There've been four days of protests in Melbourne - leading to hundreds of arrests - they've been protesting against the lockdown and demanding a vaccine mandate for the construction industry be lifted.

Things were a bit quieter yesterday - but its a public holiday there today and things have flared up. Rebekah Holt is a New Zealand journalist based in Melbourne.
