I'm from the states but I know first hand down here if you don't have a hook and all you have is a weight, a game officer is NOT going to ticket you. How could it be considered fishing? It's called casting and I bet your buddy would get bored of casting after 30-60 minutes anyway. There have been a few protests on the lower Skagit River during the closed season for Wild Steelhead where a bunch of guys did just that, casting weights without any hooks. Not one person was charged with a fishing violation. However for the very little cost of a one day license who knows, maybe he could learn to cast and also get lucky and catch a fish! If he doesn't buy a license and goes casting and gets caught, as long as he doesn't look like some lying, low life white trash I'm sure the game officer will be logical about it. On the other hand, if he looks shifty or questionable to start with I'd buy the license as there will be a better chance the officer might think he's full of poo and trying to get away with "fishing" without a license.
