Calling all Aussies that have driven In the UK

Or anyone that knows driving law in UK

Can someone confirm for me that when wanting to drive in the uk the aussie resident will have to actually have their licence with them in the UK?

And therefore if they have had their licence revoked for say 6 months in Melbourne ,
, for speeding they cannot legally drive in the uk??
I'm therefore also assuming insurance would be invalid for false information having claimed to have a kicence when it was in fact revoked at the time? ?

All factual info great fully received
