Seriously the shipping of LiIon and LiPo batteries has to be one of the biggest threats to aviation in Australia.
How many used phones/computers/iPods/GoPros and spare/replacement batteries are being sent on almost every flight?
I've always wondered how someone who isn't dangerous goods qualified can sign a dangerous goods declaration on a satchel.
As mentioned previously, youtube LiPo explosions if in doubt.
FFS there are ebay AU listings with LITHIUM and EXPRESS POST in the title.....
