Lyons was made a Dame Grand Cross of the Order of the British Empire (GBE) in the Coronation Honours of 1937. Joseph Lyons died in 1939, aged 59, the first Australian Prime Minister to die in office, and Dame Enid returned to Tasmania. She bitterly resented Joseph Lyons's successor as leader of the UAP, Robert Menzies, who had, she believed, betrayed her husband by resigning from the Cabinet, shortly before Joseph's death.
