$10K Nathan??!! How lucky are you?!
Well, pretty lucky, but it's not a scary as it sounds - their policy is/was to give people warnings, and only fine them on the second time or if they were total dicks.
Bike was rego'd and I was licenced, FWIW. I don't know, but I don't think that unreg/unlicenced would have made any difference in this case.
Trespass on catchment was $10,000 max back in the 70's but $1000 was generally the first offence fine (which would be $10,000 today given relative purchase power/wages). The max fine is $100,000 today and with that magic word 'terrorism' 'they' are much more active.
During the 70's and the trail riding boom it was common practice to have a light plane flying over the catchment on week ends and guiding rangers to the 'bad boys'. I've always kept off catchment for this and other 'social conscience' reasons.
Proving 'trespass' in law is fairly difficult. 'They' have got prove intent and/or that you refuse to leave when asked (being a total dick) - that would explain the 'warning'. Once a warning has been given proving intent is a lot easier second time around.
Be careful, there's a new offence called 'enter upon enclosed lands' - it is much easier to prove in law - caught doing the deed and offence commited - no fuss no mess in court for the rangers and no excuses for you

I got done unreg'd etc when I unwittingly drove a company ute unreg'd etc - $1300 first offence in NSW (the company paid
). I've test ridden the occasional race bike in the street on the occasional saturday night last minute prep, but minimal and never sprung
