One of the most common arguments used to justify the installation of synthetic sports fields is that they provide significantly greater playing capacity than natural turf.
At first glance, this sounds logical. Synthetic fields can be used in wet weather, require less recovery time between matches and can generally withstand heavier use than poorly maintained natural grass fields.
However, the capacity debate is often oversimplified.
The real question is not whether synthetic turf can be used for more hours. The question is whether communities are accurately measuring sporting capacity and whether synthetic turf is the most appropriate and cost-effective way to meet demand.
The Problem with Measuring Capacity by Hours
Many council reports compare natural and synthetic fields based on the number of hours each can be booked.
A typical comparison might suggest:
- Natural turf: 30–40 hours per week
- Synthetic turf: 60–70 hours per week
This comparison immediately creates the impression that synthetic turf offers twice the capacity of natural grass.
The problem is that these figures often compare a poorly maintained natural field with a synthetic field operating under ideal conditions. It is not an “apples with apples” comparison. Independent sports turf experts have repeatedly pointed out that well-designed and properly maintained natural turf fields can accommodate substantially more use than many council reports suggest.
Best Practice Natural Turf Can Deliver Much More
Sports turf consultant Mick Battam of AgEnviro has argued that many capacity assessments underestimate the performance of modern natural turf systems.
Through improved drainage, irrigation, turf selection and maintenance practices, natural fields can often support between 45 and 50 hours of organised sport per week while maintaining acceptable playing conditions. This is significantly higher than the 30 hour figure commonly quoted in planning documents.
The implication is important. If a community’s demand is 45 or 50 hours per week, a well-designed natural turf field will be capable of meeting that demand without the need for a synthetic conversion.
Booked Hours Are Not the Same as Actual Use
Another challenge is that many capacity studies rely on booking data rather than actual field utilisation. Just because a sporting club books a field does not mean it is being actively used for the entire booking period.
Many councils allocate large blocks of time to clubs months in advance. These bookings may not reflect actual attendance, player numbers or field occupancy. As a result, booking schedules can overstate demand.
Communities deserve transparency regarding:
- Actual field utilisation
- Peak demand periods
- Seasonal demand patterns
- Number of participants using the facility
- Type of participants using the facility and their ‘wear’ factor
- Unused or cancelled bookings
Without this information it becomes difficult to determine whether additional capacity is genuinely required.
Carrying Capacity Matters More Than Hours
Perhaps the most important issue is that sporting capacity should not be measured solely in hours. Capacity is ultimately about how many participants can be accommodated. A field used by 30 players for two hours is very different from a field used by 200 players over the same period.
Sportsfield experts recommend measuring “carrying capacity” rather than simply counting booked hours.
Carrying capacity considers:
- Number of participants
- Type of sport
- Seasonal use
- Field condition
- Recovery requirements
- Maintenance practices
This approach provides a far more meaningful measure of community benefit.
The Hidden Assumption in Many Synthetic Turf Proposals
Many synthetic turf business cases assume that if a field can theoretically accommodate 70 hours per week, those hours will actually be used. In practice, this assumption is often questionable.
Many synthetic fields never achieve their theoretical capacity. Demand may be concentrated on weekday afternoons and weekends, leaving significant periods of unused availability. A field capable of accommodating 70 hours per week but only used for 45 hours does not provide any practical capacity advantage over a natural field capable of supporting similar demand.
This raises an important question for decision-makers: Are communities paying millions of dollars for capacity that may never be needed?
Capacity Must Be Balanced Against Other Factors
Capacity is only one factor in the decision-making process.
Councils must also consider:
- Capital costs
- Whole-of-life costs
- Environmental impacts
- Urban heat effects
- Microplastic pollution
- PFAS concerns
- Community preferences
- Biodiversity outcomes
- End-of-life disposal costs
A field that provides additional theoretical capacity may not necessarily provide the best overall outcome for the community.
Asking Better Questions
Before approving a synthetic turf project, councils should be able to answer several fundamental questions:
- What is the actual demand for field use?
- How much of the existing booked time is genuinely utilised?
- What capacity could be achieved through best-practice natural turf management?
- Has carrying capacity been assessed rather than simply booked hours?
- Is the additional synthetic capacity likely to be used?
- Have all costs and environmental impacts been fully considered?
- Is it important that the field is available for broad community use?
These questions are essential if communities are to make informed decisions.
Conclusion
The natural versus synthetic turf debate is often framed as a simple capacity issue. In reality, the situation is much more complex.
Well-managed natural turf can provide substantially greater capacity than many reports suggest. Capacity should be measured by actual participation and carrying capacity rather than theoretical booking hours alone. Most importantly, councils should demonstrate that any additional capacity provided by synthetic turf is genuinely required before committing millions of dollars to these projects.
The goal should not be to maximise theoretical hours of use. The goal should be to provide the greatest overall benefit to the community while balancing sporting needs, environmental impacts and long-term financial sustainability.
