'Port Arthur' happened in April, 1996...
That shooting was perpetrated by a simpleton who chose a popular restaurant at a Tasmanian National Park. His primary weapon was an
AR-15 stolen the morning of the shooting from a couple known to the shooter...he killed them before going on the rampage at the 'Broad Arrow Cafe' at the national park. Most of the victims were in the restaurant and were shot at very close range, there was apparently only one exit functioning on the day of the incident. There were a few more victims shot along the 'retreat' the killer made back to the murdered couple's house, which is where he was captured.
This is the 'Port Arthur Massacre" which John Howard used to implement the ban on all semi-auto long arms (yes, including .22 rimfire) as well as all pump-action shotguns. There was massive media outpouring of grief as well as a total hatchet job on the lawful firearms owners of Australia
The records of the trial and evidence presented in this case are sealed for fifty years. Heresay reports suggest serious blunders by the Tasmanian Police in regards to both their prior treatment of the shooter (no licence) and their response at the scene of the shooting (no show). The rifle used is believed to have been surrendered in a Victorian "buyback" of semi-auto rifles earlier and traded by the Victorian Police for equipment from a Tasmanian dealer.
The current "buyback" involves only handguns, as Lock Down explained.
This stems from the killing of two Chinese students at Monash University in November of '02 by a Chinese student who was a licenced handgun owner-although there are many questions the Victorian Police decline to answer concerning the licencing of this student.
Once again, this "massacre" was used as justification by John Howard to make illegal and seize up to 80,000 handguns from licenced sporting shooters. No change for 'occupational shooters such as police and security guards. It should be added that the shooting at Monash was the ONLY incident of a registered handgun being used by a licenced owner to commit murder in Victoria since the Federation of Australia in 1901:banghead:
