If you've put fuel on to hold until a condition is forecast to clear , why not stick with the plan? If not what's the point of the plan?
A wise pilot would put a sh1t load more fuel on than that required to hold until a condition is forecast to clear. So there would be no need to stick to your questionable plan in the first place. BTW I am not in any way speculating about the ADL Flights. We arrived over CBR at the time conditions were forecast to clear. It was not until at least 75 minutes later that aircraft were starting to get in with numerous diversions in the interim. We held for 80 minutes through out the period you would have had us busting minimas and doing an autoland. No thanks. Could have held for a further 40 minutes before having to divert to SYD.
