Housing affordability crisis bonds Sydney community across cultures and religions

A mother and baby at a forum.

Single mum Nadine Carrick was among 600 people from across Sydney last night who came together to make impassioned pleas for the housing affordability crisis to be tackled.

Ms Carrick, a full-time student studying town planning, said she was paying 70 per cent of her income towards rent.

"We all have a right to this city and to be part of the community and we demand action, for the Government to take action, because what else are they there for?" she said.

Ms Carrick said the cost of living in Sydney outstripped her income by about $200 per week.

"My car, I can't even really afford to run my car at the moment," she said.

"The priority is a roof over our head, food and some petrol for the car to get around."

The forum saw a diverse group converge on St Mary's Cathedral Hall and take a stand against the price of housing in Sydney.

The Catholic Archbishop of Sydney attended and mingled with other faith groups, single mums, business leaders, trade unionists and former homeless drug addicts.
