I'm happy to see any thing that rids the sky of some of the pitiful excuses for aircraft that I have had to fly. I've had bits fall off aircraft, seen feet through wing walks, landing gear legs falling off. Anything that sits out in the open for 20+ years will be riddled with corrosion.
However the state of GA in Oz merely reflects the state of the country, one that is in decay. Industry in Oz has all but gone, a government that punitively taxes any sort of endeavour. The government harps on about the cost of the road toll, but slugs people with GST if they buy a new (safer) car, and for anyone who works hard so they can by something nice, the government slugs you with a punitive "luxury" car tax thank you very much.
We need tax breaks to allow is to buy new aircraft, accelerated depreciation, a cleanup of the regulatory system to make the costs of compliance less. We need a population that is less interested in sitting on its arse waiting for Centrelink payments.
