1.4.14 Netball
Netball is a team game based on running, jumping, throwing and catching. Teams may include up to 12
players but only 7 may take to the court at any one time.
The aim of the game is to score as many goals as possible by throwing a ball through a hoop situated
on top of a post. The game is played on a hard court.
The court
The court is 30.5 metres long and 15.25 metres wide and is divided into thirds. There is a centre circle
with a diameter of 900 mm and two goal circles which are semi-circles measuring 4.9 metres in radius.
All lines are part of the court and measure 50 mm in width.
The goal posts are placed mid-point on each goal line and measure 3.05 metre in height. The goal
rings have an internal diameter of 380 mm. The goal rings project horizontally from the post on a single
attachment measuring 150 mm.
The ball
The ball is made of leather, rubber or similar material, weighing 400 – 450 grams and has a circumference
of 690 – 710 mm.
Construction of court
The courts have a hard surface and may have an ashphalt or an artifi cial synthetic surface. The substrate
preparation is the same for both types of surfaces.
Artifi cial synthetic surfaces on concrete substrates
The surface preparation for artifi cial playing surfaces may be briefl y described as follows:
• The sub-surface earth needs to be levelled and compacted to 95 % Modifi ed ASSHTO with
a maximum cross slope of 1%.
• Sub-Surface drainage system to be installed below all fi eld surfaces (in terms with Civil
Engineering design). Install sub-surface drainage comprising 110 mm diameter agricultural
drains placed in 450 x 600 mm deep herring bone drainage system at 6 metre intervals and
to entire perimeter of the cricket fi eld.
• Sub-surface drains to be lined with a “Bidum” Hessian layer and fi lled in with 19 mm
crusher run stone.
• Sub-Surface drains to connect at the lowest point to a storm water catch pit which should
be connected to a storm water main.
• The sub-surface drains are then covered with a 100 mm thick layer of crusher run to assist
in the sub-surface drainage.
