Fox Sports have the rights but 9 Gem is broadcasting all Aussie games as well as 'selected' others. It is not on free to air every night and looks like tomorrow night (Thursday) is the next freebie broadcast....Aus vs West Indies. As mentioned by others, it is screening at awkward times. Telecast of day matches starts at 7pm with about 1/2 hour of talking sh!t then play starts. The match finishes around 3am if it goes the distance. Day / night matches start around 11pm and I would guess go to around 6am. If you are keen getting up a bit earlier than usual may be a better option.
Cheers
