Script: SOUNDBITE: (English) Nathan Grey, Australia assistant coach

(Q: You can't go in undetected in this World Cup?)

"Look I think that's something that we can't control, we're very focussed on our improvement day by day. I know that does sound a bit boring, but it is really the absolute honest approach of what we're doing. We've got our session planned for today, we want to focus on the players improving their performance and their preparation today. So we can't control things outside of that, what we can control is how we train and how we prepare and that's our focus."

SOUNDBITE: (English) Bernard Foley, Australia outhalf

(Q: How has Saturday's performance affected the squad?)

"Yeah I suppose it just sort instills a bit of belief in what we're doing and the ground work that we've put in is paying off and I think it comes back to the coaching staff, how they prepared us and how they prepared the team to go out there and put in a such a polished performance on the big stage."

SOUNDBITE: (English) Nathan Grey, Australia assistant coach

(Q: Do you think the competition is worse off without the hosts?)

"Look at the start of the competition we knew that we were in the same pool as England and Wales and it was very difficult, so our preparation has been towards those games and that's the reality of the competition and as I said we can't control that. That's done now and we have to focus on our improvement and our next game against Wales."

SOUNDBITE: (English) Nathan Grey, Australia assistant coach

(Q: What are your thoughts on Wales, what is your impression of their performances?)

"Yeah they've been consistent. We've done a lot of work on Wales, you know, having a look at their set piece and what they offer on multi-phase. Obviously you can't give away any penalties with Dan (Biggar) being such as successful goalkicker, they'll really crucify you if you give them opportunities. So the key there is to try and put them under pressure and then backing the way and the style that you want to play the game and our preparation will be so."
