If it bids aggressively for digital rights to RA, NRL and AFL to drive retention and acquisition of its customers, it could find itself competing against Foxtel, which would therefore weaken its own position in the joint venture. Optus doesn't have that complication. Foxtel last week pitched a 12-month offer to Telstra customers of a 40 per cent discount for its Kayo Sports streaming service, meaning a cost to subscribers of only $15 a month, equivalent to the price of an Optus Sport subscription.
