Yesterday's rampage by a gunman at Monash University in Melbourne heaped more pain on Australians, who remain edgy and nervous in the wake of the Bali bomb attack on October 12. The shooting, in which two people were killed and eight injured, came just a day after Australians mourned those who died in Bali at tributes and church services around the country. Australians have been watching television images of the carnage wrought by the Kuta blasts all week. To be confronted once again by pictures of distressed young people fleeing in terror and breaking down in tears seemed like a cruel form of deja vu. 'It was all a bit of a shambles,' said one university staff member. 'We were sitting in our office when a colleague from the second floor came down and said 'quick, there's a guy with a gun on the fifth or sixth floor'. We were all gobsmacked. 'Apparently one of the injured had walked down to the second floor into one of my colleagues' offices and said 'I've been shot, what do I do?' ' Other students initially thought they were under attack by a sniper, mindful of the lone gunman who is currently terrorising Washington DC. Student Rebecca Tomlinson told ABC radio: 'We were told that the sniper was on the roof of the building. I looked out the window and saw throngs of students standing on the lawn. 'Everyone was just looking at the police helicopters and no one knew what was going on. Of course it was very frightening because we had no idea whether shots were going to be coming from the roof.' Speaking in parliament, the leader of the opposition Labor Party, Simon Crean, said the sympathy of MPs went out to the victims of the shooting and their families. He said that, like the parents of those killed in Bali, there would be Australians who would 'yet again . . . have to live through the horror of innocent young people being struck down by tragedy'. Prime Minister John Howard said: 'The loss of any life in such violent circumstances is always a matter of regret, especially so when it is young.' It has been a disturbing two weeks for Australia. In addition to the Kuta bombing and yesterday's incident in Melbourne, detectives are still hunting the killer of a senior public servant who was shot dead in a lift in the middle of Adelaide last Monday. Dr Margaret Tobin, the Director of Mental Health Services in South Australia, was shot four times in the back in a contract-style killing that shocked the country. There would have been even greater outrage had her murder not been overshadowed by the Bali blasts. Yesterday's shootings also revived memories of the Port Arthur massacre in Tasmania in 1996, when 35 people were shot dead by lone gunman Martin Bryant. The massacre prompted Mr Howard to introduce tough new gun laws banning semi-automatic assault rifles. But Senator Bob Brown of the Australian Greens Party called yesterday for the legislation to be beefed up, demanding a ban on semi-automatic handguns, one of which was used in the Melbourne attack. 'There's no place for semi-automatic handguns in our community. There are 300,000 handguns in circulation and the number is increasing rapidly.'
