There appears to be no option given from the suppliers, as they always assume air freight?
It is up to the seller to specify the shipping method.
If batteries are being sent within Australia you just put a Road Only sticker on the parcel and do not sign the Aviation Declaration.
There is not much you can do about anything coming from overseas but hope the seller follows the rules and sends by sea freight.
