It would have been 14 on 14 if the ref picked up the Wallaby indiscretion.
The Wallabies also benefitted from being over the ball. They just weren’t there enough to get the calls. Foketi got one almost immediately after getting on. And he was right about the calls. Fijian players were very accurate and had hands on the ball, lifting it and showing him a picture of Wallabies not releasing. The Wallabies paid the price for not having the same accuracy.
Lomani got called for not retreating from a kick as soon as he got on and it was very costly because Fiji were in a great attacking position from that kick.
Fiji were too good and wanted it more. The ref had nothing to do with it.
