A trolling rod rated at 12 to 15kg, matched with a multiplier with 30lb main line and a 60 to 70lb leader will be fine. With regards to the trace, it depends on what you are targeting. If you going for something with teeth like these big crocodile couta hanging around lately, then a couta trace will need to be used. Hook the single hook through the upper lip so that the livebait can keep its mouth open and not die and hook each treble to each side of the livebait. If targeting tuna or dorado, then use fluorocarbon or monofilament with a circle hook rather. I'm not that clued up on targeting tuna or dorado using livebait though, but I believe 0.80mm fluorocarbon/monofilament and a 6/0 to 8/0 circle hook will work. Hook the livebait through the upper lip or the back, taking care not to go through the spine
I like to tie a balloon on the line about 4 to 5m from the livebait so that it can stay at a certain depth and not swim down into the reef. You can vary the depth of the livebait as you wish
You can use a trap stick while at anchor or drifting
Be prepared to catch your fair share of sharks on your trap stick tho
Hope this helps a bit
