In March 1973, the service pension was extended to war widows, and in September that year the means test on service pensions was abolished for recipients over the age of 74. In May 1975 the means test was abolished for the age group 70–74 years. Free artificial limbs were also made available through the repatriation artificial limb and appliance centre to all amputees, while free medical and hospital treatment was introduced for veterans of both the Great War and the Boer War and for ex-prisoners of war. The Mental Health and Related Community Services Act of 1973 made grants available to the states for the provision of community-oriented services for drug, alcohol, and mental problems. In 1973, the age limit of 21 years was removed for the payment of additional pension for full-time students and for the payment of guardian's allowance or mother's allowance, and provision was made for payment of additional benefit for a child to continue after their 16th birthday and without limitation on age if the child was a dependent full-time student.
