We dove the Yongala for a couple of days last Nov. I'd definitely say an extra day is worth it as by then you will know your way around the wreck and can concentrate on the areas that interest you most - we would have happily dived it many times more. I think we dove on a Sat/Sun but since there's only a limited space on the boat it was never busy underwater. Since it was the weekend on one of the days they ran an afternoon boat which meant we had an opportunity to dive at two different times of day/tide which was interesting as the fish behaviour was different each time.
You can see a video I made of our dives in the following thread:
What's so great about the Yongala?
Whilst you are in Townsville you should definitely try and make it up Castle Hill to watch the sunset one evening and watch the parade of locals cycling, running and walking up the hill for their evening exercise.
