Don't need one at Parafield. And that was straight from the Airport's on site office. As a side note: if you hold a gate swipe card as those based there do for 24hr access airside and have an ASIC they will align it with your ASIC to cancel when the ASIC does. Then you need to re apply every 2 years along with the ASIC.
If you don't hold an ASIC you get a 2 year life on one anyway. They will be running CASA next!#!!
