Even harder? That's impossible, things could not have got even harder than they already are. I don't think it would affect the score much if they just decided to end the pitch at the half way line and play it entirely in our half, their half will be redundant apart from fielding kick offs.
I was once invited to an RU game (yes I know, but the booze was free) on a corprate jolly to see the North of England play the All Blacks. By half time they were out of sight and the snow started falling so the second half started with a pure white pitch. By the end of the game the pitch was still covered in totally virgin snow from 10 metres inside the All Black half all the way to their dead ball line. I know it's unlikely to snow in Melbourne but I think the same thing would happen if it did.
