Help with AU native terrestrial orchids

[Foozil]

I have some problems with a few of my deciduous Australian orchids. This year, at least in the east, orchids that should be flowering september or later are flowering now. This is ok with the epiphytes, because they don't go dormant, but with things like oligochaetochilus that go dormant soon after flowering, I fear they will go dormant way too early.
So, my question is, is it alright for them to go into an extended dormancy period (e.g late august to march) or should I let them do their thing?
