What an interesting discussion.
On one hand we have complaints about Melbourne operating on a single runway causing delays. On the other, complaints about getting assigned a runway that isn't into wind or the shorter option.
If everyone required the long into wind runway then every day would be a single runway day and we'd all be screwed.
If you were flying your 767 into YSSY and 16L was the only option, would you divert to somewhere with a 3km runway?
Unfortunately we don't have long parallel runways everywhere so we make do the best we can.
