"The game is in pretty good shape and I am putting well so, it was a nice solid round," said Bransdon.
"I didn't hit it as good as yesterday but 4-under is never a bad score."
Bransdon believes the secret to his past two rounds has been an improved putting stroke.
"I have always considered myself a good ball striker but the putting has been my Achilles heel.
"I saw Phil Hodge up at Coolum, he said that I needed an overhaul so we spent an hour or so on the putting green - I'm still doing what he said and its working."
Despite his solid lead, Bransdon isn't getting ahead of himself with plenty of golf still to be played.
"I am just going to go and play - its sounds a bit boring but I can't control what anyone else does, so I'll just play and see what happens. As soon as you start looking ahead, that's when bad shots come in, because you're not focusing totally on what you want to do at the time.
"You have a job to do out there with each shot and that's what I am going to do."
Bradley Hughes had another good round, posting a 4-under 68 to be outright second on 9-under the card while a further shot back are New Zealander Gareth Paddison and Victorian Leigh Deagan who each fired 5-under 67 today.
Shooting the score of the day, a 6-under 66, was Matthew Griffin and Matthew Millar moving them into the top-10 of the leaderboard. While Leigh McKechnie also shot 6-under the card to make the cut on the number.
The cut was made at 1-under the card with 54 Professionals and two amateurs through to the weekend rounds.
Notables to have missed the cut include Australian PGA Champion Daniel Popovic, Andre Stolz and Craig Parry.
Play gets underway in the third round at 8.40am tomorrow morning with the leaders out at 10.15am
