What Is 'Over a Third' in Netball?
The over a third rule in netball explained: why the ball can't be thrown over a full third of the court without being touched.
The ball can't be thrown directly over a full third of the court — from behind one transverse line to beyond the next — without being touched or caught by a player standing in the third it crosses.

Over a third is a rule most players rarely think about, but it's a deliberate limit on how far the ball can be thrown in a single pass.
The rule in plain English
A player cannot throw the ball so that it crosses an entire third of the court without touching or being caught by a player standing in that third. In practice, this means a pass thrown from within the defensive third can't sail directly over the whole centre third and land in the attacking third — someone has to touch or catch it while it's still within the centre third.
A simple example
A Goal Keeper, deep in the defensive third, throws a long, high pass that travels the entire length of the centre third and is caught directly by a Goal Attack already standing in the attacking third. Because no player touched the ball while it was over the centre third, this is over a third.
Legal vs illegal
| Legal | Illegal |
|---|---|
| A long pass within two adjoining thirds (e.g. defensive to centre third) | A pass thrown from one third directly into the third beyond the next, with nobody touching it in between |
| A pass that crosses a full third but is touched by a player standing in that third | A pass that clears an entire third with no contact by any player in it |
What the umpire is looking for
The umpire is tracking the ball's flight relative to the transverse lines, watching whether any player makes genuine contact with it while it's within the third it's crossing.
Restart
Over a third is restarted with a free pass, taken from the spot where the ball crossed the second transverse line.
Common misunderstandings
- "Any long pass is illegal." A long pass is completely legal as long as it doesn't clear a full third untouched — most long passes stay within two adjoining thirds and are unaffected by this rule.
- Confusing this with over-the-line rules in other sports. This isn't about a single line, but about clearing an entire third's width without contact.
Player tips
- When passing from deep in your own third, know roughly how far a full-third pass would need to travel, and aim to keep it within two thirds unless you're confident a teammate can touch it in the middle third.
Umpire tips
- Track the transverse lines specifically during long passes, since this infringement is easy to miss at speed if attention is only on the receiver.
Related rules
Over a third and short pass are the two ball-control rules most players encounter least often, both designed to keep passing genuinely contestable rather than allowing the ball to skip large areas of the court untouched.
Common mistakes
- A long pass from deep in the defensive third landing directly in the attacking third without anyone touching it in the centre third.
- Misjudging where the transverse lines actually are during a fast passage of play.
- Confusing this with a simple long pass within two thirds, which is completely legal.
