11.21.16 X Factor Australia 2016 - Grand Finale

So, did anybody notice that the order of performances in the Grand Final night matched exactly the finishing order of the competitors? Amalia performed first, then Vlado, Davie, and Isaiah.

Now the question is whether there is a causality connection, and if yes, in which direction? Did the producers throw Amalia under the bus but pimped Isaiah (and to some extent Davie with that RW duet) thus influencing the outcome, or did they order them this way because they knew they would finish in this order based on previous performances/voting data?

Would have Isaiah won had he performed first, despite delivering the best performance of the night with Halo? My gut says he would have lost. So I lean towards my second theory above, they heard the songs, saw previous results, and ordered them this way because that's how they expected them to finish anyway...

ETA: I am very happy about Isaiah's win, but based on that night's performances (and all performances before it), Vlado should have opened the show and should have finished 4th. However, I think Davie deserved the second place, and even had the better potential single.
