Federal member for Indi Helen Haines underwent the amputation of both her legs after 43-year-old Brendan Nugent allegedly deliberately struck her with his four-wheel drive.
She remains in a critical condition in Melbourne's Alfred Hospital.
In the days since, the nation's police forces, Home Affairs department and state leaders have rushed to crack down on security and offer briefings.It comes against a broader backdrop of threats to politicians.
Federal Communications Minister Anika Wells shut her office after an incident on Wednesday.
"Unfortunately, I've been advised we need to close the office temporarily while security improvements are made," Ms Wells said in a statement on Friday.
"Our staff deserve to feel safe at work and this kind of behaviour is unacceptable."
Queensland Police charged a 47-year-old Nundah woman with public nuisance over the incident.
Federal Energy Minister Chris Bowen urged members of the public to leave politicians alone, regardless of which party they belonged to.
"Whether it's 'stone them in the square' or whether it's Warren Mundine, frankly, telling jokes at CPAC about bashing me up, physical violence to me, it's not funny," he told News24."Every Australian in politics is doing a job, plenty of people I disagree with, but they're fine Australians, just going about trying to do their job. No one deserves violence."
Mr Bowen was referring to Question Time comments by Liberal MP Angie Bell suggesting Small Business Minister Anne Aly should be "stoned and shamed in public".
Former Liberal party candidate Warren Mundine joked at the conservative CPAC conference earlier in October that a friend had admonished him not to murder Mr Bowen after bumping into him in Canberra.
A man was also charged in Western Australia this week for allegedly making threats and wielding nunchucks in the electorate office of state Labor MP Hannah Beazley.
In NSW, some parliamentarians who attended a state police-run briefing said they were left with broader concerns about their safety and felt examples given were politicised.
They were told to monitor their surroundings closely and alert NSW Police to their movements.
An app for a beacon to alert police of safety concerns was also encouraged.
A series of images of public protests - including a March for Australia rally, a pro-Palestine march against the Sydney Harbour Bridge and an image of children at a climate protest - were reportedly shown as examples of situations where MPs could be unsafe.
Victorian politicians also received a security briefing. A second briefing for those unable to attend will occur on Friday night.
Victorian Greens Leader Ellen Sandell called on Premier Ben Carroll to put together a memorandum of understanding between all political parties before the state election next month.
"We should all be setting the example and a higher standard when it comes to political discourse and campaigning," she said in a statement.
Federal parliamentarians have also been briefed on keeping themselves and their staff safe.
The Australian Federal Police, NSW Police and Victorian Police have been contacted for comment.
