Oliver Peterson: Australian correspondent on the 554 people being arrested in domestic violence crackdown - Heather du Plessis-Allan Drive

Over in Australia, NSW authorities have arrested at least 500 people for domestic and family violence offences.

A four-day operation was carried out from Wednesday to Saturday - where 554 people were arrested and 1,070 charges were laid.

Australian correspondent Oliver Peterson wonders why it's taken so long to carry out these arrests, given several had outstanding warrants.
