This may have been covered before? For many years I've never been asked to confirm my address when doing my 90 days. I've noticed that the latest reminder slip is green, normally white, and says 'Notify your address on ------'. Will I have to do this or just hand my passport over as usual?

That means doing your 90 day report. It often referred to as doing a 90 day address report.

You don't need to prove your address when you do the report.

Thankyou for your rapid response.

The purpose of 90 day reports is to notify/update your address.
