Following the Second World War, the Sexual Revolution during the 1960s led a change in societal attitudes towards matters of sex, birth control, and motherhood including abortion. These also gave rise to the emergence of Second-wave feminism and the Women's liberation movement during the 1960s and 1970s. Between 1965 and 1970, the number of abortions performed in public hospitals jumped from 70 in 1965 to more than 300 by 1970. Public debate increased following the legalisation of abortion in Britain in 1967, and court decisions in Australia in 1967 and 1970 legalising abortion. The legalisation of abortion in Australia enabled New Zealand women who could afford to travel there to have abortions in Australia.
