It would probably be a good idea to post this question in Dununda and Godzone.
There's pro's and con's with big v small cities. General Aviation controlled aerodromes v non controlled aerodromes.
Every one's needs are different. One school may be perfect for me but you'll hate it. Remember, the instructor can make or break your experience at a particular flight school.
I know of Aerospace Aviation, I have done an instructor rating there and several instrument rating renewals.
I am not a fan of the Tomahawk, I think the Beech Skipper is a better aircraft. The C152 is not bad as a basic trainer.
The Cherokee is good for the navigation side of training. I love the Beech Sierra but it's probably not that cost effective. (Great aeroplane to fly though and ticks all the boxes for the CPL)
Aerospace Aviation uses the venerable Partenavia for the Instrument rating. A nice easy aeroplane to fly. Good stable IR platform. Big bonus, if you intend to work in Oz, many charter companies up north use them. The Duchess is ok but I prefer the Partenavia.
