Know Who's Behind Your 40th Birthday Party

It's not just about what's on offer for your 40th Birthday Party – it's about who's behind it.

The Sydney 40th Birthday Planning Checklist

A 40th in Sydney is often the biggest birthday since the 21st – friend groups have grown across work, family and years of different social circles, and there's usually a bigger budget behind it too. Function rooms, private dining and boat charters for 40–80 guests are the most common formats.

Expect catered set-menu packages from $65–$110 a head depending on the venue and drinks inclusions
Entertainment (a band, DJ or photo booth) is usually booked as a separate line item on top
Compare whether the venue can handle a mixed-age guest list comfortably (seating, noise levels, accessibility for older relatives)
Check what AV or entertainment set-up is already on-site
Ask whether Saturday-night pricing carries a premium over other nights

Enquire with a few Sydney suppliers directly through Party Hero to compare pricing, availability and inclusions for your date – there's no booking fee or markup, so the price you're quoted is the price you pay.

A private function room or restaurant space – the most common format, usually booked exclusively for the night rather than shared with other diners
A boat charter – a half-day or evening cruise around the harbour, popular when the guest list includes people who don't see each other often
A backyard or marquee celebration – hiring in caterers, a marquee and styling rather than booking a venue, common for a milestone birthday with a larger family-and-friends guest list
A weekend away – a smaller group booking accommodation together rather than a single-night event

What a 40th Typically Costs, Broken Down

Venue-based catering runs $65 to $110 a head as noted above, with the top of that range usually including a drinks package rather than food alone
A backyard or marquee celebration shifts the cost from a per-head venue package to separate line items – marquee or furniture hire, catering, and any styling or florals – which can come in cheaper for a very large guest list but takes more coordinating
Entertainment is rarely bundled into a venue package – budget it as its own line item on top of catering
A speech-and-slideshow format costs nothing extra beyond a microphone, but ask early whether the venue has one built in

Before You Book: 40th Birthday Party FAQs

Is entertainment included in the venue package, or booked separately?

Usually separate – a band, DJ or photo booth is typically quoted as its own line item on top of the venue and catering package.

Will the venue suit a guest list with a wide age range?

Worth checking directly – a 40th often spans a wider age range than a younger birthday, so ask about seating, noise levels and accessibility for older relatives before booking.

Does the venue already have AV or entertainment equipment on-site?

Ask this upfront – some venues have a sound system or AV setup ready to go, which can save booking additional equipment separately.

Does a Saturday night booking cost more than other nights?

Often yes – ask the venue directly whether Saturday-night bookings carry a premium over other nights of the week.

What's actually covered in a set-menu package?

This varies by venue – confirm exactly what's included in the drinks package and whether the menu is fixed or flexible, since it affects the final per-head price.

Should we book a videographer to capture speeches?

It's worth considering – many groups bring in a videographer separately to capture speeches, especially from guests who've travelled specifically for the occasion.

How many guests does a typical 40th cater for?

Function rooms, private dining spaces and boat charters for 40 to 80 guests are the most common format, reflecting the wider friendship and family circles built up over 20 years.

Is a backyard or marquee celebration usually cheaper than booking a venue?

It can be, especially for a large guest list, since you're paying for marquee hire, catering and styling separately rather than a bundled per-head venue package – but it takes more coordinating between suppliers than a single venue booking.

Do we need a microphone for speeches, or does the venue provide one?

Not every venue has one set up by default, so if speeches or a slideshow are part of the night, confirm with the venue directly rather than assuming.
