Aiava clinched the ACT Claycourt International with a 6-2 6-2 victory against Japanese talent Risa Ozaki at the Canberra Tennis Centre on Sunday.

It was Aiava's third final on the Canberra red dust, while she's also played a hardcourt decider in the capital, but this the first time she'd lifted the trophy following a near-flawless performance.

The 18-year-old said the scoreline didn't reflect the contest and was pleased she was able to finally finish the job in Canberra.

"I felt pretty good, the match was tougher than the score looked and I’m just really happy to get the win in Canberra finally," Aiava said.

"Today was more mental more than having a game plan and I'm just glad I kept my cool during the match and everything worked out.

"It's my first title this year, I haven't got off to a good start, so it's good to get the win under my belt before I go to America. I'm feeling confident."

The world No. 202 also played in the doubles final, alongside Ellen Perez, and despite winning the first set, the Australians fell to Tereza Mihalikova and Naiktha Bains 4-6 6-2 10-4.

"Those girls played pretty well so you can't do much about that," Aiava said.

Aiava flies to America on Wednesday for a month and will first play in the WTA Charleston. She'll also play doubles alongside Astra Sharma.

"I think I'm going pretty well at the moment, I'm working more on my fitness base and am looking forward to going to America," Aiava said.

"My goals this year are just to go do deep in the draws in the bigger tournaments and look after the body as well.

"I'm still 18 but pretty much have to be like 30-year-old on tour, but that's what comes with tennis.  I just stay in my room by myself and watch TV shows."
