Ockoman,
How fortuitous to come across your request.
I got my first mac last Saturday arvo near shallow tempest.
We were in 30m of water and it took a good sized squid tentacle.
It took the top hook of a paternoster rig, which surprised me because it was about 2m off the bottom.
It measured 87cm and a guess of the weight says maybe 8kg - it was too big to just cut up for bait, and I believe they're not great on the chew, so it went back to fight another day.
Hope others will add theirs, I'll be interested to see what's been caught.
Cheers,
Steve
