As an Aussie shooter I think your assessment is very good.
When I entered the sport in the early 70's shooters were mainly shooting Winchester 94's, customised Lee Enfield's, Model 70 Winchesters, Model 700 Remingtons, Czech BRNO centre fire rifles.
Shotguns tended to be largely Spanish imports with Japanese Miroku, Winchester and Remington pumps and semi autos .
Favourite rimfire were the Anschutz (if you could afford it), Winchester 9422 (ditto), Ruger 10/22, Winchester 320 or BRNO.
America lost its hold on the market as the American gun companies started being run by accountants rather than men who shared the passion, and with an inability to be as innovative as we had come to expect the American gun industry to be. Tragically if one looks at Winchester's last catalogue before they went broke, they had learned their lesson- but too late.
Today favourite rifles in shops would be the Tikka T3 (by far, though the Sauer 101 and Mauser M18 are gaining ground), BRNO 452 /455, the Italians and Turks and Miroku / Browning control the shotgun market.
I also see quite a few Savage and Ruger centre fire and rimfire rifles about.
