Have the Telstra tv box on our TV and used it for Foxtel now last year, worked fine. It has already downloaded the Kayo app automatically for use. Haven't checked it out yet but certainly will before the footy season starts.
Interestingly I rang the club yesterday to enquire about the prices for GFG. Was told that I wouldn't get the packages relating to seating on level 2 and was recommended Demons seats plus. No mention of them being sold out so I sent the Cheque off today.
