Hi thanks for the replies:- I was directed by UKPA to a website www.gov.uk/foreign-travel-advice/australia/entry-requirements and it states about 'Passport validity' = your passport should be valid for the proposed duration of your stay. No additional period of validity beyond this is required. If you are transiting another country en route to or from Australia, make sure you check the entry requirements for that country. So its looking like I'm okay! just thought I would pass on this information ! Grannygook
