The Australian Electoral Commission is targeting the homeless in an effort to boost voting among those sleeping rough.
A pilot program being trialled in WA has seen mobile polling booths set up at three Perth community centres.
Homelessness is on the rise nationally with 13,000 people believed to be sleeping rough in Perth alone.
Under the scheme, the homeless can can choose to have their vote count at their last known address, where they grew up, or in the electorate where the shelter is located.
The program was launched after criticism at the last federal election that not enough had been done to engage Australia's homeless community.
Brendon Barlow from the Australian Electoral Commission says the scheme has already proven a success with 57 people casting their vote at St Patrick's Community Support Centre this morning.
"Prior to this we hadn't done anything in this sort of area before so this really is a first for WA in how we engage with the homeless community," he said.
"Certainly we have a problem with making sure they're entitled to vote so we've got a program in place where they can actually enrol with no fixed address and we've tried to make sure that's become widely available and known to people in these sorts of environments."
Karl Smith lost his job six months ago and has been living on the streets and in homeless shelters since then.
Despite having no fixed address, it was important to him to vote.
"It all makes a difference in the end and it's all going to make a difference on the way the future goes so I guess it's quite important that everyone has a say," Mr Smith said.
St Patrick's chief executive Michael Piu says the response from the centre's clients has been wholly positive.
"This is a safe place for them it's non-judgemental, it's probably the one place some of our clients would ever consider exercising their right to vote," he said.
"I've seen cases of clients with mental health [problems] that really find the system confounding and they were helped through the process and they were given voice so yes, it's a wonderful program and a great change for the better."
The AEC expects 120 people to vote at WA community support centres before Saturday.
