Qantas doesn't have a Head Office - that's way too 2000's - they have a Campus.
The centre of productivity where the heads of departments such as Basket Weaving, Story Telling and Workplace Experience Coordination regularly gather, is called the Street.
At the head of the Street is the open space where 'Town Halls' are broadcast to the masses by the Even Greater Heads.
At least I think that's what he's talking about…...
If you are seeking employment with Qantas it's important that you understand this
type of shi.. motivational facilitation language. (Which is why current Pilots don't understand it!)
