Just let you know about one small trick to minimise the revenue CASA receives. IF anyone has to get an Aircraft Endorsement put on their licence do not go and get CASA to process the paperwork. Get the "Sticky Label" issued by someone in industry (i.e. School, CFI, ATO etc).
Having worked in a CASA office and had people coming through the door wanting to submit Aircraft Endorsement applications, I would hint this to them, and they would often save them selves quite a lot of money. Let’s just say this didn’t make me very popular with our office manager.
Pm if you want to know more!
