We need an inquiry into the 3G issue to get to the bottom of what the government knew about the 4G phones that won't connect to the 000 service when the 3G network shuts down. On 17 March, the minister said she became aware of the looming crisis regarding 4G phones only 10 days earlier. This is very hard to believe. We know that key industry associations flagged this issue with the minister's office and indeed the department last November. We need to investigate the government's actions—or, more to the point, their lack of action—on the whole 3G shutdown.
