When I shipped all my stuff back from Germany - Perth, I found all the removal companies ridiculously expensive, so I looked at sea/surface mail (I wasn't paying, but the less it cost the more I could bring across from brissie). Only problem is it doesn't exist in Germany (especially souther Germany). Cheapest was off-peak air mail (10-15 days) - about $150 per 20kg. I looked at Aussie post sea mail for the reverse of the same leg (for comparison), and it was $270 or thereabouts!!!
I stopped complaining about the cost after that...
