Based on the search results, it is not possible to determine which radio station is broadcasting the AFL today. However, there are several radio stations that broadcast AFL games, including K rock 95.5 (3GL), ABC Grandstand, NIRS “AFL Indigenous Broadcasting”, Macquarie Sports Radio, and AFL Nation. The AFL Broadcast Guide on the official AFL website provides a television and radio broadcast guide for the Toyota AFL Premiership Season, but it is not specific to todays games. It is recommended to check the websites or social media pages of these radio stations to see if they are broadcasting the AFL today.
