I have done this pass twice, and never even knew it was called Boomerang Pass (as per Fitzroy Falls and Beyond book)!
GR 418227 (OLD GRID REFERENCE) Nerriga.
The pass is fairly easy to find at the top through some natural large openings that sort of zig-zag through the cliffline. Just north of prow in the top cliffs from memory.
It does get very steep as you get down to Ettrema Creek- meaning the part closer to Ettrema Creek is more difficult than the part through the cliff line.
