In 2005, Sydney TAFE student Lauren Huxley was brutally bashed and doused in petrol. She was just 18 at the time.
Her attacker, 39-year-old Robert Farmer, attempted to set her Northmead house alight.
Ms Huxley was left with permanent brain damage and spent six months in hospital recovering from the senseless attack.
In 2008, Farmer was sentenced to at least 20 years in jail for the crime.
Now, Farmer is expected to mount an appeal, The Daily Telegraph reports.
The publication obtained letters Farmer wrote last year from his cell in Wellington Correctional Centre to a pen pal in which he explains: โI cannot wait for my day in courtโ.
The letters detail his desire to appeal his sentence through Queenslandโs Griffith University Innocence Project.
Ms Huxleyโs mother, Christine, told 9NEWS that Farmerโs possible plans to appeal was a blow for the family.
โWeโre just so appalledโฆ that he can actually appeal this sentence. Itโs not right. He has no remorse for Lauren,โ she said.
โWeโve had to relive this many times, and we donโt want to have to relive it again.
Although Farmer asserted his innocence, DNA linked and a footprint matching his shoe were found at Huxleyโs home.
