Aussie orchid

My King Orchid or Dendrobium speciosum has flowered brilliantly this year. It's also a bit early, it's not even spring. But it's been warm and dry. I placed this orchid in full sun for the winter so that helped. This orchid is going to outgrow it's stump soon and I think there are white ants in there...I'll have to get another tree stump to put it in. These orchids are often found in Brisbane gardens. They are endemic to the east coast forests of Australia and it's diffficult to kill them....
