<P> Different positions require different passing skills . The fake pass should be mastered by every position . The centre pass should be mastered by the Centre . The Centre should also master any pass that must be made on the run . Both the Goal Attack and Wing Attack should be familiar with the long passes and the lob and drop pass . The Goal Attack should also be familiar with all styles of passing . The Goal Shooter should know how to do penalty passes . The Wing Defence should also be comfortable making lob passes . The Goal Defence should know how to make goal - line passes . The Goal Keeper should be comfortable making penalty passes and inbounding the ball . </P> <P> Contact is only permitted provided it does not impede with an opponent or the general play and players must be at least 0.9 metres (3 ft) away from a player with the ball while attempting to defend . If impeding contact is made, a penalty is given to the team of the player who was contacted, and the player who contacted must stand "out of play", meaning they cannot participate in play until the player taking the penalty has passed the ball . </P> <P> Only the Goal Attack and Goal Shooter are able to score goals directly, and this may only be done from the inside of the semicircle . The job of the Goal Defence and Goal Keeper is to block the Goal Attack and Goal Shooter from shooting; however, they must be three feet or more away from the landing foot of the shooter, otherwise it is called an obstruction . In this penalty situation, the Goal Keeper or Goal Defence must stand by the shooter's side for a penalty pass or shot, and must remain out of play until the ball is thrown . A ball that passes through the hoop, but has been thrown either from outside the circle or by a player other than the two shooters, is deemed a "no goal". Furthermore, a shooter (GA or GS) may not shoot for a goal if a "free pass" has been awarded for an infringement such as stepping, offside, or using the post . </P> <P> If a player completely misses a shot, the player may not catch it; if she does, it is called a "replay", and a free pass is awarded to the other team . If the ball is deflected off the goal keeper or goal defence and goes through the goal ring, it is a no goal and play continues . </P>
