What part did draft resisters play in the Australian anti-war movement?

The introduction of conscription in 1967 was highly controversial. 20-year-old men were selected based on a ballot where birth dates were drawn from a barrel. Immediately some men refused the call-up. Over the next few years men such as teacher Bill White, journalist Simon Townsend and postman John Zarb provided high profile resistance to the National Service Act. These individuals and others helped to build more widespread anti-war activities such as demonstrations and production of anti-war leaflets. The impact on their private lives, however, was substantial.
