Optus won the rights two years ago so there has been ample notice. The FTAs were not prepared to go for the exclusive rights (one of the prices of equality), including ABC and SBS. It doesn't come under anti siphoning if nobody else is prepared to bid.
The ladies WC is now a standalone package and as such FIFA has put a standalone price on it. Will be curious as to what final viewing figures are. It hasn't really grabbed my attention yet.
