A Brisbane schoolboy allegedly planned an attack involving the coalition leader in the first half of 2024 before being arrested in August, according to News Corp.
AAP has confirmed the 16-year-old was on Thursday committed to stand trial in Brisbane's Supreme Court after being charged with a commonwealth offence of committing acts done "in preparation for, or planning, a terrorist act".
Prime Minister Anthony Albanese said a growing number of threats against parliamentarians had led to strengthened security measures.
"We do live in times that, we've seen around the world but here as well, these threats (are) made," he told reporters in Darwin on Friday.
"There's no place whatsoever in politics for any of this and I have ensured that any time any member of parliament, regardless of who they are, have asked for support, they have received it.
"I've reached out to Peter Dutton this morning."
Mr Dutton's deputy Sussan Ley said the case was concerning.
"We can't let this become the new normal in Australia," she told Seven's Sunrise program on Friday.
Ms Ley noted the revelation added to recent difficult personal news for Mr Dutton, whose father was rushed to hospital after suffering a heart attack, ahead of his election debate with the prime minister on Tuesday.
The news of the alleged terror plot also comes after new polling showed Mr Dutton's standing with voters has slipped again.
The YouGov poll released on Friday found Mr Albanese has increased his lead as preferred prime minister by four points to 48 per cent, against Mr Dutton's 37 per cent.
As politicians travel the country in the lead-up to the May 3 national election, Labor minister Jason Clare hoped the leaders could continue interacting with the public as usual.
"In Australia, in a democracy, you make your arguments with words, not weapons," he told Sunrise.
"If people want to come up to us and have a chat, they can.
"If they don't like us, then they might mumble something under their breath or cross the road - you never want to see the sorts of threats of physical violence happen, like we've seen overseas."
Mr Dutton was in Western Australia on Friday to spruik a coalition promise to abolish penalties for fuel-guzzling cars, if the coalition wins government.
The federal government's vehicle efficiency scheme is currently designed to encourage the uptake of electric and more fuel-efficient cars.
It sets emission targets for vehicles and imposes penalties on automakers whose fleets fall short of those limits, or if they fail to trade credits with other car brands.
