Thunebro began playing at the age of six, eventually rising to the youth club IK Viljan. She advanced through the Damallsvenskan to one of the top-tier teams Djurgårdens IF. With Thunebro on the team, Djurgården won the Swedish Championship in 2003 and 2004. Djurgården also won the Swedish Cup in both 2004 and 2005, securing qualification for the UEFA Women's Cup. In 2005 Djurgården reached the final but were beaten by Turbine Potsdam.
After twice being voted the best defender in Sweden, Thunebro joined FFC Frankfurt in 2009. She extended her contract with the German club for another two years in April 2011.[6]
After playing only three games in the first half of the season she left Frankfurt in March 2013 to join Tyresö FF in Sweden. She aimed to get more match practice ahead of the UEFA Women's Euro 2013 in her home country.
After one season at Tyresö she moved on again, to newly promoted Damallsvenskan club Eskilstuna United DFF. In announcing the transfer in December 2013, Thunebro admitted she moved to be based closer to her family.[7] After the 2015 season in which Eskilstuna finished as runners-up to FC Rosengård, Thunebro made the difficult decision to retire from playing. Coach Viktor Eriksson thanked Thunebro for her part in establishing the club in the top league and described it as an honour to have worked with her for two years.[8]
International career
A 3–0 defeat to the United States in January 2004 was Thunebro's first appearance for the senior Swedish national team. She had already collected 32 caps at Under-23 level, eight at Under-19 and 10 at Under-17.[9] She remained on the fringes of the squad but was left out of the selection for UEFA Women's Euro 2005. Thunebro travelled to China for the 2007 FIFA Women's World Cup but made just one appearance during Sweden's exit at the group stage. Returning to China for the following year's Olympic football tournament, Thunebro had become a regular starter in the team which reached the quarter-finals.
By 2009 Thunebro was an important part of an in–form Swedish team who were enjoying victories over Germany, Brazil and the United States. "Each year I've taken small steps forward," she explained. "I feel in great form now, but I haven't reached my peak yet."[10] At UEFA Women's Euro 2009 Sweden reached the quarter-finals only to be eliminated by Norway.
At the 2011 FIFA Women's World Cup in Germany Thunebro won a bronze medal with Sweden, who were beaten by eventual winners Japan in the semi-final. Third place secured Sweden's qualification for the 2012 Olympic football tournament in London. In September 2011 Thunebro announced her intention to retire from international football after the UEFA Women's Euro 2013 tournament in her home country.[11]
Following Sweden's second round elimination in Canada Thunebro quit international football. She had received only 15 minutes of playing time as the team failed to win any of their four matches at the tournament. Thunebro felt that she no longer had coach Sundhage's confidence and did not want to sit on the substitute's bench to make up the numbers.[14]

Thunebro enjoys playing golf and rides a motorcycle. Throughout her career she did not employ an agent.[15] Part of the reason she wore her trademark headband was to allow her grandmother to easily identify her while watching on the television.[16]
