2/3 of a lifetime ago I regularly used to operate into Melbourne in the middle of the night. It was well known then that if there was fog in Melbourne, runway 27 afforded you the best chance to get in. Not sure why, but experience had proved it to be true.
Fast-forward a few years and there I was sitting at the threshold of 27 with 2 or 3 runway lights in view. I had to wait a while as it was below the take-off minima. Meanwhile, 3 jets from a couple of our northerly neighbours, managed to land on runway 16 whilst the 'locals' held or diverted or both.
My, how the weather patterns around 'Tulla' must have changed in those few years!
A comparison of various airline's diversion rates due to low vis at Australian ports would be interesting.
