Australian political leaders have condemned the attack on Mr Trump at a political rally in Pennsylvania, held ahead of the Republican Party's national convention.
Anthony Albanese said there was heightened concern following the shooting and called for peaceful democratic processes in Australia not to be taken for granted.
"It was a shock to the system, we know that increasingly United States politics has become very polarised, and tragically, there is a history, of course, with violence," he told ABC Radio on Monday.
"It's a great thing that in Australia by and large, politicians - including the prime minister - can wander about events and can walk around safely.
"(The respect for democratic processes) is a good thing we have here, and it's important that we don't take it for granted, it's important that democracy be cherished."
US President Joe Biden has ordered the country's Secret Service to review security measures ahead of the Republican convention.
Treasurer Jim Chalmers said there was relief Mr Trump was OK.
"We've seen politics get uglier and more polarised and unfortunately, more violent, and I think a lot of people around the world and around Australia are worried about those developments," he told Nine's Today program on Monday.
"We can't see this extreme polarisation, this extreme violence, be normalised in democracies around the world, we're supposed to settle our differences with votes, not with violence.
"What we saw yesterday was completely abhorrent."
Shadow treasurer Angus Taylor said while America had become politically divided, violence was not the solution.
"The whole point of democracy is we get our chance to have our say at the ballot box and that's true in any great democratic nation," he said.
"We've got to keep coming back to that and calling out completely unacceptable behaviour, clearly, and it's not what we want to ever see here in Australia."
Opposition home affairs spokesman James Paterson said Australia cannot be complacent about threats to elected officials or candidates.
"While it's true we've got very different gun safety regulations ... there are some troubling signs that there are trends towards using violent means, in Australia, to try and intimidate parliamentarians and their staff," he told ABC Radio.
"We cannot allow that to take hold here."
NDIS Minister Bill Shorten said the attempted assassination was "shocking and deplorable".
"In terms of here in Australia, yeah, the rhetoric does have to be dialled down," he told Seven's Sunrise program.
"We can make our point without creating a sense that it's all in and that we're at war with each other, because that isn't the case, and that's not the Australian way. And it's not the democratic way anywhere."
