The government is shaking up the social housing system - to bring in more stringent criteria about who gets a state house and possibly, new tenancy duration limits. It's boosting support for more than 100,000 families by an average of $15 a week - but leaving another 80,000 worse off by an average of $30 a week. The opposition said the changes are "cruel" and will lead to more evictions of public housing tenants, who will be "driven deeper into poverty." Political reporter Lillian Hanly has more.
