How many security guards do you need for an event?
There is no single ratio that answers this for every event. There are legal minimums for certain categories, and beyond those the number comes from the shape of your event. Here is how we work it out.
Queensland has no blanket guard-to-guest ratio for events. Set minimums apply to specific categories: a high-risk event needs 7 crowd controllers for the first 1,000 patrons plus 1 more for every 250 after that, and an approved all-ages or under-age event starts at 2 for up to 200 patrons. Outside those categories the number comes from your entry points, liquor arrangements, finish time and crowd, rather than headcount alone.
Start from the legal floor
Before working out what your event needs, check whether a minimum already applies. Three sets of numbers cover most Queensland events.
High-risk events (Guideline 33)
The Office of Liquor and Gaming Regulation sets a minimum for events it classes as high risk: 7 crowd controllers for the first 1,000 patrons or part thereof, then at least 1 more for every 250 patrons or part after that. A minimum of 2 of them have to keep watch outside the event area for an hour after it finishes, or until everyone has cleared the vicinity.
Factors that push an event into that category include liquor trading for more than five hours, trading before 10am or after midnight, expected attendance above 2,000 a day, more than half of patrons drinking, a licensed area over 2,000 square metres, all-ages entry, and a concert or festival format.
Under-age and all-ages events (Guideline 11)
Approved under-age and all-ages events have their own scale, and the crowd controllers must be licensed under the Security Providers Act 1993 and present for the whole event:
- Up to 200 patrons or part thereof: 2 crowd controllers
- 201 to 300 patrons: 3 crowd controllers
- 301 to 400 patrons: 4 crowd controllers
- 401 to 500 patrons: 5 crowd controllers
- Above 500: at least 1 more for every 250 patrons or part thereafter
Licensed venues
If you are hiring a licensed venue, its conditions apply on top of anything your event triggers. Inside the Brisbane City Council area, venues trading past 1am work to a set scale under the Liquor Regulation 2002: 1 crowd controller for up to 100 patrons, rising by 1 for each additional 100 up to 500, then 1 more for every 250 above that. They are required from 11pm on those nights and for at least an hour after close, and the condition drops away on nights the venue shuts by 1am. Outside the council area, the venue's own licence conditions set the requirement, so ask the manager for theirs in writing.

What actually moves the number
A minimum is a starting point. Two events with 300 guests each can need very different teams, and these factors change our answer most often.
- Entry points. Every door that opens needs someone on it. A hall with one controlled entry is a different job from a park activation with four gates.
- Liquor. Alcohol adds door assessments, refusal-of-service conversations and a livelier finish.
- Finish time. Events ending after midnight need more cover at the end than at the start, because egress is when incidents cluster.
- Layout and sightlines. Multiple rooms, marquees and outdoor overflow all cost coverage.
- Crowd profile. A seated awards dinner behaves differently from a standing music event of the same size.
- What else is on site. Cash bars, gifted product and AV loads need someone accountable for them.
- Distance from help. A semi-rural site with a longer police response needs a team that can hold a situation on its own for longer.
If any of these shift after you book, tell your provider as soon as you know.
Count posts, then count people
Start with posts: the fixed jobs that have to be covered from the moment doors open to the moment the last guest leaves. Once the posts are listed, the headcount falls out of it. A typical list looks like this:
- Entry and screening. ID checks, ticket or list verification, intoxication assessment, bag checks if you run them.
- Floor or crowd. Roaming presence through the main space, dealing with issues early.
- Bar or service line. Where alcohol is served, particularly at peak.
- Back of house. Storage, staff areas, load dock, the green room, anything a guest should not walk into.
- Carpark and egress. Arrival flow early, dispersal and rideshare marshalling at the end.
- Supervisor. Above a handful of officers, one person untied to a post who can move to whatever is happening and be your single point of contact.
Entry is heaviest for the first hour and egress for the last, so a good plan moves people between posts as the night shifts. That is how you get proper cover without paying for a team sized to every peak at once.
Three worked examples
Illustrations of the scoping, not quotes and not legal minimums.
150-guest corporate function at a licensed venue
One entry, seated dinner, bar service, finishing by 11pm. The venue's licence conditions carry most of the obligation, and the usual shape is a small team on the door and the room with venue staff covering back of house. Our Brisbane corporate function checklist covers how this one runs on the night.
400-guest all-ages community event
Guideline 11 sets the floor at 4 crowd controllers. Layout usually pushes it higher, because an all-ages event tends to have a perimeter to hold and a pick-up zone to manage at the end.
1,200-guest ticketed music event
Attendance, format and a late finish will usually put this into the high-risk category, so the floor is 7 crowd controllers for the first 1,000 and 1 more for the remaining 200, with 2 staying an hour past the finish. A plan at this size also needs a supervisor, stage and back-of-house cover, and a briefed egress team.
Common sizing mistakes
- Booking to the legal minimum and stopping there. The minimum is a compliance number. It says nothing about how your site behaves at 11pm.
- Forgetting the finish. Plenty of events are well covered at the door and thin at the exit.
- No supervisor. Past about six officers, someone has to run them, or you do it yourself.
- Assuming venue staff count. Bar and floor staff are not licensed crowd controllers and cannot fill that requirement.
FAQ
Is there a legal guard-to-guest ratio in Queensland?
There is no single ratio that applies to every event. Set minimums apply to particular categories. A high-risk event under OLGR Guideline 33 requires 7 crowd controllers for the first 1,000 patrons or part thereof, then at least 1 more for every 250 patrons or part thereafter. An approved under-age or all-ages event under Guideline 11 starts at 2 crowd controllers for up to 200 patrons and rises to 5 at 500, then adds 1 for every 250 after that. Licensed venues carry their own conditions. Outside those categories the number comes from a risk assessment of your event.
Do I need more security if my event serves alcohol?
Usually yes. A liquor licence or a one-off permit normally carries crowd controller conditions, and liquor service is one of the factors OLGR weighs when classing an event as high risk, along with a session running more than five hours, finishing after midnight, or more than half of patrons drinking. On the ground, alcohol adds refusal-of-service conversations, intoxication assessments at the door and a busier finish, so the team usually needs more people on the bar line and on egress than a dry event of the same size.
How we scope it
We size an event off a site visit and a short brief. We walk the entries, the bar positions, the back-of-house doors and the exit route, then write a post plan that separates the legal minimum from our judgement. Our event security and static guard teams work across Brisbane CBD and Ipswich.
None of this is legal advice. Your liquor licence, permit and venue conditions are the authority for your event, and OLGR or your venue can confirm what applies.
