Yes John Langley came to Aus in 1903 on Runic...did he divorce Hannah??
He married Carrie Ann Cartledge lived in melb and owned Union Hat Mills with brother Arthur Langley
The manifest for the ship RUNIC to Australia in 1903 shows LANGLEY, John. Aged 42. Hatter.
Married. Contracted to land Sydney
It is possible Hannah was arranged to follow with the children, but became ill and not able to follow. Upon her death, perhaps Ernest took charge to bring the younger children to their father.
It is also possible John returned to England at that time to mark the passing of his wife and then again back to Australia.

ADDINGIn case you do not have it, Arthur LANGLEY aged 38 and married arrived in 1904 per RUNIC with his wife and 2 children. He was a Farrier and contracted for landing in Sydney
