I witnessed in the early 80's guys [I couldn't call them fisherman] trying to catch 'BIG' GTs off the Urangan Pier at Hervey Bay
. They used telecom rope tied to the wooden rail at one end and a big torpedo swivel to about 2m of clothes line wire that attached to a 12/0 hook at the other
. They used large Puffer fish as live bait and when the GTs smashed the bait it was hook up or most often, GONE!!!. Explosive visual stuff.
