After Andrew Wilkinson and the deaths of their two children, Charlotte took up with one Albert Charles Wollschlager. In 1946 she was charged with arson in Longreach and was freed with a 5 pound bond. In 1952 she is mentioned in the reports of an assault on Wollschlager by Henry Ewan/Yuen. The articles can be found in Trove. There is a death for a Harriet Charlotte Wollschlager, Dec 1969 in the North Rockhampton Cemetery records which might be her, although I don't know that she ever married Wollschlager. He died in 1963.
