Specifically it could aim to:
1. Commemorate the individuals and movements that have campaigned against war throughout Australian history.
2. Remember ALL the victims of the imperial wars in which Australia has fought - civilians and military on all sides.
3. Promote an antiwar culture as a counterpoint to the jingoism that attends Anzac Day and the Anzac mythology.
A suitable form of commemoration might be a candlelit sunset vigil as a counterpoint to the Anzac Day Dawn Service - a reminder that for war's victims the day is not beginning - it has ended.
This kind of commemoration could also start slowly and grow - it would be good to have something like this established by the time of the 1914 WWI anniversary.
