Opposite on the other side of the road are garages - maybe that was fields in the days before everyone had a car, and thus was where the cows grazed, or maybe barns etc for hay storage.
All those garages and garden walls on the other side of Murat Street belong to the big houses on Adelaide Terrace.
Looking at an old map it looks like there could have been some pasture land behind Murat Street, on the corner of Picton Road and Wellington Street, on the site now occupied by the Church of Christ.
