Was listening to Melbourne Centre around midnight (S.A. time) last night, & there were at least four aircraft heading to Perth that had to divert to Adelaide due to weather in Perth & also their fuel status. It was like a domino effect - after the first one announced his intentions at least another three followed in fairly rapid succession. Lady ATC was doing a great job of sorting them all out, as well as dealing with other aircraft that were asking for ride reports.
