Connex trying to keep troublemakers off its station platforms?

["Paul Nicholson" <pnichol4@bigpond.net.au>]

Interesting item on 3AW this morning saying that Connex had wanted a charity
group to pay more than $4000 for the "right" to seek donations from rail
passengers tomorrow. The charity is raising money for deaf children.
It was reported that Connex had backed down and waived the fee.
Notices saying that station premises are for rail passengers only have
appeared on Connex stations in recent weeks.
How is this policed?
Wonder if there will be any problems for railway enthusiasts taking photos
from station platforms? I've always considered that station platforms are
"public" property and so long as you were taking your photo from a location
that is open to the pulic there shouldn't be a problem.
Often in the United States you are asked what you are doing if you are
taking a photo from a station platform and you are reminded that it is
"private" property.
I presume the primary reason for Connex putting up the signs was not aimed
at railway enthusiasts.
