Point 1... Nadi is actually located on the Western cost of Fiji, not the Eastern!
Point 2... Doesn't it make perfectly normal sense that when a mix of high & low MSA's are designated, as is the case here, that there is a pretty good chance that the 10NM MSA will be higher than some of the 25NM MSA's as it comprises a 10NM sector in all directions as is the case here.
Point 3... Arrivals into Nadi are pretty straight fwd - you either get cleared to the MI NDB from the south and join straight onto the ILS, or from the North get cleared to NN VOR and join the ILS via the R204 reversal.
Touch down. Get beer in hand. Score a hot sweedish back packer down at Nadi Bay Hotel then drag it back to the hotel.
Done. Game over. Enough said!
Waaaaay toooo much effort gone into the original post!
Speaking of back packers.....
