The commentary on the Foxsports replay put it at "over" 4000 in attendance. They said if you fill the hill it's easily 3000-4000 and with everyone else it was more.
Good crowd I guess. Not sure of the venue but I'm taking my kids to the next game so I guess we will see what it's like. I am surprised there isnt a stand there and why dont theu set up some temporary stands on the opposite side to the hill like the did at Lark Hill for the Australia Stockman vs Western Force game?
Here is a good example of the stand at Lark Hill during the Force vs Stockman game..
