Doey Choi has decided her time is now.

Choi played her final round as an amateur at the Australian Amateur Championships at Kooyonga on Friday.

Tomorrow she will make her debut in pro ranks at Corowa Golf Club in the inaugural Murray Regional Open.

It's been quite a journey through the amateur ranks for the Concord GC champ, who announced herself to fans of the sport in 2014 when, as a 14-year-old, she claimed the NSW Women's Amateur Championship.

She has since won titles across Australia and overseas, including the 2019 NZ Amateur Crown as well as representing Australia on several occasions.

"It feels like I was an amateur for such a long time," the always bubbly Choi said with a smile when asked about the timing of the decision.

"I couldn't do the same thing as last year, which was basically sitting around at home and doing nothing.

"Plus I have all these regional events."

Choi hasn't decided when she will head to the United States, saying she hoped to try her luck qualifying for the US Women's Open.

"I've got a start in the TPS (Tournament Players Series) at Bonnie Doon, Braith Anasta's tournament, then hopefully I will head overseas to go to Q-School in America," she said.

"I've got a friend I can stay with and there is a US Open pre-Q near his place, but with everything going on with the COVID virus, I will likely go just before Q-School in August.

Choi said it felt like a fresh start in the pay-for-play ranks and, as the new kid on the block, her expectations for this week are a little tempered.

"I'm basically a rookie again," she said.

"It feel's strange, but I'm looking forward to it.

"Especially after last year, I am really motivated to kick-start my pro career in a good way.

"I want to play as much as I can, do my best. Hopefully, by the end of the year, I can get status on a tour somewhere," she said with trademark grin.
