Tiger Woods shot a three-over-par 75 to fall six shots off the lead heading into the final round of the Australian Open.
The 14-time major champion took a one-shot lead into the third round but went over par for the first time this week to trail John Senden by six shots.
"I got off to an awful start," said Woods. "On the first nine, the greens were way firmer and I played more break and left everything on the high side.
"Then I made a concerted effort on the back nine to hit low lines and left everything low.
"There are a few easy holes you need to take care of and I didn't do that."
Senden, a 40-year-old Australian, equalled the course record at the Lakes Golf Club by shooting a bogey-free 63 that included seven birdies and an eagle at the sixth.
