I've sent off for a quote too! 20ft container from Buckinghamshire to Far North Coast NSW. Will let you know what comes in.
I'm so stressed about what to take and what not too. If I can keep costs down with self shipping then I won't need to worry and take it all! I am not taking beds or large lounges etc. So think i should have plenty of space in 20ft.
The idea of a MOVECube scares me that it won't be enough but by the time you do two of those isn't it better to go for a 20ft container? I think I need to go back and look at dimensions of each
