A young NSW woman remains in a serious but stable condition in hospital after she was allegedly doused with accelerant near an open fire.
The 19-year-old was airlifted from a property south of Wollongong to Royal North Shore hospital on Saturday for surgery on her arms, chest and stomach.
A hospital spokeswoman on Sunday said her condition had improved from critical.
Police believe the woman was standing by an open fire at a home in Koona Avenue, Albion Park Rail, about midday on Friday when she was doused with accelerant, which caught alight.
They say the incident occurred after she had a fight with a teenager with whom she had previously been in a relationship.
Police have charged a 17-year-old, who can't be named for legal reasons.
The matter was heard in a closed court in Parramatta Children's Court on Sunday.
