It's easy for us (and the ATSB) to arm-chair quarter-back these things, but it does appear he was a little reluctant to go around..
You might want to have another read of the report if your only conclusion was the pilot was reluctant to go-around. The fact that the ATSB has issued two recommendations and does not accept EAL's response to it is an indication of their elevated concern that there will be a fatal accident at LHI. The decision to not go-around was the safer option in a situation where the safety margins had already been reduced to a point that it had become a game of Russian Roulette. The report goes as close to suggesting that the pilot and the company have not been complete with the truth as their not apportioning blame policy allows. In this instance the ATSB has done what they are required to do. Investigate a serious incident to ascertain the facts and then issue recommendations to avoid a similar circumstance resulting in a fatal accident in the future. Hopefully other operators and pilots will learn from the incident as well.
I get that LHI, like Norfolk, is a place where the niceties of plenty of alternates with diversion fuel to go there are not available. However circling approaches in non-circling areas and marginal to non-existent VMC is going to kill you eventually, regardless of its location. Let that be your lesson from this report.
