They have an advantage: Cheika knows everything about Aussie Rugby, he worked analyzing Super Rugby and even coached some of the players. I'm not sure if Rennie has that knowledge about Argie Rugby
Eddie Jones has beat the Wallabies 10 times since 2015, so that's a HUGE advantage IMO
You know Cheika doesn't analysis the opposition. So he only knows the 2013-15 Tahs and 2014-19 Wallabies. You can safely assume he knows 0% about any other players besides those two teams.
