Australians cast their votes with country's Prime Minister set to be elected on Saturday

The campaign trail came to an end at the place where he's probably best known.

Scott Morrison cast his own vote in the electorate where his political career began. 

His opposition down the road in Sydney too. 

Labor's Anthony Albanese hasn't lost an opinion poll the entire campaign. But Morrison is now close on his heels. 

These could be Morrison's final hours as Australia's Prime Minister, but he pulled off a miracle win last election and could do the same tonight.

"We're really hoping for some change in Australia," one voter said.

"It's just so exciting, don't know anything about the parties and have to make an informed decision," another person said.

"So you're undecided right now?" Newshub asked. 

"Yes, very much so," the person replied.

More than 17 million Australians will cast their vote on Saturday, in a country where it's illegal not to. 

But for the first time in Australia's history, there's been a record number of early voters. More than half of all eligible Australians had made up their mind before today.

But those who hadn't walked away with Australia's famous democracy sausage - one free to every voter.

"Very important, very important," one person said. 

Perhaps not as important as the outcome of this once-in-every-three-year poll.
