hi there chook,
my guess is its a cymbidium, based on the "dural" part of the name, but a pic will help.
If it is, and you are in the sydney area, this is how I have mine -
Outside
Morning sun
Water - in summer every 3 days or so, winter maybe once a week. *important - try to water in the afternoon in summer, it cools the bulbs and will assist with next years flower formation
Feeding - Weakly Weekly. I use half stength miracle grow, something like thrive or aquasol is fine.
Cant help with the red spider mite, have never needed to treat for it.
Hope that helps, and BTW, welcome to OB
