2SER is a non-profit radio station in Sydney, New South Wales, Australia, broadcasting on the frequency 107.3 FM. It is a member of the Community Broadcasting Association of Australia. The station has a metro-wide license and broadcasts a mix of programming styles: specialist music, general magazines, and specialist talks. It currently broadcasts a variety of talk shows on topics such as science, current affairs, health, conservation, publishing, gender and queer culture, music, the arts, and theater.

2SER has two studio locations in Sydney. The 'Macquarie University' location has a recording and broadcasting studio, so the map location shows this assuming this would have been where a live session was recorded.
