NSW mum missing with eight kids

Police hold concerns for a NSW woman missing with her eight children.

They haven't been seen since boarding a train on the state's Central Coast.

Rachel Pawsey and her children, aged between two and 14, were last seen at Wyong Station on Friday.

It's thought the 39-year-old, from Niagara Park, may be heading to Queensland.

Police say some of the children require medicine and it's believed they only have a limited supply with them.
