In 1943 the same counties met in the All-Ireland final for the third year in-a-row. Once again Mills ended up claiming an All-Ireland medal, her goal from fifty yards range being described as the highlight of the match. The following year, 1944, brought a third All-Ireland medal. In 1945 and 1946 a dispute in the camogie association kept Dublin out of the All-Ireland championship in spite of being Leinster champions in both years. In 1948 Dublin were back on form and Mills captured a fourth All-Ireland medal. She took no part in the 1949 championship, however, the 1950s would bring much success to Mills.
