Do I need a visa or stamp to enter UK from the Republic of Ireland? I have a 90-day tourist visa stamped in my passport on arrival.
If I get the bus from Dublin to Belfast, and then a flight from Belfast to London, do I need anything in advance?
I read that Australians don't need anything ahead of time for a standard 90-day tourist entry. Is that right?
I also head that there is a 6-month visa for Australians. Does that exist? How do you get it?
The UK and ROI form the "common travel area".
If you enter the UK from outside the common travel area and the landing interview deems you are a legitimate visitor you normally get 6 months "leave to enter". No visa is required.
If you enter via the ROI things get more complicated. Your status depends on your previous UK immigration history and how you entered Ireland. The answer to your other question has a flowchart which helps you figure out what your status will be.
Also based on your other question be aware that coming back as a visitor soon after you left on a youth mobility visa will make the boarder guard more suspicious. You may have an uphill struggle trying to convince the border gaurd that you are a genunine visitor who intends to leave on time and does not intend to work.
