New South Wales

 was a state in Australia that both Simon Griffiths and Nate Simms called home. Known cities or towns in the state included Sydney and its suburbs Parramatta and Glebe, along with Castle Hill. At least part of its southern border with Victoria was defined by the Snowy Mountains, which Simms once visited whilst lodging at Jindabyne. Polly Wright was known to have spent some time in the state. (PROSE: Invasion of the Cat-People)

The Eleventh Doctor, Kazran Sardick and Abigail Pettigrew also visited the state and had their picture taken in front of the state's signature landmark, the Sydney Opera House. (TV: A Christmas Carol)

In 1932, the Doctor, in an unknown incarnation — but almost certainly not his fifth — took five wickets for New South Wales, for which Donald Bradman played, at an unspecified cricket test. (TV: Four to Doomsday)
