Home Affairs Minister Peter Dutton has requested a federal parliamentary committee to look into a proposed law that would enable police to access encrypted messages.

Dutton wants the law to pass before the end of the year and has written to the committee leader, Andrew Hastie to fasttrack the report.

The Minister says he is “gravely concerned that [Australian] agencies cannot rule out the possibility that others may also have been inspired by events in Melbourne to plan and execute attacks" hence his desire for access to encrypted messages.
