I don't know if there are two different clones of this rose around, or two different roses, or if its behaviour depends on climate. The one I got was called "New Guinea China" and had provenance Someone who said it grew well in New Guinea -> Lionel over the mountain-> Leonie Kearney -> me -> Petticoat Lane (in Sue Zwar's care) and the Blakiston Schoolhouse Garden.
For Leonie, in the foothills west of Brisbane (subtropics), it isn't as double as in Warren's photo taken on Manus Island. Colour looks nearer red.
For me, Mediterranean climate, zone 9b, and for Sue Zwar, further south, probably zone 8b, the central ball of petals doesn't open fully, at least in spring. Between red and pink, and with an occasional white stripe consistent with China ancestry. My young potted plant was thornless apart from some hooks on the back of the leaves, but Sue's plant has prickles on a watershoot. See photos.
It also seems less healthy than on the equator., with both Leonie and Sue noting some black spot.
It strikes readily from cuttings, and flowers at a very young age.
