Im leaving to go to australia for a year in a few days, and ive rather stupidly gone out and bought a huge backpack (80 plus 10 litres)without looking on here, as ive now seen that most people get a much smaller one. I was thinking i will need loads of stuff as im going for a year. Just tried packing it and cant get everything in, and can barely lift it !! Am I taking too much?? I was working on the priciple of the amount i would take on a 2 week holiday plus about an extra weeks worth, after all I will be there for a year, but this is obviously too much. What should I do??? Have considered trying to fit it all in a suitcase instead, as I dont really have time to change backpacks. The majority of my luggage is clothes and shoes, is this wrong?? And would it be wrong to take a suitcase? Help!
