'No evidence' athletes travelling to Russia will be in danger "The Russian authorities are reassuring the international community that the security of the games are of the highest priority": Foreign Affairs Minister Julie Bishop. Australia has expressed confidence that Russian authorities can keep athletes and sports fans safe in the wake of two terrorist bombings that killed at least 30 people ahead of the Winter Olympics. Foreign Affairs Minister Julie Bishop said on Tuesday Australian officials were working closely with Russian counterparts and Olympic officials to ensure the safety of Australia's team. But the athletes face restrictions on their movements. Australian Olympic Committee president John Coates announced they are banned from training or visiting parts of Russia outside Sochi, the city where the games are to be held in just under six weeks. Deadly bomb blast: Volgograd railway station. The announcement followed two deadly bomb blasts - one in a railway station and the second on a bus - within 24 hours in the southern city of Volgograd, about 700 kilometres south-west of Sochi. The bombings are believed to be the work of Islamist separatists from the Caucasus republics of Chechnya and Dagestan. Ms Bishop said on Tuesday she had no reason to think the Russians were not up to the task of ensuring the safety of athletes and spectators. "The Russian authorities are reassuring the international community that the security of games are of the highest priority and we remain in regular and close contact with them," she said. Asked if Russian authorities were up to the job of keeping athletes and spectators safe, Ms Bishop said: "We have no evidence to the contrary." Snowboarder Nate Johnstone said he was sure the security would be tight enough to keep any threats well away from the athletes. I'm not worried. I'm sure the Russians are going to do a good job on security," he said. When I was there for the test event back in February and there was next to no one there, the security was still very tight. I couldn't even try to imagine what it'll be like come this February. But Australian Winter Olympic gold medal prospect Torah Bright says she will pull out of February's Games in Sochi if Russia's apparent terrorism problems worsen. She believes going to Russia may not be a gamble worth taking. The Department of Foreign Affairs has not increased the level of its travel warning for travel to Russia since the bomb attacks. It urges people to "exercise a high degree of caution" but does not advise them to reconsider their travel. IOC president Thomas Bach has written to Russian President Vladimir Putin. The deaths have sparked concerns over the safety of athletes and officials before the Winter Olympics. Mr Bach said he expected a safe Olympics. "This is a despicable attack on innocent people and the entire Olympic movement joins me in utterly condemning this cowardly act," he said. Our thoughts are with the loved ones of the victims. I have personally written to the President of the Russian Federation, Vladimir Putin, to express our condolences to the Russian people and our confidence in the Russian authorities to deliver safe and secure Games in Sochi.
