Apparently the Aussies tried to get Troy PAR rifles after their 1996 assalt rifle ban but the police and customs said they were just the same as AR-15's and would not approve any import permits. So about 3 different manufacturers in Australia started making their own versions and this is just one of the 3 most popular local production models.

Pump action Remington sporting rifles also are very popular down there with their deer and pig hunters.
