When foreign nationals attempt to enter Australia on unseaworthy boats and burn themselves on uninsulated exhaust pipes who is really to blame. I worked on ships doing maintenance and never saw uninsulated exhaust pipes and if any such things where to be found the ship would be stopped from leaving port until repairs were effected.
The blame for burnt hands on asylum seekers rests with the owners of the boats and the skipper of these boats, no one else.
If you are the master of a boat you are responsible for all activities on your boat no one else. Injuries sustained on uninsulated exhaust pipes are the problem of the master not the country you are about to invade.
