Scott was elected to parliament at the 2001 state election, after working as an electoral officer for 16 years. She holds a dental nurse certificate.

According to Independent Member of Parliament Alex Douglas, "She was completely focussed on the needs of Woodridge residents, which in turn earned her the respect of her constituents.", which led to her being one of only seven Queensland ALP MPs being elected at the 2012 election.
