In response to the original post, I assume that the $1.60 was the correct price. I saw that dividend and was amazed as it was so much shorter than anywhere else.

But this is what I think might have happened. On Sunday, they were clearly having awful trouble and the approximate divs that were showing on screen weren't up to date, and they weren't changing. They were explaining this on the radio at the time. So what I think has happened is that punters saw a higher price for December Draw on Unitab compared to other totes and they all continued to jump on, therefore unknowingly smashing the price down to $1.60. Well, that's my possible theory anyway.
