Following up on when the Adelaide Plaza Premium lounge is to be licensed for alcohol, I found the following info on cbs.sa.gov.au:
"Plaza Premium Lounge Australia Pty Ltd has applied to the licensing authority for the grant of a restaurant and catering licence in respect of premises to be situated at Terminal 1,
International Departures, Sir Richard William Avenue, Adelaide Airport SA 5950 to be known as Plaza Premium Lounge Adelaide.
The following authorised hours for the consumption of liquor on the licensed premises
are sought by this application:
Monday 12:00am to midnight
Tuesday 12:00am to midnight
Wednesday 12:00am to midnight
Thursday 12:00am to midnight
Friday 12:00am to midnight
Saturday 12:00am to midnight
Sunday 12:00am to midnight
Determination date is 28 March, so my guess is theyll extend hours and start serving alcohol shortly after that is granted.
