Goal Defence (GD) in Netball
Goal Defence (GD) in netball explained: permitted court areas, key skills, common mistakes and how it compares to Goal Keeper.
Goal Defence is one of netball's most physically and tactically demanding positions, combining mid-court marking with circle defence at the highest level of pressure.
Where GD can go
GD covers the defensive third, centre third and defensive goal circle. Like Goal Attack on the other end, GD is a two-third-plus-circle position, giving it more range than either Wing Defence or Goal Keeper individually.
Defensive role
GD's primary job is marking the opposing Goal Attack, following them from the centre third into the circle and working to prevent clean feeds and shots. Alongside Goal Keeper, GD forms the last line of defence around the circle.
Key skills
- Marking across two thirds, adjusting defensive intensity as play moves from mid-court into the circle.
- Circle defence — contesting shots and rebounds alongside Goal Keeper without conceding contact or obstruction.
- Interception, particularly on feeds into the circle from Wing Attack or Centre.
- Communication with Goal Keeper to avoid both defenders committing to the same attacker and leaving space open.
Drills and tactics
GD is central to circle defence and interception drills, and works as a unit with Goal Keeper in most zone defence structures.
GD vs GA — the direct opponent
GD marks the opposing Goal Attack directly. This is one of netball's most demanding match-ups, since both positions operate across the centre third and a goal circle, combining speed, strength and decision-making.
GD vs GK
GD and Goal Keeper both defend the circle, but GD also covers the centre third while GK is restricted to the defensive third and circle only. See Goal Keeper for the comparison.
Beginner tips
- Practise transitioning your defensive intensity as play moves from the centre third into the circle — the two require slightly different positioning.
- Work with your Goal Keeper on a simple, consistent system for who takes the shooter and who covers space, rather than reacting individually each time.
- Focus on footwork and body position over reaching — over-committing to intercept is one of the fastest ways to lose your marking position.
Common mistakes
- Ball-watching in the circle instead of tracking Goal Attack's movement off the ball.
- Overcommitting to intercept and losing defensive position as a result.
- Stepping into the attacking third or attacking circle, which GD is never permitted to enter.
