Thanx for the response so far
If I read it correctly then there are currently staff shortages , particularly at Melbourne.
This could get worse by mid year due to pending ATCO retirements and reduction in operational staff on medical grounds.
There is currently an Ab-initio ATCO recruiting drive to address this shortfall but this may not be enough.
There are possibly other controllers leaving/thinking of leaving due to current working conditions.
Airservices are currently not recruiting "foreign" controllers regardless of their resident status.
PS - Whats ASG?
