You have the wrong end of the stick, my friend. I'm not making a common mistake re descent on a circling approach because I didn't adovcate remaining at MDA until established on final, I quoted some one who did advocate it - Centaurus.
The point of my post, was to point out that if one stayed at the MDA of 1400' on final, say 3nm, at a place like Cairns, one couldn't complete a stabilised approach.
IMHO, short of practice for proficiency, I can't see the point of a DME arrival followed by circling in a jet or high performance turbo-prop, IF a RWY approach is available. In most cases a RWY approach will have a more favourable MDA, and a RWY approach greatly lessens the chance of barreling into the ground because one got distracted at the wrong time whilst performing the circling manoeuvre and ended up with an unrecoverable sink rate, or similar. I'm not saying they shouldn't be flown if necessary, just, why fly it in bad wx if there's a better approach available?
