The May 18 election will be the first time Bhakti Parbhoo has ever voted in an election that isn't rigged.
But after the leaders' debate in Brisbane she's still unsure who to support.
"I have absolutely no idea who to vote for, still," she told AAP on Friday after the debate.
"I believe strongly in a lot of the policies that Labor stands for but I do believe they're going to make us broke."
Ms Parbhoo was one of 16 per cent of the 109-strong audience still undecided on who to vote for after the debate, while 43 per cent picked Labor leader Bill Shorten and 41 per cent picked Prime Minister Scott Morrison.
The immigrant from Zimbabwe said she would find it hard to vote for the Liberal Party due to "hateful" members such as government minister Peter Dutton, as well as the party's ties to Pauline Hanson.
Ms Parbhoo has only ever voted once before, but said her voice in Zimbabwe didn't matter.
"I only voted once because I was too scared to vote. But I did it once because I felt it would make a difference and it didn't," she said.
"The votes were rigged, so this (the election) is very important for me."
Young Australians shouldn't take their vote for granted, she added.
Mr Shorten won over Mick, who voted for the Labor leader over Mr Morrison.
"I think he was just more informed with the issues that matter to me and matter to the Australian public as well," he told AAP.
"He just seemed to win the debate as far as I'm concerned."
But Dirk Bowen-Rotsaeit voted for the prime minister due to his stronger economic arguments.
"I did see one event which Bill Shorten attended in the previous election, and he doesn't seem to have progressed. He was struggling for figures on a few occasions then and he seemed to this time."
