Over the years, Ms Colyer has raised tens of thousands of dollars for the cause, again setting herself a target of $5000 this year.

“I thought I’d stay dry from any rain, but then heard a rat on the move, although it was probably only a mouse,” Ms Colyer said.
Her partner, Access Housing chief executive Garry Ellender, will join her for his third sleepout.
“I think we are the only couple who participate.”
Ms Colyer said no-one gets any sleep on the night, but there are no complaints knowing thousands of people sleep rough every night.

Anglicare WA released a report last month that found one in four West Australians had been touched by homelessness, and one in 10 had experienced it themselves at some point.
The report also showed support for more public housing.
In WA, the leading cause of homelessness is family breakdown and domestic violence, representing 34 per cent of the 10,000 people experiencing homelessness in WA.
St Vincent de Paul Society WA chief executive Mark Fitzpatrick said the issue of female homelessness was linked to a lack of social and affordable housing when women flee violence.
