Qatar Airways Privilege Club - advice please. business LHR to MEL

Considering Qatar for the first time. Would welcome some advice.

Are all the 777s from LHR to Doha 180 flat beds? I'm assuming this is the plane to choose rather than the angled beds on other planes, or am I wrong?

Thanks

Yes all 77Ws and 77LRs are full 180 degrees flat beds. The Airbus's arent, but if you get a bulkhead seat you do get more space on the Airbus's.
