Australian law on Human Rights is very weak as you are finding out. Look at the policy reasons for why the Charter was produced, read about the committee chaired by George Williams setup to implement a charter in Victoria in 2005 (I think).
The Law in Australia has a fragmented approach to human rights. A few examples exist, one being an anti-discrimination act, another the privacy act. Remember to consider both Cth and Vic legislation.
The largest threat to our life and liberty is arguably the State. If this is true, what is the best way of protecting individual's rights against the largest threat they face?
Think about what remedies are available to people who may be imprisoned by a company. Would the State step in to protect people's rights in this situation? If yes, why would we need additional protections?
If a State agency tramples your rights who can you go to?? Complaints against police get handled by police. Does this seem fair? Look up Corinna Horvath as an example of what happens when state powers are abused.
Enough hints here to do say, 2,000 words.
