For about 50 years in every movement in Melbourne intended to better the conditions of the mass of the people, Mauger was to be found working incessantly and showing much organizing ability. In 1934 Mauger wrote a brochure on "The Rise and Progress of the Metropolitan Fire Brigade, Victoria, Australia", on page 29 some verses relating to the success of the staff fund illustrate his philosophy of life. Basically it was that if anything is brought forward for the good of humanity, difficulties will vanish if the problem is tackled with sufficient courage. Mauger died in Elsternwick, Victoria and is buried in the Melbourne General Cemetery. At his funeral, he was given a fire guard honour. Mauger was survived by his wife, two sons and four daughters.
