Moore, 20, added a further near-perfect 9.43 wave to finish with a heat-high total of 19.43 and announce her credentials as a potential champion at the Australian event.
“I had so much fun in that heat,” Moore said. “I got great waves, had a lot of opportunity and got to perform. I’m in a really good place.
"I’m happy and have some really good people in my corner. Last week’s win in West Oz gave me some confidence but I’m just really excited to perform and hopefully the waves continue to improve.”
Sally Fitzgibbons also wowed in her first-round match-up, scoring a heat total of 18.07 as the Australian began well at the event she has won twice before.
“It feels great to be back in Bells,” Fitzgibbons said. “There’s something about the place – it feels like coming home for me and I love it. That said, there are certainly no easy heats on tour this year.
"I feel like my surfing has improved every year and I’ve had to work really hard to maintain the No. 2 spot. I’m motivated by how well the girls perform on tour and it pushes my performance too. The ASP World Title is the goal – it’s everyone’s goal.”
There was less cheer for reigning five-times ASP Tour champion Stephanie Gilmore as she was upset by Alana Blanchard of Hawaii.
“I’m not really sure what’s different this season for me,” Blanchard said. “I think I’m a lot more relaxed as far as getting results go. I’m also catching more waves this year and being a little more aggressive in the water. Really excited to get a round one win.”
And there was another upset when Nikki Van Dijk of Australia saw off both current number one Tyler Wright and Malia Manuel in a fiercely-contested round one encounter.
“Tyler (Wright) is such an incredible surfer and she’s had such a solid start to the year,” Van Dijk said. “To get a win over her, she’s the number one surfer in the world right now, is a huge confidence boost.
"I’ve been working really hard though so I feel like my surfing is the best it has been. I’ve had the wildcard into the event for a few years so I feel like I have a lot of experience here in competition. Hopefully that serves me well as the event continues.”
