An opening round of 69 has Scott in a share of 10th place at 3 under and five shots behind the leader Patrick Reed.
Although five shots behind Reed, Scott is only three shots out of second place as the events enters day two tomorrow.
The highlight for Scott was a near eagle at the par 5 1st hole which was his 10th of the day having started his round at the 10th.
He would then drop a shot later in the round after getting to 4 under but he is well enough placed to build on his solid start.
In the windy and demanding conditions 26 of the 77 player field broke par, world numbers one and two, Brooks Koepka and Dustin Johnson, at even par and 2 over respectively, the disappointments of the day.
Day too, was going along nicely until an agonising double bogey at his final hole cost him the chance to share the 10th place with Scott.
Day, who finished 5th last week in Korea, recovered from an early bogey to reach 3 under for the day through 15 holes before disaster struck at the last.
Reed has played this event on four previous occasions but aside from a 7th place finish in 2015 his record here has been less than impressive but he is excited about his first event of the new season.
"It feels great. To be able to come out here and to be the first event back and to feel like I hit the ball really solid, said Reed. "I had full control, especially with how windy it was today.
"It felt really good because if you can go out and shoot rounds like that in these kind of conditions, you know you're going to have confidence when the wind dies down and there are perfect conditions out there.
"I really just need to keep on taking it day by day and try to shoot the lowest round I can each day. Hopefully I'll shoot a couple more of these rounds, I think that will help me out."
Of the other Australians in the field Adam Bland is 27th at even par, Brett Rumford 41st at 1 over 73, Jason Norris 49th, Jason Scrivener 59th and Cameron Smith 68th.
New Zealander Ryan Fox is tied for 16th at 2 under par.
