Some organisations that might be able to help (no promises though!)
Australian Working Women's Services. Working women's services in each Australian state are highly recommended if you need help. Each state has a freecall service for information and referral on all employment matters.
Human Rights Commission.This site lists each of the Human rights and Anti Discrimination Commissions by State and Territory. Ganging up against someone can be in relation to a characteristic that distinguishes a person as different to the in group. Difference because of gender, race, age, marital status, social class, accent, ill health or impairment, sexual orientation, religious or political views, puts you at high risk. Complaints must be lodged within 12 months.
Australian Council of Trade Unions
The ACTU lists every Union in Australia by State where assistance may be obtained if you are already a union member.
