As has been mentioned in this thread,this aircraft IS still being used!
At the time of the OP photos it was the main trainer at a school down at Donnington airfield Woodstock (Google " flight training schools Townsville Facebook" for a video of it flying and an admission of taking the young girl for a fly ) don't be fooled by the J160 in the photo,word has it that it will sit for 4 months at a time and has about 60 hours on it since 2009.
Why they don't use that J160 which is a perfectly good aircraft is anyone's guess.
I first saw this Gazelle when it showed up at a fly in at Ingham in around August 2016
As the CFI drives to fly ins there was some banter as to who was going to be silly enough to "play the student" and get in this particular Gazelle and fly the CFI's wife up ,whom apparently claims on her Facebook page, to be a pilot at the school but nobody has seen her fly solo.
This aircraft is an absolute disgrace and an insult to RAA members who are trying to do the right thing.
I am lead to believe,after having no luck in getting through to the CFI, a number of official complaints had been made to the Tech manager by people trying to give him a heads up on what is actually happening,only for the Tech manager to say a thorough investigation has been carried out and it has been sorted.
Any wonder the OP had gone public !
In my opinion a crash involving this aircraft is imminent.
I saw with my own eyes the severe corrosion on the torque tube and where the torque tube enters the aileron.The bush in the hanger supporting the torque tube where it enters the aileron is missing so there is excessive play and just asking for a flutter event !
Here is an AN warning of these very symptoms (in case link does not work have attached photos of an)

The leading edge of the left hand end of the port aileron is corroded paper thin !
Roofing screws in the doors,poor lock wiring,kinked brake lines,cracked non standard tyres,filiform and exfoliation corrosion etc etc ...
The CFI has been heard to boast the aircraft is also illegally fitted with a 100hp Rotax and not the 80
this is a 24 rego aircraft used as a trainer and should be used as an example of what's required of good airmanship to new members .At the moment it's an embarrassing insult to us all
