The Flying Fijians side to face Australia in their Rugby World Cup opener will be known today.

Head Coach John McKee will release his match-day 23 to World Rugby later this afternoon.

One of the interesting calls that McKee will make is whether to start Semi Kunatani or Peceli Yato at openside flanker knowing that Michael Hooper and David Pocock are sure starters for the Wallabies.

Whether Lepani Botia or Jale Vatubua wears the number 12 jersey will also be revealed today, while Nikola Matawalu is likely to get the edge over Henry Seniloli as the replacement halfback.

Sam Matavesi, Campese Ma’afu, Leone Nakarawa, Dominiko Waqaniburotu, Viliame Mata, Frank Lomani, Ben Volavola, Semi Radradra, Josua Tuisova, and Kini Murimurivalu are expected to be in the starting lineup.

Peni Ravai, Eroni Mawi, Alivereti Veitokani and Waisea Nayacalevu are expected to be in the 23 member side.

Head Coach John McKee says he has been quite impressed with the player’s efforts at training in the last few days.

“Very pleased with the outcome of training yesterday the boys trained really well the boys really and I can see the focus has really lifted this week as you would expect to come towards our opening rugby world cup game tomorrow morning as I say very important session the final rehearsal of our plays before we travel across to Sapporo and our final preparations and our captains runs before the match against Australia.”

Meanwhile, Wallabies lock Adam Coleman says they need a good start to their World Cup campaign but Fiji is a quality side.

“I think if we talk about momentum it’s important to start our campaign well before moving to the Welsh game you know they are a quality side very physical love to throw the ball around and it’s going to be indoors so it should be some great running rugby there’s a good buzz around the team so the boys are keen to get out there.”

The Flying Fijians take on Australia at 4:45pm this Saturday followed by France and Argentina at 7:15pm before the All Blacks meet South Africa and 9:45pm.

The World Cup kicks off tomorrow with hosts Japan playing Russia at 10:45pm.
