Strong winds and a surging swell provided challenging conditions for the remaining eight surfers on the final day held at Smiths Beach.
Pinkerton eliminated Victorian and reigning event champion India Robinson in the second Semifinal on her way to the final. Silva locked in an 8.00 point ride and a 6.25 in the Final through a series of tight turns in the pocket in the rough seas.
"I'm over the moon to win my first-ever QS and make my first final," said Silva. "I'm so stoked, I just want to keep the momentum going. It was pretty challenging out there today, to be honest. I was hoping we would keep running at the Penguin Parade but I just had to adapt and make the most of what we had. I'm heading to Port Stephens for my first QS6,000 event next so I'm super excited to get up there and hopefully make some heats."
Placing in second was Kirra Pinkerton who could only manage a 6.55 and 5.00 in the final.
"I'm just stoked to make the final and come up against my good friend," said Pinkerton. "I've been to Australia quite a few times but this is my first time to Phillip Island. The waves are super fun down here and there always seems to be swell which is awesome."
The Men's side of the draw saw an all Australian affair with eventual event winner Lucas Wriceeliminating Ethan Stocks before facing off against good friend and traveling partner Dylan Moffat (North Narrabeen, NSW) in the Final. Moffat eliminated Victorian Cahill Bell-Warren in the second Semifinal.
The final was a tight affair with Wrice locking in an excellent 8.00 point ride backed up by a 6.90. Moffat fell agonisingly short finishing with a 7.25 and 7.45, just 0.2 of a point shy of the lead.
"I'm really happy," said Wrice. "I have had a few decent results over the past year but haven't been able to make a win so I'm stoked to finally crack one. It was super fun staying with Dylan and then getting to surf in the final together. We are good mates so it's always good to surf against each other. I have surfed a bit down on Phillip Island before at Pro Junior events and I really like it. There are always good waves and it's a beautiful place."
In making the final, Moffat scored his highest placing in a QS this year.
"The goal is always to win, but I'm glad we are down here on Phillip Island, getting some fun waves and making a few heats," Moffat said. "I was chatting with Lucas at the start of the event about us both making the final so for it to happen and to be such a close heat was awesome."
The 2019 Phillip Island Pro men's and women's events will run from November 7 - 10.
