Boxing organises competition by weight class — athletes compete against opponents of similar body mass. This creates theoretically fair competition by removing the extreme physical disadvantage of fighting someone significantly larger. Here's how the weight class system works in 2026 under the major boxing organisations operating in Australia.
Amateur Boxing Weight Classes (ABF/Australian Boxing)
Amateur boxing in Australia operates under the Australian Boxing Federation (ABF) and NSW Boxing for NSW athletes. The weight categories align with World Boxing's amateur classifications:
- Minimumweight: Up to 46kg
- Light Flyweight: 46–49kg
- Flyweight: 49–52kg
- Bantamweight: 52–56kg
- Featherweight: 56–60kg
- Lightweight: 60–64kg
- Light Welterweight: 64–69kg
- Welterweight: 69–75kg
- Middleweight: 75–81kg
- Light Heavyweight: 81–92kg
- Heavyweight: 92kg+

Weight Cutting
Some athletes "cut weight" — dehydrating and dieting to make a lower weight class, then rehydrating before competition. This practice is controversial and carries health risks. Australian amateur boxing bodies require weigh-ins close to competition time to reduce extreme weight cutting. Beginners should compete at their natural walking weight.
Masters/Veteran Categories
Masters boxing (for athletes over 35) uses the same weight classes but with modified rules including mandatory standing eight counts and additional safety considerations.
