Prime Minister Malcolm Turnbull hopes to one day end the “national shame” of domestic violence, pledging $100 million for women escaping their abusive partners.

Making it clear the issue is a top priority for his government, Mr Turnbull used his first major announcement as prime minister to boost support services.

An emotional Australian of the Year Rosie Batty – whose 11-year-old son Luke was killed by his father – congratulated Mr Turnbull for starting to “walk the walk” with the package that improves legal access for victims.

It also funds practical measures, like 20,000 phones with pre-paid credit so women can discard their mobile – which can be tracked – and cut off perpetrators.
