Feeding 10,000 or more people at an event is not a catering problem. It is a capacity, layout and compliance problem, and events that fail do so for the same handful of reasons every time — almost never because the food was bad.
The core discipline: plan against peak demand, not average demand, and design the site so vendors do not compete for the same queue space.
Key takeaways
- Plan roughly one vendor per 400–600 attendees for a full-day event.
- Peak demand is 2–3× the hourly average — planning against the average guarantees failure.
- Precinct layout matters as much as vendor count; clustered trucks share one queue.
- The organiser is generally responsible for ensuring vendor compliance, not each vendor alone.
- Above about ten vendors, a single coordinator outperforms direct contracting.
Capacity planning#
| Attendance | Vendors (full day) | Peak-hour covers needed |
|---|---|---|
| 2,000 | 4 – 6 | 400 – 700 |
| 5,000 | 9 – 13 | 1,000 – 1,700 |
| 10,000 | 17 – 25 | 2,000 – 3,500 |
| 25,000 | 40 – 60 | 5,000 – 8,500 |
| 50,000+ | Precinct model | Modelled per site |
The method, in four steps:
- Estimate what share of attendees will eat on site. Dwell time drives this. A six-hour festival is close to 70–80%; a two-hour community event may be 30%.
- Identify the peak hour. Usually the main dinner period or the changeover before a headline act.
- Assume peak is 2–3× the hourly average.
- Divide peak-hour demand by realistic vendor throughput of 80–120 covers per hour.
Most under-capacity failures come from skipping step 3.
Precinct design#
Vendor count is only half the answer. Where they stand determines whether you actually get the capacity you paid for.
Separate vendors properly. Two trucks side by side generate one queue that people join at the nearest end. Twenty to thirty metres apart generates two genuinely independent queues.
Build precincts, not a row. At scale, several distributed food areas beat one long line of vendors. A single strip concentrates the entire site's demand into one corridor.
Face queues into open space, not across circulation routes. A queue across a thoroughfare blocks the site and makes it feel more crowded than it is.
Separate ordering from collection. People waiting for food should not be standing in the line for people ordering.
Distribute cuisines across precincts. If every burger vendor is in one area, that area fails while another sits quiet.
Put amenities and bins deliberately. Food, water, toilets and waste all cluster demand. Spread them.
Tip
The cheapest capacity increase at a large event is almost never another vendor. It is shorter menus, better signage and separating trucks that were placed too close together. All three are free and all three are routinely overlooked.
Vendor mix#
Cuisine spread over duplication. Attendees self-distribute across different offers, which shortens every queue. Six similar vendors compete for one queue; six different ones create six.
A genuine value option. Every large event needs a visible affordable choice. Without one you create both a perception problem and a demand spike at whichever vendor happens to be cheapest.
Dietary coverage as baseline. Vegetarian throughout, with credible vegan, gluten-free and halal options. At this scale that is a service obligation, not a preference.
Throughput-weighted selection. A vendor serving 120 an hour contributes more to site capacity than one serving 60, regardless of how good the food is. Ask for realistic hourly rates during selection.
Desserts and coffee. These trade outside the main peak and smooth the overall curve.
Compliance at scale#
This is where the administrative weight sits, and where organisers carry genuine responsibility.
Each vendor holds their own food business registration under the relevant state Food Act, administered by councils — Victoria through Streatrader with a Statement of Trade, New South Wales under the Food Act 2003 with the NSW Food Authority, and equivalent arrangements in other states.
But the event needs its own approvals, and the organiser is generally responsible for ensuring every vendor on site is compliant.
What you collect from each vendor:
- Current food business registration for the jurisdiction.
- Certificate of currency for public liability, commonly $10M or $20M.
- Gas and electrical compliance evidence where required.
- Site requirements: dimensions, power draw, water, waste.
- An on-day contact who is not the person cooking.
Check with your council
Rules, permits and fees are set by individual councils and change regularly. Confirm current requirements with the council where you’ll be trading before you commit money.
Event approvals, permits and fees are set by the council hosting the event and change regularly. Lead times for large events on public land frequently run to several months and can exceed vendor booking timelines. Start the approval process before you start contracting vendors.
The failures that recur#
Having run food operations at the Melbourne Cup carnival at Flemington as contractor to Crown Resorts and the VRC across 300,000+ attendees, the Australian Open across the Grand Slam Oval, Western Courts, Ballpark and Middle Terrace precincts, the Melbourne International Flower and Garden Show as exclusive hospitality partner with the City of Melbourne and IMG across 200,000+ attendees, and a decade of Melbourne New Year's Eve, the same failures appear at every scale:
- Planning against average demand instead of peak.
- Clustering vendors so separate queues merge into one.
- Menus designed to impress rather than to serve at volume.
- Collecting compliance too late, producing a scramble in the final week.
- No contingency for a vendor withdrawing or failing on the day.
- Under-resourcing waste, which is what attendees photograph.
None of these are food problems. All are planning problems, and all are solvable weeks in advance.
Technology at scale#
Above roughly 5,000 attendees, ordering capacity rather than cooking capacity becomes the binding constraint. Preordering and self-service kiosks add ordering points without adding staff, which is the cheapest real capacity available — covered in cutting food queues at events.
