The sister of murdered UK MP Jo Cox has called on Australia to see the attack that left independent MP Helen Haines in a critical condition as a turning point.
Cox was murdered aged 41 in 2016, when she was shot and stabbed multiple times by a far-right extremist.
Since then, former UK MP Ann Widdecombe was killed this year and sitting UK MP Sir David Amess was killed in 2021.
Kim Leadbeater, who is now the MP of the constituency formerly held by her late sister, called on Australia to unite against these kind of attacks.
"Maybe for Australia this is your moment to think about what your politics looks like and how we can bring people together [and] find common ground," Ms Leadbeater told 7.30.
"That was something my sister was brilliant at, and I would imagine it's something Helen [Haines] is good at.
"I am devastated for Helen and for her family, her friends, her colleagues, her staff, that I am probably one of the few people, I suppose, that can understand a little bit of what they're going through."
She echoed calls from politicians, including Prime Minister Anthony Albanese, for a calmer discourse.
The really depressing thing for me is I've been giving a very similar interview for the last 10 years about how we need to look at our political culture in this country, and it would seem in other countries as well," Ms Leadbeater said.
"I find it really frustrating that we're having the same conversation and every time something so horrific happens."
She said while robust political debate was important, she believed more civilised comment was needed.
"Things don't happen in a vacuum and horrendous attacks and incidents like this don't happen in isolation," she said.
"They are part of a wider culture around politics and society [and] we all have a role to play in that."
