Hundreds of people have gathered wearing red caps and draped in Australian flags for a vigil honouring assassinated right-wing activist Charlie Kirk.
The pro-Donald Trump US influencer was fatally shot on Wednesday, US time, while speaking at a university event in Utah, prompting an outpouring of grief from some political leaders and broad condemnation of the violence.
The Australian branch of Turning Point, the conservative group that Mr Kirk grew with his prolific online presence, organised the assembly in Sydney's city centre.
A diverse, overtly Christian crowd attended, with many carrying placards preaching biblical messages while others wore red Make America Great Again caps.
The group's Australian head, Joel Jammal, expressed his patriotism for Australia and called on the crowd to become politically engaged.
"We cannot live in fear ... Australia is worth fighting for," he told the faithful.
"We need to have more kids. We need to get reconnected in church. We need to get politically involved - that's what Charlie was trying to say."
Mr Kirk co-founded Turning Point USA, a conservative advocacy group which was active on university campuses and often found viral fame on social media.
Among his avid viewers were Michelle Graham, who wanted to show her support.
"It all part of the healing process ... it was just so sudden," the 48-year-old told AAP.
"This is not about any political statements or whatnot. It's just being human - and that's what he would have wanted as well."
Mr Kirk had previously praised Melbourne protesters for shutting down a council meeting over a drag story time event for children.
He also railed against Australia's COVID lockdowns, blaming law enforcement for heavy-handed tactics.
Popular Australian online content creator Anthony Khallouf, who rose to prominence for organising anti-lockdown protests, paid tribute to Mr Kirk.
"He's almost like an inspiration for people like myself ... getting involved in the political discourse," the 33-year-old said.
Mr Khallouf lambasted Australian politicians for what he argued was the demonisation of conservative movements.
"The classification of terms they put on us, calling us neo-Nazis, far-right extremists or ... even domestic terrorists all of that is going to just push us to a point where we're going to have this resentment," he said.
Prime Minister Anthony Albanese described the 31-year-old's killing as "horrific".
"I think the world is shocked by such an event, and my heart goes out to Mr Kirk's family."
School-aged children have accessed unedited footage showing the moment of Mr Kirk's violent death, according to reports received by Australia's online safety watchdog.
At least one platform voluntarily removed instances of the video after the eSafety Commission informed the company of the material.
Those who see the video are urged not to share it further and to instead report it to the platform.
Notable Australians including NRL player Jarome Luai and former prime minister Tony Abbott are among those paying tribute to Mr Kirk.
