I'm no expert either, but the lure is made of lead, weighs 410 grams, and was found on the side of a wall next to Northern Arch. Kev found a second lure of the same type in the same place. My fishing friend tells me they are kingfish jigs. There's absolutely no chance they drifted there, because last time I checked lead doesn't drift that well. I'm pretty confident I know how they got there.
yeah, is a kingi jig- a 'long' jig. It's pretty unusual to jig as shallow as the arch is but if they were noddies they might give it a crack. There's an outside chance a king was hooked and lost elsewhere and has traveled to the arch and dislodged it on the wall: they do a lot of that sort of thing. Somethin fishy, is your avatar pic a Thalasoma?
Saw something similar at Berghans point in january. I think maybe a moon wrasse except it was quite deep (over 20m) which is not typical habitat for them? and being deeper, the colours were all washed out. But it had the lunate, fluoro yellow tail
