Fork in the road! Which way to go?

[Flinkman47]

Hey all,
Off the bat I would like to say that I hate posts that ask you to make life decisions for someone.
What I'm asking is: 'is it possible?'

Life in the Uk has taken a bit of a down-turn in the past 6-months, separated from wife(not actually that bad :S), family death and last friday, the cherry on the cake, was made redundant.

I'm now sitting thinking about heading off! I've been seriously thinking about emigrating to Oz for a long time, and i'm starting to think that now might be that time.

The problem I have is, how to get there. The choices I have are take a big bag of money and fly over. Or take a smaller bag of money and bike it there!
Again I have always wanted to tour the world after getting up on two wheels. I'm currently 25 and see it as two choices, I can do it now, turns out to be the best thing I've ever done, or fly over wait till I'm 40 to save up enough money and do it then.

The question I have for you is: Is it possible to bike through EU, Asia and on to oz. I have plenty of time to do the trip, thats not the problem.After I have bought out the bike I want to take(currently on HP). I will have a budget left of £15000($21000). From what I've read, EU would be the most expensive part of the trip, where as Asia would be very cheap and could travel around there for months. I have a friend that lives in Bhukket(Thailand) who told me I could be travelling around for less that £10($15) a day.

Am I being realistic? Can this be done, with some change left over to setup in Oz? Any thoughts or comments welcome!
