Millar will fly to Tokyo on Sunday night just hours after completing his fourth round at Twin Creeks.

He can force his way up the leaderboard with a strong finish, but his hopes of victory are all but gone after Min Woo Lee, Justin Warren, Josh younger and Travis Smyth blitzed the course to breakaway from the rest of the pack.

Millar shot two-under on Saturday to be in a tie for 26th at six-under par, 11 shots behind Lee and Warren and 10 behind Younger and Smyth.

The 43-year-old has his eyes on a bigger prize, shifting his focus to Japan. Millar will skip the Australian Open in a bid to earn his tour card in Asia and set up his future.

Millar has been battling a back injury for most of this year, but has recovered to give himself a shot of joining the lucrative circuit.

"I'd really love to get through and get a card. I think you need to finish in the top 25 over six rounds to do so," Millar said.

"But I'm looking forward to giving it a crack ... my back is holding up so we'll see what happens when I get there.

"I'm a bit disappointed not to be playing in [the Australian Open], but I have to look at Japan as the potential of getting a year's work."

Chris Campbell and Josh Armstrong missed the cut at the NSW Open.
