When the temperature drops, the city's crisis accommodation centres are brought to capacity.
Support workers have spoken of their fear that too many will be turned away from the care they need unless something is done to address the problem of 'hidden homelessness'.
"Most people who experience homelessness in Australia experience 'hidden homelessness'," said Heather Manning, Mission Australia Wagga's area manager.
"While they might have a roof over their head, they do not have a place to call home."
In 2016, at the last census there were 200 people deemed to be homeless in Wagga.
Some will find temporary shelter in a friend's home or in one of the city's crisis accommodation houses.
When those options are exhausted, the street becomes the last refuge.
Research compiled by St Vincent de Paul Society reveals one in every eight Australians is currently living in poverty.
Additionally, one in four are suffering loneliness, which Ms Manning said can often exacerbate the problem, especially during the winter months.
The feeling of loneliness increases a person's susceptibility to the cold. When you feel lonely, you're more likely to feel the cold.
"One of the most important things we can do as a community is be kind to people," Ms Manning said.
"Homeless people can often feel excluded from their communities, and there is nothing more isolating than other people ignoring you."
The problem of homelessness in the Riverina is particularly pronounced among young people.
Last year, 700 people made contact with Mission Australia's Eastern Murrumbidgee Youth Services.
But with only five crisis accommodation beds available across the region, the needs far outweigh the available resources.
"One of the most important solutions to homelessness is to increase the number of social or affordable homes available for people to access," Ms Manning said.
"While crisis and transitional accommodation is important, without appropriate and affordable long-term housing, too many people will continue to be pushed into homelessness."
