I have won a trip to Efate, Vanuatu, leaving NZ on 15th Aug. 
Has anyone done any land based popper fishing, or is it best to go out on a charter boat.
If so which boat is the best?
After 7 night on the main island we are off to Tanna Island, also any ideas about fishing there would be welcome.

Mate I'm too jealous for words. I've not gone land based in Vanuatu but just come back from the Cooks and learned a couple of things there that will prob hold true out there.
Fishing is off the reef at the edge of the lagoons. I'd take the heaviest poppers you can get and the longest, strongest rod. I brought an 8 ft T curve and it was too short to allow me to cast as far as I needed. Drove me nuts!
Look for the areas where the lagoon drains through the reef and fish around them.
The GTs are apparently beyond the breaking waves so you need to be able to cast a good distance.
Another technique I saw used there a lot was instead of poppers a large clear float that you hlaf fill with water fished about 1m above a little skirt (thyink skippie lure) with about a 2-3/0. The float allows you to cast a long way with essentially an unweighted lure then retrieve it on the surface. Locals swore by it.
When I go back to the Cooks I'll take at least a 12ft rod for the land based...
And take really tough shoes for walking in the water and coral. It's sharp as. And if you cut yourself on it - make sure you clean it really well with antiseptic!
And if you get a chance to meet local fishermen try to get out with them. They catch more fish than the charter boats!
Don't know if this helps at all mate but that's my 2c worth.
Have a GREAT trip, definitely do a charter too if you can.
Cheers

Booties be sweet. Open toe are the go thou. Heaps of opportunities around Port Villa. Not much swell around the coast, lots of visual outcrops around and casting from beaches and reef is so good around there, so don't need to worry about barrier reefs. She is an all together ball game to the coral barrier reefs of the Maaori triangle pacific islands. In fact Casting for GT's around the main island is custom made for it up there. You'll have a blast - no doubt. You really need a reel that can handle the GT's as they are super hard fighters. Plastic coated lockweld wire and fluoro windon traces are is the go as everything has teeth and coral is very unforgiving. Well done mate, any room in the suitcase?
