Fog
not an issue, and yes he may have opted for familiar and avoiding the scorne of landing at SRI, but at least you can walk away saying get F

I also feel that he may have tried to be "gentlemanly" and stay out of CTA for the last bit as the folk in Sydney seem to scare off folk so much it becomes hard not to descend early rather than arrive over the field at say 4000'.

As for wrong engine.........good point but ohhh dear!
