Would payphones be more secure than private phones? Payphones are few & far between in Sydney, so third parties who want to listen don't need to bug too many of them.
Using a personal phone to contact the security services provides a direct link between that person and the security services to anyone who can access phone records. Using a payphone (probably) at the very least increasing the cost of establishing such a link (to identify the individual, you need listen to the call, which is more work and may be obscured by any OPSEC requirements that can be established over the phone, or have access to some other records [phone location records if the person is carrying a mobile phone at the same time, or CCTV footage from the area]).
Also, a new phone with sim card is only about $30 in a petrol station. You would be better off going to a random petrol station, buying a new phone/sim, and disposing of it after the call. Preferably by removing the battery, then taking it to some other remote place and destroying it, then take it home and dump it in your neighbours trash. Depends how paranoid you are, but if you're becoming a spy...

Actually you just need to stay nearby - the phones are used to rarely that anybody who uses one is probably a spy.

In Australia you need to provide ID to buy a sim card / new phone.
So ridiculous.
