One of the most common questions we get before a booking is: “What size bus do we actually need?” It sounds simple, but get it wrong and you’re either squeezing people in or paying for seats that sit empty. This guide walks you through how to match your group size to the right vehicle — and flags a few things beyond headcount that are worth thinking about.
The quick answer: size by headcount
Here’s a straightforward starting point based on group size alone:
| Group Size | Vehicle Type | Notes |
|---|---|---|
| Up to 12 | Minivan or small minibus | Good for airport transfers, small corporate groups |
| 13–24 | Standard minibus | Versatile, easier to park in tight locations |
| 25–27 | Large minibus | Popular for weddings, wine tours, and day trips |
| 28–53 | Standard coach | More cost-effective per seat, better for longer trips |
| 54–57 | Large coach | Best for bigger groups wanting a single vehicle |
| 58+ | Multiple vehicles | We’ll help you work out the right combination |
That said, headcount is just the starting point. Keep reading — there are a few other factors that can shift the recommendation.
Minibus vs coach: what’s the real difference?
The main tradeoff between a minibus and a coach isn’t just size — it’s a combination of capacity, cost, and practicality.
| Minibus | Coach | |
|---|---|---|
| Typical capacity | Up to 24 (standard) or 27 (large) | Up to 53 (standard) or 57 (large) |
| Maneuverability | Better in tight spaces, laneways, venue access roads | Needs more room — worth checking venue access |
| Cost per seat | Higher | Lower — more efficient for bigger groups |
| Luggage space | Limited | Large underfloor storage bays |
| Comfort on long trips | Fine for under 2 hours | Better for longer distances |
One thing that surprises people: once your group exceeds 27 passengers, a single coach is almost always cheaper than running two minibuses. Two drivers, two vehicle hire fees, and twice the coordination — it adds up fast. If you’re sitting at 28–35 people, a coach is likely your best move even if it feels like overkill on paper.
Size by event type
Group size matters, but so does the type of event. Here’s how we typically think about it:
Weddings
For weddings, we exclusively use Premium or Luxury vehicles — presentation matters, and Economy isn’t an option for these bookings. The right size depends on whether you’re moving the wedding party, all guests, or both:
- Bridal party only — a smaller minibus is usually perfect
- Guest shuttle (up to 24) — standard minibus, one run or multiple loops
- Guest shuttle (25–27) — large minibus, still nimble enough for most venues
- Guest shuttle (28+) — a coach simplifies logistics and reduces cost
- Multiple pickup points — we can run a coach on a circuit or use two vehicles depending on timing

Corporate events and conferences
Corporate bookings often involve multiple pickup locations (hotels, offices) and tight timing. A coach works well for larger groups heading to a single venue; for VIP transfers or smaller executive groups, a minibus is more appropriate. If you have attendees spread across multiple suburbs, we can advise on whether one vehicle doing loops or multiple vehicles running simultaneously makes more sense.
Wine tours and day trips
For Yarra Valley, Mornington Peninsula, or Great Ocean Road day trips, comfort over distance matters more than it does for short transfers. Coaches offer more legroom and underfloor storage for bags. That said, some winery access roads and smaller venues are easier to reach in a minibus — worth flagging your itinerary when you enquire so we can advise on what fits best.
School excursions
School groups typically need seatbelted vehicles, which affects which buses are available. We’ll always confirm seatbelt availability for school bookings — just let us know it’s a requirement when you enquire. For larger school groups, a coach is usually the most practical option.
Sports groups and social events
Footy trips, bucks weekends, race days — these bookings tend to be straightforward on size but worth confirming luggage needs. Sports groups carrying bags and equipment often need more storage than a minibus can offer, making a coach the better fit even at lower passenger numbers.
Other things that affect the decision
Venue access
Some Melbourne venues — particularly in the Yarra Valley, on the Mornington Peninsula, or in inner-city laneways — have restricted access for large vehicles. If you’re unsure whether a coach can get in, mention the venue when you enquire and we’ll advise. It can be the deciding factor between a minibus and a coach even when the headcount would normally point to a larger vehicle.
Luggage and equipment
Coaches have large underfloor storage bays. Minibuses have limited luggage space. If your group is carrying overnight bags, sports gear, or anything bulky, factor that in — sometimes it pushes you up to a coach sooner than the headcount alone would suggest.
Trip duration
For anything over two hours on the road, a coach is generally more comfortable — better seats, more legroom, and on some vehicles, onboard toilet facilities. For short transfers across town, a minibus is perfectly comfortable and easier to work with in traffic.
Budget
If you’re flexible on vehicle size, sometimes going slightly larger is actually cheaper. As mentioned above, once your numbers hit 28+, a coach consistently undercuts the cost of two minibuses. Our pricing guide has more detail on how the numbers typically break down.
