In national news, residents of an apartment in Sydney were forced to leave their homes after cracks on the buildings left residents homeless.

The NSW government says it will hold everybody accountable once the cause is identified but until then residents will not be able to return home to collect personal items.

Builders association director Brian Seidler told SBS News the problem is still being investigated and this is the second time cracks in buildings occurred after the Opal tower apartment complex in December.
