Yes, unfair dismissal is really to protect people who are dismissed without warning or for no good reason (i.e. - the boss does not like you).
Anti-discrimination is designed to protect specific groups of people (women, aborigines, immigrant, disabled people) who are subject to systematic discrimination.
i.e. unfair dismissal probably keeps incompetent people in jobs, anti-discrimination actually protects people who probably need assistance...hehe.
