We went with an agent in Swindon I believe, Ian Harrop, most helpful!! On top of the charges of the visa application costs we paid an extra £1500 to the agent, in total, about £3,800, that is with the IELTS (English language certification).
I have just imported my 1978 Toyota Hiace from the uk to Melbourne, lots of paperwork, lots of money, lots of swearing etc. Loads to take in. If you get your visa, drop me line, I will be more than happy to help with what happens at this end.
I work with a guy who emigrated from Birmingham, he submitted his papers in Spetember and was here in January. Good luck!
The only Port Vale fan in Melbourne!
