Perth's season opener against South Sydney is unlikely; Rabbitohs prefer hosting Roosters in Round 2 instead.
Plans for Perth to face South Sydney in their history-making season-opener are unlikely, while Melbourne ask to host Canberra for their final home game to pay homage to coach Craig Bellamy.
It comes as Penrith push to host a first game at their new stadium on the Easter Weekend - specifically Good Friday - in what would be a round-five fixture.
As the countdown begins to the Bears' anticipated return to the NRL, the Rabbitohs looked destined to travel to Perth in Round 1.
However, those plans are now unlikely given South Sydney's desire to host arch nemesis the Sydney Roosters in round two at Allianz Stadium.
The turnaround time would have been too short for the Rabbitohs if the round-one game was to be on a Saturday or Sunday.
