Katrina Munting sued the state of Tasmania and her former Rose Bay High School science teacher Marcus James Pollard after he abused her in the late 1990s.
He was ultimately sentenced to three years' jail for his crimes after pleading guilty in 2020.
Mrs Munting claimed in the Supreme Court of Tasmania she was unable to reach her full potential because of the abuse and Justice David Porter ultimately accepted the state - as Pollard's employer - was vicariously liable for it.
Justice Porter awarded Mrs Munting $2,016,135 in damages on June 17, with about $1.38 million accounting for her lost past and future earnings.
The judge amended the figure to $2,129,595 on Monday after Mrs Munting's lawyers pointed out he miscalculated interest she was owed on lost income.
Mrs Munting's abuse was brought to the attention of the school's then-principal and senior education department figures in February 2000, the judge found.
Soon after, Pollard was effectively suspended and he resigned in April 2000.
Tasmania Police was not notified and no complaint was brought to their attention until Mrs Munting began criminal proceedings in November 2018.
