I am interested in what you say as there are a number of High Court authorities that say otherwise.
Which are, on their facts, of limited relevance to you.
For example,
Kuru is about police powers more generally,
and about whether or not new facts (or new offences) arising during the licensed entry
give rise to a separate power to remain.
By comparison, the relevance of
Plenty depends in part,
on whether or not this was a "private" notice - from, say, the landlord
(even if given in accordance with the above act),
or from "the Crown" - such as if it was a court order.
Your matter seems to be about a civilian, and a civil matter,
which, again, tends to make
Plenty less relevant.
It's also helpful to contemplate that an occupier's right to revoke a licence
does not operate to contradict an authority to enter arising at law from elsewhere
(because the latter does not involve a licence from the occupier).
If it did, then a search warrant would never have effect,
not would a power to enter land held by, say, a firefighter,
or even a meter reader.
Nor will it operate to enable contempt of court.
