Pete-
"Docter" is a family name and isn't spelled as Doctor, like a physician. Herr Docter bought the old Carl Zeiss factory in Jena, Germany, fomerly East Germany. He improved it a lot.
I own both Zeiss and Docter binoculars and have used Zeiss 'scopes. My son still does. Anyone who has not tried them is not qualified to comment on top grade optics. They, Leica, and Swarovski just blow away anything else. That said, Leupold scopes are excellent and are very good value. Leupold binoculars just aren't on par with the best Euro and Japanese brands.
Why must you shoot 'roos in the head? Is this some left-leaning Greenie law, to prevent suffering, if they must be killed at all?
What does it take to get a rifle license there, in Western Australia? I read on another board that politicians in Canberra are plotting to ban ten-shot rifles, which would encompass the Lee-Enfields! Has that scheme gained ground?
A member in Victoria said he thinks that no Australian state allows hunting with handguns. Can you carry one in WA for backup when hunting dangerous animals, if you have any, save for crocs and water buffalo? Dingos? Feral dogs? Can you hunt foxes or dingos with pistols? Can saltwater crocs be shot at all? They've increased in numbers vastly in recent years. Do they live as far to the SW as Perth?
I always enjoy your posts. Most of what I know of Australia comes from you guys on this board and from old re-runs of, Blue Heelers and, Sea Patrol.
