A NSW government program providing therapy dogs to distressed witnesses and other visitors in public areas of the state's courthouses would be expanded to allow child sexual assault survivors to be accompanied by a support animal while giving evidence, under a plan being considered by the Attorney-General.

The Berejiklian government kicked off a nine-month trial of the comforting canines at Manly Courthouse last year and, following an "overwhelmingly positive" response, expanded the program this year to Sutherland, Gosford, Burwood and Campbelltown courthouses.

NSW Attorney-General Mark Speakman, pictured outside Gosford Courthouse, says the state government is "exploring the potential" for more child sexual assault survivors to access support animals during their evidence in court.

The program will be extended again over the next six months to Wagga Wagga, Taree, Nowra, Orange, Lismore and Goulburn.

Under the existing program, labradors and volunteer handlers from Guide Dogs NSW/ACT "deliver their services in courthouse waiting rooms, domestic violence safe rooms and courtyards", Attorney-General Mark Speakman said.
