I wouldn't knock him. Out this way, there are very few alternate airstrips, and plenty of mountains. Without us speculators knowing exact layout of the fog, probably he may not have had the luxury of clear air to a better landing area.
I'm well South of Sandfy, and he was heading North of there. Believe it or not, I believe he saw different sky from me.
Two days ago we had cloud that often dropped to ground level. I heard a chopper. Following the sound, I got a glimpse of it way below my verandah, following the river between 500' hills. I estimate he was no more than 100' agl. The weather was similar here yesterday. Today has high cloud base. Where he was would have been different but my point is that Tassie weather can change very suddenly, and locally. I prefer to give the pilot credit for assessing weather at the time, but getting caught out with a unpredictable change. BOM cannot predict everything.
And although the outcome wasn't perfect, it was very good.
