Lee Westwood has set his sights on glory at the Perth International
How does it work?
The first two rounds were run as normal, which saw the 156-player field reduced to 65 at the cut.
After that, there will be a matchplay style event on Sunday.
Former Masters champion Danny Willett and Lee Westwood are among the English contingent competing.
Westwood heads to Australia after finishing in a tie for 11th at the Maybank Championship.
And he is relishing the unique format that awaits him in Perth.

He said: “I do well at stroke play and match play, so it's nice to see somebody use their initiative and combine the two.
“I watched a little bit on TV last year and it looks like an exciting format.
“It's a format where you've got to adopt a more aggressive approach. It's no good edging your way in.
"I think you've got to come out as fast as you can and obviously make the cut on Friday night, but then getting in that top 24, so you might as well be aggressive and go for everything.
“It's just so fast and furious, six holes, that you probably won't have that much time to think.
“So it's just a case of coming out and hitting good shots early on and making putts."
