Shocking news from London, another dark night for the UK. Australian hearts go out to our oldest friends. Stay strong.— Bill Shorten (@billshortenmp) June 3, 2017
Shorten told the ABC Australians need to stick together to act with confidence and vigilance.
"It is at moments like this we throw politics out the window and are united by a determination to keep Australians safe. United by our determination not to let terror run our lives," he said.
"We are united in our response to oppose terrorism."
Shadow Foreign Affairs Minister and Leader of the Opposition in the Senate, Penny Wong, agreed with the Opposition Leader's comments, saying the international community must remain unified.
"Our response to this should be vigilance, but also remaining united," she said.
"What the terrorists want, possibly more than anything, is to ensure we are divided and to drive a wedge into our inclusive community."
UK police have confirmed the death of at least seven victims and three suspects, while more than 48 others have been transported to hospitals across the city.
