ATIS is the terminal information as others have said, and it looks like someone has set the radio up with a short cut for 126.25
Silly thing to do because if you are moving around the ATIS for another location will usually be different. e.g. if you flew from that location to Moorabbin and broadcast on 126.25, you'd get nothing because the Moorabbin ATIS frequency is 120.9
Getting your en route information right is another reason for taking the time to do a flight plan.
