Just checked pc6.com (link posted by Mozzie) and VH-ZCZ was sold to Canada in the mid 90's and was resold and is now based in Rome.
Looks like there's only 1 left in Australia which is flyable VH-OWB at the Army Aviation Museum.
There was a lot of Porters in Indonesia operated by Merpati and the Dept of Agriculture , I tried to track down any unflyable Porters here but the Merpati airframes and spares were sold or scrapped years ago and the Agriculture Porters I am told what was left of them was purchased by Susi Air for spares a couple of years ago. I was looking for the Dept of Ag Porters as recently as 2 months ago and went up to Kalijati Air Base specifically to see for myself whether they still existed.
The STOL performance of these aircraft is incredible , I landed at Lower Light one day with no headwind with just me on board dragging it in on finals just above stall and then used reverse after touch down , we paced out the tyre tracks and it was approx 85 metres.
