result, however passengers are advised to arrive at the airport as planned for their upcoming Virgin Australia flights".
Australian Federal Police officers are investigating the matter.
