United Kingdom entry changes from 25 February 2026: If you’re an Australian citizen, plus have British or Irish citizenship (dual national), the UK Government has advised you must travel to the UK using either a valid UK passport or Irish passport or any other valid passport with a certificate of entitlement. You will not be able to travel without one of these documents. These dual citizens will be unable to obtain an ETA or visa to enter the UK.
