'Very Real Concerns' For 2 More Australians In London Terror Attacks

The PM said Australia 'will never give in to terrorism'.

Prime Minister Malcolm Turnbull has expressed "very real concerns" about two more Australians affected by the London terror attacks.

The twin attacks which occurred on London Bridge and Borough Market left seven people dead and 48 injured, including now four Australians.

A Queensland woman, Candice Hedge, is recovering from a stabbing injuring in hospital, while another Australian, Andrew Morrison, is travelling back to Australia after a minor injury.

Turnbull spoke of another two Australians who have been affected by the attacks but cannot reveal more information at this time.

He said they are in touch with the families and are in the process of finding out more information on their condition.

The Prime Minister described the terror acts as "cowardly" and as a "blasphemous corruption of millions of Muslims around the world".

Foreign Minister Julie Bishop echoed the same sentiments, rejecting One Nation leader Pauline Hanson's renewed calls for a Muslim immigration ban.

The Queensland Senator posted a politically opportunistic parody of the London Police's "RUN. TELL. HIDE" message on social media shortly after news of the attacks broke Sunday.

Bishop described terrorism as "brutal" and not respecting "any religion or faith or ethnic background".

"The terrorist threat is so indiscriminate. We've seen terrorists kill Muslims in massive numbers," she told Sky News.

British Prime Minister Theresa May has announced stricter counter-terrorism legislation on Sunday, which will result in extended jail time for less serious offences and closer scrutiny of online radicalism.

"It is time to say enough is enough. Everybody needs to go about their lives as they normally would," May said on the steps of No.10 Downing Street.

In his statement, Turnbull referenced the stricter security and domestic laws his Government has brought in since his ascension to the Prime Ministership.

The newer security laws have resulted in the Australian military targeting and killing terrorists in the Middle East in a "combatant role".

Domestically, terrorists can have an extended jail sentence even after they have served their pre-determined time if "they are found to remain a threat to society".

The Prime Minister was recently in Singapore where he delivered a controversial address on Chinese relations at the Shangri-La Dialogue.

There, he spoke to the delegates about the importance of alliances when it comes to overcoming the increased threat of terrorism.

"Intelligence sharing is absolutely critical," Turnbull said on Monday.

"We are in resolute solidarity with the people of the United Kingdom and our friends and allies around the world," he said.

"We will not buckle or bend or be cowered or intimidated by terrorism."
