I'm just interested in the fact that there's a witness needed to sign a declaration. I suppose it's inevitable that Defence Force personnel, even on deployment, will have the opportunity to have a witness available to sign and verify the declaration that they have made under regulation 52 of the Electoral Regulations 1996. On Navy ships, this might be in what's called the ship's office where a new sailor would be encouraged to go and ask for a "thick regulator", which sounds like a bit of engineering kit but, actually, it's a rude way of describing one of the naval policemen or police persons. A regulator being, sort of, the shorthand for that, in the way of being asked for a can of striped paint, or a left-handed hammer, and so on.
