A north Queensland mother charged with manslaughter over the drownings of her young sons has been refused bail.
The bodies of Barak Austral, 5, and Jhulio Sariago, 3, were found in Townsville's Ross River after wandering away from their home on February 25.
Their mother Leanne Eatts was charged with manslaughter and serious drug offences and remanded to appear on May 17 during an appearance at Townsville Magistrates Court on Saturday morning.
The magistrate refused bail and said the safety of Eatts and the community could be at risk if she was released, the ABC reported.
On Friday, Detective Dave Miles said Ms Eatts was solely responsible for her sons' preventable deaths on the day the boys wandered off alone and drowned.
"There is no way these boys should have been left the way they were, or ... allowed to go down to the river," he said.
"Certainly, their deaths under appropriate parental supervision would have been averted."
Det Miles said it was not an isolated event but a "systemic behaviour" by their mother and the lack of supervision.
Police are also investigating if drugs or alcohol were factors in the boys' deaths.
