I have seen a couple whilst looking under rocks and a friend has seen them crossing bushtracks at night(he had to scream at the driver to stop on one occassion......how would you feel if you were on a wildlife survey and you ran over an endangered species!). Basically they spend the winters on rocks and summers in the forests. If you do go looking for them please ensure any rocks are placed back exactly how you find them.....they have already suffered enormously from people smashing up sites and from the bushrock collectors. Someone is actually trialling placing artifially made rocks back into sites that have been stripped by bushrock collectors in the hope of stabilising Broad head populations. I'm not sure if they are active by day although I've heard reports of people seeing them basking next to crevices(I saw a Stephens Banded doing this once). I think they do most of their thermoregulation by shuffling around under rocks and inside hollow branches to remain at a preferred temperature.
Nephurus.....personally I DESPISE the term "flipping". I know it is well entrenched on American herpsites...but to me it invokes a completely carefree attitude to rolling rocks over with disregard to how they are replaced, if at all. I am sure you didn't mean it that way.
We have all been to sites, often sites we have visited for many years, only to find that others have been there and broken rocks, left rocks rolled on their backs or not bothered replacing them properly, and undoubtedly vacuumed up a lot of animals in the process! The seal a rock makes with the ground or other rocks is often quite critical for the animals that utilise them. Coming across sites like this is quite devastating. It takes little effort to put rocks and other cover back exactly how you found them. Apart from showing respect for the environment you are in, it pays off big time in that you can go back to the same places over and over again and still see animals.
I think on these forums there are quite a few people with little or no field experience and I think use of the word "flipping" only conveys a sense of disrespect for the environment. Field herping is a fantastic pastime but we should all ensure it is something that others can enjoy long into the future.
