How to Cater a Corporate Event for 100+ Guests in Sydney

Serving 30 people at a corporate lunch is straightforward. Serving 120 at a cocktail party or 200 at a gala dinner is another story. With larger groups:

• Queues multiply quickly if there are not enough bars or buffet lines
• Food can run out fast if quantities are not carefully planned
• Dietary requirements scale up, and you may be managing dozens rather than just a handful
• Service flow becomes critical, and the right staff-to-guest ratio makes or breaks the event

Different catering formats suit different kinds of corporate events:

• Plated Dinner – Formal and structured, ideal for awards nights or client-facing galas. Works well up to about 150 guests with strong staffing.
• Buffet – Efficient and cost-effective. Needs multiple buffet lines to avoid long queues.
• Food Stations – Adds variety and breaks up crowds. Examples include a seafood station, charcuterie station or hot carvery.
• Cocktail and Grazing – High energy and ideal for networking. Roving canapés with a central grazing table keep people moving and talking.

At this scale, precise calculations prevent the embarrassment of running out of food.

• Cocktail style: 10–12 canapés per guest, plus 1–2 substantial bites
• Buffet style: 1.5 servings per guest for popular items, to cover second helpings
• Plated dinners: 3–4 courses, planned to flow with speeches or presentations
• Dessert: Bite-sized portions are ideal for networking functions

With 100 people, you will often have dozens of dietary requests. The key is to plan inclusively without slowing service.

• Collect dietary needs early in RSVPs
• Offer at least one vegetarian or vegan option that feels like a hero dish
• Pre-plate special meals (gluten-free, halal, vegan) and label them clearly

Drinks service is often where large events stumble. Long queues at the bar can derail the mood.

• Bar formats: Choose between a full open bar, a streamlined menu with beer, wine, soft drinks and one cocktail, or curated pairings for plated dinners
• Bartender ratios: One bartender per 40 guests for basic drinks. For cocktails, plan one per 30
• Drinks per person: Budget two drinks per guest per hour
• Glassware and ice: Always over-order. Allow 1.5 glasses per guest per hour, and 1kg of ice per guest
• Licensing: At non-restaurant venues, you may need a caterer licensed to serve alcohol

The right number of staff ensures smooth flow.

• Plated dinner: 1 waiter per 10–15 guests
• Cocktail style: 1 waiter per 20 guests
• Bartenders: 1 per 30–40 guests depending on drinks offered
• Supervisor: For 100+ guests, an event supervisor is essential to coordinate

These are the overlooked details that often cause stress:

• Multiple service points, such as at least two buffet lines or bars for 100+ guests
• Back-of-house space, which can be created from a garage or side room to serve as a catering station
• Deliveries and access, including loading docks, lifts and parking for vans
• Waste management, as 100+ people generate more waste than expected
