Because Australians are not allowed semi-automatic guns, rifle manufacturers make some interesting bolt and pump action conversions of AR-15s, AKs and other rifles for the Australian market.
H&K produce a special version of their SL8, itself a consumer friendly version of the G36, for the Australian market called the R8. It functions as a bolt action. The rifle is not manufactured with a gas system, that is then blocked to make it single shot, as other single shot conversions have been.
Last year H&K Australia were informed that they could not longer import the R8 because it is duplicates a military rifle. They are pissed because as you can see below it barely resembles the G36. The R8 receivers and barrels were never capable of functioning as a semi-auto (or at least that is what they claim).
Earlier in the year H&K again entered into proceeding to get it reclassified.
Many thanks to Ben for sending me the documents relating to the story.
