McIntosh was born in Victoria, Australia and hails from the eastern Melbourne suburb of Nunawading.

On arrival back to Melbourne a few days later scans showed how bad an injury she had and went straight into surgery with Greg Hoy for an Elbow reconstruction.

Sitting in the stands at the Sydney Olympic Games Cecilia vowed she would make it to the big stage.

But 3 months to go before Athens and the pain was too much and Cecilia just couldn't get a decent pre-departure throw out and needed to go back into surgery for a full shoulder reconstruction meaning she would miss the 2004 Olympic Games.

Trying desperately hard to return to her best and qualify for the 2006 Melbourne, Australia Commonwealth Games Cecilia just couldn't get over the shoulder injury that had plagued her for 4 years.

In the first of the 2 exhibition matches for 2015 McIntosh tore her ACL on the MCG at the 14-minute mark of the first quarter and would take no further part in the game.

Having had Julian Feller reconstruct the knee 3 weeks later, McIntosh was back at training straight after surgery in a well documented series of Road to Recovery videos.

10 and a half months later on 1 May 2016 McIntosh played her first game back for her VFL club Melbourne University in a match winning performance.

McIntosh later played for the Melbourne side in the Women's All-Star match at Whitten Oval in September 2016.

[8] She made her AFLW debut in round 1, 2017, in the club and the league's inaugural match at IKON Park against Carlton.

[4] McIntosh and Astrid Loch-Wilkinson had to appeal to the Court of Arbitration for Sport in order to gain the right to compete at the 2010 Winter Olympics because the International Bobsleigh and Skeleton Federation had not allocated a spot for Oceania during the qualification process.
