A man has been charged with two counts of murder after his daughter and wife were found dead in a Queensland home last week moments after he was struck by a car nearby.

Kate Paterson, 38, and her one-year-old daughter, April, were found dead with apparent stab wounds in the family's Bannockburn home on March 12 after the child's father, 38-year-old Blake Seers, was struck by a vehicle just a few hundred metres away.

Officers responding to Seers' injuries went to the home to notify his family, but instead found the mother and daughter dead with "injuries consistent with an edged weapon", Detective Superintendent Chris Ahearn said.

He continues to receive medical treatment in hospital and is due to appear in Brisbane court via video link tomorrow.
