Think i can give some good advice for this as i am going in two days
Usually people go traveling straight after Uni but it is possible to do it later like i have.
I finished Uni, got a job in London and worked there for 3 years. Worked my ass off, got plenty of experience and saved everything i could even whilst renting a flat in Essex/London.
I haven't saved as much as i could by living at home and its taken me a good 3/4 years to get the money, but i have enough to do what i want to do and with the experience i have i hope to get a job with my company in there Sydney office once i get to Oz.
In total ill have just over 7k spending money and i'm going alone.
Any questions give me a shout.
