Thanks P2, getting that in a post was beyond my feeble cyber skills.
one quote stuck in my mind:

"But in practice AOPA members had seen few practical gains from ADS-B, which cost Mr De Stoop $75,000 to install per aircraft and other owners as much as $120,000 per plane.

The problem, he said, is that since they are often the first worldwide to install ADS-B, Australian owners are having to pay for specialised “first of type” engineering."

The inconvenient truth is having spent all that money, and I know one or two have spent a lot more, if you need to dispose of your aircraft, and considering the market in Australia for these is about as minuscule as the minister, you'll have to spend it all again to have it removed. See, because our world leading maintenance reg's are not recognised by anyone else in the world Australian EO's just ain't Kosher.

ASA and CAsA's brain fart to lead the world gets you coming and gets you going.

No wonder the GA industry is in its death thro's
