Any one have a clew if its worth an Aussie trying for a 12 month non Immigrant visa from the Thai Embassy in London, or will I only get it at home in OZ?

You can get a visa from any thai embassy or consulate.

If i were you i would go to the Thai Consulate in Hull. Far more easy and no hassle.

No chance in London, but you can get from Hull for reason of visiting freinds. You can apply by post and get your passport back within a week. Or go in person. http://www.thaiconsul.co.uk/

Do not even try London, they will only offer you a single.

Not true. Very few Embassies or Consulates around the world will issue a Multi Entry Non O Visa for visiting freinds.

Apparently, if you have a UK address (even a hotel, I suppose) Hull can do it in 3 days.
