Lydia Lassila

In 2020, Lassila returned to appear on Australian Survivor: All Stars, being eliminated via a fire challenge against opposing tribe member Phoebe Timmins on Day 18.

In 2018, Lassila appeared as a contestant on Australian Survivor: Champions vs. Contenders, competing in the fifth season of the competitive reality television series Australian Survivor as part of the Champions tribe. In the beginning of the game, Lassila dominated in challenges, winning for her tribe in many instances. Lassila made very strong relationships in the game, notably with fellow contestants Mat Rogers and Shane Gould. Come the merge, Lassila was seen as a physical threat by many contestants and was voted out in 12th place.

At the beginning of 2017, Lassila returned to competition in a bid to return to the Winter Olympics for 2018. On 3 February 2017 she won her first World Cup event since 2014, clinching a close fought victory ahead of Kiley McKinnon (USA) and Xu Mengtao (CHN) at Deer Valley. She then went on to obtain the second and the third World Cup wins at the end of February in Minsk and in the beginning of March 2017 in Moscow.

Lydia is the subject of a feature documentary film called The Will To Fly that chronicles her life and sport pursuits. The film was released in Australia in 2016 to much critical acclaim. The international release is intended for 2017.

On 20 October 2010, Lassila was awarded the prestigious 'The Don' award by the Sport Australia Hall of Fame, which recognised her ability to inspire as well as her achievements during 2010, including her gold medal performance at the 2010 Winter Olympic Games.

At the 2010 Winter Olympics in Vancouver, Lassila won gold in the aerials, getting Australia's second gold medal for the games after snowboarder Torah Bright won gold in the halfpipe, also at Cypress Mountain. This medal was also the second gold for an Australian in the aerials at all Winter Olympic Games, after Alisa Camplin in 2002. There was a lot of pressure and hype from the Australian press for Lassila to do well as world number one. She was in second position after the first jump of the final, before posting the highest scoring second round jump. The leader after the first jump, Xu Mengtao, had the last jump, but scored more than 25 points below Lassila's second jump to fall down the rankings into sixth, due to a failed landing. Lassila had a combined score of 214.74, beating second placed Li Nina with 207.23 points. Australian team-mates Jacqui Cooper and Elizabeth Gardner finished 5th with 194.29 and 12th with 86.70 respectively.

Lassila made her comeback to World Cup competition 16 months later in China in December 2007, collecting a silver medal in her first event.

She ended the 2007/08 season ranked second in the World Cup standings, and then went on to win her first World Cup title in the following 2008/09 season.

In June 2005, Lassila suffered a ruptured anterior cruciate ligament (ACL) and underwent radical knee reconstruction in which a cadaver's achilles tendon was grafted into her knee to replace her damaged ACL. This allowed for a faster recovery and a swift return to the slopes in time for the start of the 2006 Winter Olympic Games in February.

Lassila completed her primary schooling at Our Lady of the Immaculate Conception Primary School in Sunshine, Victoria, and completed her secondary education at Methodist Ladies' College, Melbourne and Westbourne Grammar School. She completed a bachelor's degree in Applied Science (Human Movement) at RMIT University. She is married to Lauri Lassila, a Finnish former professional freestyle skier, whose career included placing 2nd in moguls at the FIS Freestyle Skiing World Championships in 1999. She gave birth to her first son in 2011 after winning Gold at the 2010 Vancouver Winter Olympics. Her second son was born in 2015 after the 2014 Sochi Winter Olympics where she claimed bronze.
