Four Australians are believed to have been caught up in Saturday night’s London terror attack.

Prime minister Malcolm Turnbull confirmed on Monday afternoon.

While two of those involved were revealed over the weekend, he said there are “very real concerns” for another two.

“At this stage we’re not able to say anything more,” he said.

“We have been in touch with their families, in close touch with their families as we seek to find confirmation of the circumstances.”

This morning Australian foreign minister Julie Bishop confirmed reveal three Australians were involved.

The two additions people are alongside Brisbane woman Candice Hedge, who was in London on a working holiday, and a Darwin man named Andrew Morrison who was stab wound to his neck.

Hedge is recovering in hospital while the other injured Australian, Andrew Morrison, is on his way home.

Over the weekend, Turnbull said: “Our officials will continue to provide every assistance they can to Australians affected by this shocking attack and to their families.

“We have spoken with our Counter Terrorism Coordinator and to our High Commissioner in London Alexander Downer, who is liaising closely with the British authorities.

“We have also spoken to the Director General of Security, the Acting Commissioner of the Australian Federal Police, who’s assured me the AFP is liaising closely with its state counterparts who are stepping up security arrangements for public events in the light of this attack and those that have preceded it, including the shocking attack in Manchester.”

Prime minister Turnbull said up to 130,000 Australians live in the UK.

“We are aware of many Australians who were in the vicinity of the attack,” he said.

Foreign minister Julie Bishop said any Australian who has family and friends in London and has been unable to contact them should call the consular hotline on 1300 555 135.
