That card put him in danger of missing yet another cut. Atwal, tied 129th, is having problems with his form this season and has missed cut in two of the four starts with a best of 45th.
Bhavik Patel, an American of Indian origin, continued his good form and carded a flawless three-under 68 in the opening round to be tied seventh, alongside Daniel Chopra, whose father is Indian. Chopra carded an eventful 68 with six birdies and three bogeys.
Leading the field are local Brendon Todd, Argentine Rafael Echenique and Korea's Whee Kim. They all shot five-under 66 each to share the lead.
Kiwi Tim Wilkinson, Brenden Pappas of South Africa and Michael Putnam of Washington are tied at four-under 67.
Seven more players, including former Bulldog Ryuji Imada, 2010 champion Martin Piller and leading money winner Edward Loar - are in seventh place, two off the pace.
