I've tried these:
Australia Post - no, because device (golf launch monitor) has a lithium battery in it.
Sendle - no, because $2000 max value and this is $3000. Also no insurance option. They're ok with the battery.
Fedex - 3-4x the price of Australia Post and Sendle.
Pack n Send - have to travel 30 minutes to nearest depot as can't do items with lithium battery via their self service. Have to email for quote too.
Any other services typically seen on OzBargain to handle Australia -> US that I can investigate?
find someone going to the US and a$k them to take it.
