Charity groups in northern New South Wales have raised concerns the upcoming Gold Coast Commonwealth Games will strain their resources as persons experiencing homelessness move south as they are crowded out of the city.

St Vincent de Paul Lismore spokeswoman Linda Williams said Games preparations have affected access to some popular rough-sleeping spots.

Queensland housing minister Mick de Brenni said homeless people won’t be “moved on” from the Gold Coast “until such time as they're required to have a ticket.”
