I have joined a RA school in Darwin called Top End Flying club.
They train in a JABIRU 230 and /or TACNAM. $230/hr when paying in blocks of 5 hrs
It has 4 instructors 1 of which is full time
It's a good way to build up hours if nothing else

As mentioned before AV8 is closed down and Darwin Flying Schools number is disconnected
