Channel 9 can't show it.
It's not included in the rights deal 9 have, it's a seperate deal.
Fox Sports signed a 4 year deal for the game starting from last year.
And it's reasonable that Fox Sports does have a fair amount of exclusive content seeing as though they charge Foxtel/Austar $10 per customer, and Optus $8 per customer for the channel. If they show to much sport that is on fta, the providers will dump the channel - something Foxtel threatened to do 18 months ago unless Fox Sports lowered their fee (it was $11 per customer at the time)
