Netball Court Line Marking

Netball Australia specifies 30.5m long by 15.25m wide for senior courts, measured on the outside edge of boundary lines. Goal circles must be 4.9m radius (measured from goal post centre), not 5.0m or "about 5 metres". Centre circle must be 0.9m radius positioned at exact court centre. Transverse lines dividing the court into thirds must be positioned at 10.167m from each goal line (30.5m divided by 3). Goal lines are positioned 0.15m behind each goal post. Line width should be 50mm throughout. Many school courts marked decades ago are slightly off these dimensions because measurements were done with tape measures instead of laser equipment. If you're applying for competition hosting or Netball Australia affiliation, dimensions must be exact. We verify measurements before quoting and tell you honestly if existing court needs adjustment.

We use weighted string compass systems anchored at exact goal post centres. The process: establish goal post positions using laser measurements (must be exactly 0.15m inside goal lines, centred on court width), drive anchor pin at ground level at post centre, attach 4.9m string with weighted marking guide, rotate the guide 360 degrees while maintaining tension to scribe perfect circle. This creates mathematically accurate circles, not the egg-shaped ovals you get from freehand attempts. We mark pilot circles in chalk first so you can verify they're perfect before we commit to paint. A netball club in Heidelberg had existing goal circles that were obviously oval-shaped. Measuring revealed they were 5.2m in one direction, 4.7m in the other direction. We remarked them properly using string compass method. Players immediately noticed improved game play because shooting positions were consistent all around the circle.

Yes, this is extremely common in schools and community facilities where space is limited. We mark netball lines in a contrasting colour so both sports can use the same surface. Typical combinations: white tennis lines with red or yellow netball lines, white basketball lines with red netball lines. The challenge is positioning netball courts to minimize conflicts with existing lines. Sometimes we can orient the netball court differently to reduce line confusion. A primary school in Coburg North had tennis courts they wanted to convert to multi-sport. We marked full regulation netball courts in red over the existing white tennis lines. Students can play both sports on the same surface without confusion because colour differentiation makes it obvious which lines apply to which game.

Goal circles and centre court experience significantly more wear than boundary lines or transverse lines because of pivot movements. Netball rules require players to plant one foot and pivot on it, creating rotational friction that wears paint faster than running or walking. Goal shooters and goal keepers spend entire games pivoting in the goal circles. Centre players pivot repeatedly at centre court. These areas might need repainting every 2-3 years while boundary lines last 5-6 years. We use reinforced acrylic paint systems with higher solids content and additional UV stabilizers in these high-wear zones. Some clubs ask us to apply three coats in goal circles and centre court versus two coats elsewhere for extended durability.

Yes. Netball Australia specifies modified court dimensions for younger age groups: NetSetGO courts for 5-10 year olds (smaller dimensions, 9m x 4.5m for youngest groups), modified courts for 11-12 year olds (shorter lengths but similar width), full regulation courts for 13+ and adults. Many schools and clubs want multiple court sizes marked on the same surface to accommodate different programs. We can mark these using different colours or partial line systems. A netball club in Frankston has full regulation courts with modified junior courts marked inside them in different colours. This lets them run junior programs and senior competitions on the same facility without constantly remarking for different age groups.

Depends entirely on usage intensity, climate exposure, and surface condition. School courts with moderate use (PE classes, after-school training) marked with quality acrylic systems last 4-6 years for boundary lines and transverse lines, 2-4 years for goal circles and centre court where pivot wear occurs. Competition courts with intense daily training and weekly games might need high-wear zones touched up every 18-24 months. Courts exposed to harsh UV (northern Australia, unshaded positions) fade faster than shaded courts. Surface condition matters too. Courts on poorly maintained asphalt with cracking deteriorate faster than courts on well-maintained surfaces. A community centre in Braybrook had us mark courts in 2018 using premium acrylic systems. Five years later the boundary lines still look excellent. Goal circles needed one refresh in 2021 because of heavy training use. They're now considering just repainting goal circles and centre sections rather than entire courts, saving roughly 60% of remarking costs.
