It amazes me that I am a pom living more of the time in the UK than in Australia but I was aware of the change in the policy for sending lithium batteries as soon as it came out, I also knew that you cannor send anything with a lithium battery overseas using Aus Post. How is it that so many 'locals' manage to completely miss these policy changes?

You are not meant to send them in pre paid satchels with the declaration unsigned, you need to send them regular parcel with road only stickers on them.
