Hedwall added a second round of 65 to her opening 67 to win by four over NSW second season professional Emma de Groot who in turn finished one ahead of rookie Whitney Hillier.
Last year's Victorian Open winner, Joanna Klatten finished in 4th position.
"I love coming down to Australia to play," said Hedwall who flew in to Australia with her twin sister Jacqueline, last Wednesday to join the ALPG Tour event at Antill Park. "This is my first time to play in the ALPG Tour Pro-Ams and I loved this week (competing in two events) The Pro-am format is good for me because my playing partners are relaxed and I play well in a relaxed atmosphere. This is my second win in Australia and gives me great confidence heading into next week's event (the Bing Lee Samsung Women's NSW Open).
De Groot, a former collegiate player in the US system, has been in good form of late winning the Antill Park Pro Am on Wednesday and finishing in a share of 3rd at the Vintage Golf Club earlier in the week.
The ALPG will now play the NSW Open at the Oatlands Golf Club beginning on Friday when New Zealander Lydia Ko will seek to defend her title.
