Pat Cummins has urged Australians to donate blood, as the nation's sporting organisations wrapped their arms around the Jewish community and victims of the Bondi attack.
Preparations for Wednesday's third Ashes Test continued on Monday, albeit with the sadness of Sunday night's terror attack in Sydney hanging over Adelaide Oval.
Both sides had grown aware of the Bondi Beach attack on Sunday night, with 15 people killed when father-and-son terrorists opened fire at a Jewish festival.
Increased security is expected for the Adelaide Test, with South Australia Police Commissioner Grant Stevens confirming specially trained police would be deployed carrying stronger weapons.
England's Test team said they were "deeply saddened by the horrific events", and that they stood by the people of Sydney and the Jewish community.
Nathan Lyon told reporters in Adelaide he was "extremely saddened", adding nothing he could say "would make anyone feel better".
Cummins, who lives with his young family in the nearby suburb of Bronte, said on Instagram he was "absolutely devastated by the horror last night in Bondi".
"My heart goes out to the victims, their families, the people of Bondi and our Jewish community during this time," Cummins wrote.
"If you can, please book an appointment to donate blood."
Usman Khawaja expressed similar sentiments, writing in an Instagram story on Monday morning that he is "praying for the Jewish and Bondi community as a whole".
"No room whatsoever for these hate crimes," he wrote.
The Australia Red Cross Lifeblood has called for donations from across the country to help the wounded, with a desperate need for O-type donors.
The NRL's Sydney Roosters and their AFL counterparts the Sydney Swans headlined the list of Australian sporting clubs to express sympathy and sadness.
Players and staff from both teams are regulars at Bondi Beach.
"We are deeply shocked and shattered," Swans chief executive Matthew Pavlich said in a statement.
"To our Jewish community, we are feeling for you and send our sincere condolences to all in your community. Our thoughts are with the victims and their families at this tragic time."
AFL chair Richard Goyder and chief executive Andrew Dillon released a joint statement, describing it as "a time to come together to grieve, to support one another, and to stand with our Jewish colleagues and friends".
"Every person in our country has the right to celebrate their faith in peace and safety, including our Jewish community," they said.
Former England Test captain Michael Vaughan, who is in Australia commentating on the Ashes, was in Bondi at the time of the attack and sheltered in a restaurant.
"I have never experienced anything like it," Vaughan wrote in his column for UK newspaper The Telegraph.
"We were having a drink in the Royal pub next door, and I was on the phone outside. The bouncer walked over with his hands in a gun sign and told me to get inside.
"To be so close that you can hear it happening is terrifying."
