Two hours a week of instructing and the CFI puts on another instructor!
Given as stated I am of the view that there is barely enough work for one instructor much less two more.
Two hours a week instructing probably means lots of unpaid telephone answering 'to catch those student enquiries' or other unpaid jobs like washing and cleaning etc. etc.
And then you have to go out and do a second or third job or have relations with Centrelink.
You are not going to make much flight time at this location and are being exploited with a capitol E.
Move on.
