Luke i have been sending eggs through aust post for many years now. Unfortunately they do not offer a fragile service nor will they allow you to insure eggs so it is pot luck that they make it ok. I have had most of mine make it well but one lot i sent to S.A was totally trashed by Aust post.
We should get something together to help make a fragile section to Aust post (doubt it will work though.lol.).
Wow so you post all over Aus?
