Site: Sydney Airports Corp Site International Terminal SYDNEY AIRPORT
(Confirmed)
P25 487.25000 NAC 526 [Clear]
P25 487.35000 NAC 526 [Clear] (Seems to be Main Channel - "Control")
P25 487.65000 NAC 526 [Clear] (Recorded Loop Messages - "Duress Alarm @ T1 Main Screening Point")
(To Be Confirmed)
487.0500
487.5000
487.7750
Seems to be low-power, and will only pickup within a few km's of the airport.
The above frequencies were registered on the 02-SEP-11 - theres a couple of older ones from about 2006 in the 470~ range on that site too, but i've only listed the most recent additions.

So there basically using the same frequencies but in P25 mode.
Will just need to remove the analogue subtones programmed into my digital scanner then.

dated 11.AUG.2011
C4i was engaged by Airservices Australia to provide a national Emergency Response system for twenty airports around the country. The solution utilised the inherent distributed architecture of Alarmon, allowing assets anywhere within the national system to be accessed by operators at any of the airports.
Operationally this allows an operator in Melbourne to take control and manage incidents at Sydney Airport (geographically 1000 Kilometres apart) in times of incident. This provides the Emergency Response crew with additional resources in managing incidents, as all staff in close proximity to the incident can assist with the actual task of responding. Also, the Melbourne-based operator would be presented with all the communications assets of Sydney, including direct numbers, fire panel information, and procedures specific to that airport.
In times of emergency it is a crew’s rapid response and ability to provide resources immediately that will determine the seriousness and final outcome of an incident. The national system implemented in Australia uses technology to maximise use of resources already available at other airports and to minimize response times during crisis management.
