Resources were also allocated towards a program for migrants. In August 1973, an Immigration (Education) Act was introduced to provide (as an emergency measure under the child migrant education program) supplementary class-room accommodation in schools with special programs for migrant children. In 1973-74, the number of teachers for special migrant classes increased from 1,000 to 1,500 and the number of children receiving instruction went up from 40,000 to 60,000. Migrant education centres were established in Brisbane, Perth, Adelaide, Melbourne, and Sydney, while a home tutoring scheme was established, designed to instruct migrant women in the English language. In migrant communities in all the states, 48 multilingual welfare officers were employed to overcome the social isolation of underprivileged groups. Portable benefit rights were also introduced, with respect to age, invalid, wives’ and widows’ pensions. Whereas under previous arrangements a pensioner had to live in Australia for 20 years after reaching the age of 16 and only had portability rights in Malta, Turkey, Greece, and Italy, the new provisions allowed a person drawing a pension to take up that benefit anywhere in the world after 10 years of Australian residence in the case of an age pension and after 5 years for most invalid pensions, while no period of residence was required for widows permanently resident in Australia when their husbands died.
