It would be my guess that the government very very quietly has withdrawn the security guards from the bridge as a money saving exercise. I admit it has been a good couple of years since I last cross the bridge by any means of transport.

Nah, they're on 466.675MHZ in P25. Shared with REX at the airport.
It somehow slipped being licensed in ACMA though.

Re: Harbour bridge security
466.675MHZ is only registered to REX now. Based on ACMA anyway.
Re: Harbour bridge security
Hmmm - me thinks "unlisted" frequency.
Mind you it is rather boring most of the time ... when it was on the GPT 800Mhz .... about a dozen phonetic callsigns .. rotating guards around different locations ... got the impression from the two references below that anybody who trespassed was picked up by rovers/ CCTV / movement detectors early on in the piece

Mind you didn't stop Jeremy Clarkson taking the piss out of some poor guard standing under the bridge

Re: Harbour bridge security
So if you enter this into your digital scanner as a P25 system you will pick them up?Nah, they're on 466.675MHZ in P25. Shared with REX at the airport.
There not encrypted are they?
Thanks, John.
