This comes from a book titled "Buses & Trams Of Australia's Government & Municipal Operators." This book has info on every operator in Australia.(https://www.actbus.net/forum/proxy.php?request=http%3A%2F%2Fi550.photobucket.com%2Falbums%2Fii421%2FJulianHamstead%2FIMG-1.jpg&hash=6e8ca0f63b18a78a71fe349e2031389b8f2efa3d)[font='ms shell dlg'](https://www.actbus.net/forum/proxy.php?request=http%3A%2F%2Fi550.photobucket.com%2Falbums%2Fii421%2FJulianHamstead%2FIMG_0002.jpg&hash=7cd2d37df6ccbbad9fbbf48b65d72676338b1380)[/font][font='ms shell dlg'](https://www.actbus.net/forum/proxy.php?request=http%3A%2F%2Fi550.photobucket.com%2Falbums%2Fii421%2FJulianHamstead%2FIMG_0003-1.jpg&hash=d17418fed147709a984b456bc273231adafed5a2)[/font]
wow, that's a great find! You've stated it includes info on every operator in Australia - I think you'll find it would be the Government operated services only.
I have this book, not a bad publication, though it only has half of the Mercs delivered at the time of printing.
I have a similar book, which details ACTIONs Fleet around the same time as this one. It's under the History section as '1983 Fleet'
