UPDATE: Sara Zelenak Identified As Second Australian Killed In London Attacks

Malcolm Turnbull says he has spoken to the families of Zelenak and nurse Kirsty Boden.

Queensland woman Sara Zelenak has been confirmed as the second Australian to have been killed in the London terror attack.

Zelenak's mother Julie Wallace confirmed the news on Wednesday afternoon that her 21-year-old daughter was a fatal victim of the deadly attacks, which also killed South Australian nurse Kirsty Boden and five others.

Earlier Wednesday, Prime Minister Malcolm Turnbull said he had spoken to the families of both Boden and Zelenak after Julie Bishop confirmed two Australians had been killed in London.

Boden's family on Tuesday night confirmed the South Australian nurse was killed while trying to help people fleeing the terror attacks on London Bridge on Sunday.

"Kirsty Boden was a young nurse who went to help victims of the attack and tragically has been killed by these cowardly, vicious terrorists," Turnbull said on 3AW.

"Sara Zelenak is a young Australian 21-year-old who was working in London, an au pair...whose circumstances have been the subject of very grave concern."

Zelenak was reportedly separated from her friends during the attack and her family had not heard from her since, the ABC reported.

In a statement on Wednesday morning, Bishop said that the Government was "deeply saddened" to confirm the death.

"We continue to work with the United Kingdom authorities who have asked that we await official confirmation of the identities of the victims, and for the families to be officially notified, before we release their names."

Boden was named as one of the seven victims of the attacks on Tuesday evening. The 28-year-old nurse has been hailed as a hero and an "outgoing, kind and generous" person by her family in a statement.

"Kirsty was loved and adored by her family, friends and boyfriend. She was the most outgoing, kind and generous person who loved to help people. Helping people was what she loved to do in her job as a nurse and in her daily life," the statement read.

South Australian Premier Jay Weatherill told reporters on Wednesday morning that Boden's death touched the "life of every South Australian".

"Every death is a tragedy but this particular event seems to touch us in a particular way -- a country girl from South Australia dying in an act of global terrorism seems to reach into every single one of our homes."
