David McKenzie, 66, 66, 69, 15-under, 1st

"I bogeyed the first which wasn't my ideal start but from there through 10 holes I played, not quite flawless, but as good as I could hope for."

"I three putted 11 and it just seemed to get tight around the back-9."

"When I got to 12-under I thought why not shoot another 12-under. That was my picture, to shoot 12-under in the last two rounds. That means I need to shoot really low tomorrow."

"If I was coming down the last hole with a four shot lead then I would definitely think that's enough. But you never know what's going to happen. It's a golf course where you can quite easily make a couple of bogeys and someone else a couple of birdies and all of sudden you can be tied again."

Brad Shilton, 64, 70, 71, 11-under, 2nd

"The wind really got up on the back-9 for us. It was pretty late, you really only felt it the last couple of holes."

"I started pretty poorly today. I hit a few bad shots and missed a couple of putts that I might have made the last couple of days."

"I am pretty happy to finish off 1-under, I think I was 3-under in the last 10 holes."

"I was just trying to be patient really. I made the same bad swing three of four times in the first seven holes. I figured out what the issue was and managed to fix that and hit it really well the last 10-12 holes."

"He (McKenzie) played really well today, especially early on, if he does that again it will be pretty tough to catch him."
