If it's in a "Royal Australian Mint" roll, then the mint is Canberra, with 100% certainty. Melbourne and Perth coins were not rolled in RAM rolls, since those mints were never part of the "Royal Australian Mint".
I believe coins from the branch mints were shipped in bulk drums to the local Reserve Bank branch, and such coins (if rolled) would have been rolled in Reserve Bank wrappers, alongside with and perhaps mixed up with coins the Bank received from circulation for re-rolling.
The Mint still had manual inspection of coins back then; perhaps the checker saw something suspicious, picked it up to check it, said "No, it's good", and put it back. Or maybe it fell out of the bucket or conveyor belt and someone picked it up off the floor and put it back. Mint workers on the circulation coin floor don't wear gloves.

What's interesting is one of the coins that fell out has a distinct fingerprint on it, despite all coins being choice uncirculated. Someone at the mint in 1966 picked it up.
