The full story: due to legal requirements, the US and initially it seemed Oz too, needed to have retailers include with the item the safety cap; that means opening the box and attaching the cap to the barrel, with glue or other means. Retailers decided to do this to be covered and the ensure customers would receive the item in case of inspection. After review and feedback from Australian customers, however, HLJ has decided not to open packaging and not to attach the cap! This is still the case, though, for US customers. See a screenshot of the discussion below.
