B-Rock 99.3FM (call sign: 2BXS) is a local radio station in Bathurst, New South Wales, Australia. It broadcasts on 99.3 megahertz on the FM band, from a transmitter in Bathurst, with a power output of 10 kilowatts (10,000 watts) and callsign 2BXS.

Its callsign meaning is:

• 2 (a prefix for New South Wales radio stations)
• BXS, an extension of its sister station (2BS)'s callsign. However, this callsign is never heard on air.

Its on-air name, B-Rock, is named for Australian motor racing legend (and nine-time Bathurst 1000 winner) Peter Brock,^[1] but can also be known to be short for Bathurst Rock (or Rocks).

It is owned by Bathurst Broadcasters Pty. Ltd., a privately held company, owned by Bill Caralis's Broadcast Operations Group, who also owns sister station 2BS Bathurst.

It began broadcasting on 2 December 1996, as a supplementary FM license in the Bathurst district.

B-Rock's format was hot adult contemporary (rock), with a core audience of up to 39 years. Its programs are produced locally, and features competitions, comedy, requests and national news which airs on the hour from 7 am to 5 pm Monday to Friday.

In January 2025, BOG changed the format of B-Rock to Top 40 (CHR) in an attempt to appeal to a wider audience, particularly younger listeners. In a statement on Facebook, B-Rock stated that the Rock format had become niche in many Australian markets. Any rock music played on B-Rock now mostly comes from BOG's 80s to Now music log, which is also heard on stations like NEW FM 105.3 Newcastle and Roccy FM 93.9 Young.
