There are about 25 more plants yet to flower this season - mostly Aussie natives / hybrids, based on Den. kingianum and speciosum. SO, in short, cold-growing orchids that don't need any supplementary heat in winter to get them through a pretty chilly Canberra winter. We regularly get below 0 degrees C (32 F), although the coldest I've recorded in the unheated greenhouse is right on freezing. But no sign of any cold damage this season.
