Former Olympians have lashed out at US Masters-winning golfer Adam Scott for being too busy to represent Australia at the Rio Olympics.

Outspoken swimming legend Dawn Fraser led the wave of criticism against Scott, who confirmed on Wednesday that his playing schedule and family life meant he was unable to compete in the newly-added Olympic sport.

Fraser wrote on her Facebook page that she worked three jobs to fund her Olympic dream, while Scott was driven by money and lacked pride in his country.

"Well done Adam, great to put your country on hold so that you can fulfil your own schedule," Fraser wrote. "How much money do you want in life? (You're) not showing much for your country."
