Former Australian of the Year Fiona Stanley questioned the axing of funding for 70 Aboriginal-controlled early childhood intervention services at the same time a royal commission was being held into the Northern Territory's youth detention system.
"Now why am I worried about that? Pathways into suicide start in early childhood," she said.

Prime Minister Malcolm Turnbull has asked Health Minister Sussan Ley to host a summit on the issue in the Kimberley in northern Western Australia and a coronial inquest into the issue has been planned.
Ms Ley's office confirmed a roundtable discussion would be held in Broome in coming weeks about its plan for a suicide prevention trial site in the Kimberley.
"The government is serious about a call to action on suicide, which is why as part of our commitment to improve mental health and reduce suicide rates," minister Ley's spokeswoman said.
