Coast Port Beach is a beachfront function venue sitting in the sand dunes of North Fremantle, five minutes from Fremantle Markets and Cottesloe and a short drive from the Perth CBD. We host 21st birthday parties across seven indoor and outdoor areas, from semi-private zones for 20 mates through to full venue takeovers of up to 1,100 guests, with uninterrupted Indian Ocean views from almost every one of them.
A 21st is the first birthday most people actually plan properly, and the venue does most of the heavy lifting. Get it right and the atmosphere is already there when your guests walk in. Get it wrong and you spend the night trying to make a function room feel like a party. Coast is a working beachfront venue rather than a hall for hire, which means the music, the lighting, the bar and the sunset are all built in before you add a single decoration.
Our promise is simple: a 21st that feels like the best night out you have had, with all your favourite people in one place, at a budget that actually works. Whether you are after a semi-private area with a private bar, a cocktail-style party across the main floor, or the whole venue to yourself, our events team will match you to the right space.

Our 21st Birthday Spaces
Coast has seven indoor and outdoor areas configured around three main event spaces, with beachfront access for the big nights. Spaces can be reserved on their own or combined to suit your guest list.
The Beach Cabana
Our newest space, designed specifically for 21sts and engagements. A semi-private area with its own private bar, giving you extra privacy and drink specials without the large minimum spends a full private room usually carries. It sits right beside our resident DJ, who reads the room and tailors the music to your crowd as the night goes on, which alone saves you around $1,000 on hiring your own. Decorate and personalise it however you like, though plenty of groups leave it exactly as is because the space and the bar already look the part.
Cargo Bar
Some of the best ocean views of any bar in Perth. A favourite for cocktail-style 21sts where the sunset does half the work and the bar handles the rest.
Central Coast
Our main floor, easily configured for cocktail-style parties, semi-private reserved zones or larger group celebrations. The most flexible space we have and the one that scales best as guest numbers grow.
The BeachHouse
Our fully private function room, also used as our wedding reception centre. Book it when you want complete privacy, a bigger guest list or a more polished feel for the night.
Port Beach Garden Bar
Outdoor garden space with its own private facilities. Ideal for relaxed afternoon-into-evening 21sts that start in the sun and finish under lights.
A Party Venue, Not a Function Room With a Bar
Most 21st birthday venues in Perth are meeting rooms with a drinks list attached. You hire the space, then spend your budget trying to give it a personality. Coast works the other way around. The venue already has the atmosphere, so your money goes on the things your guests actually notice: the food, the drinks and the space itself.
Our spaces are DJ-friendly, photo-friendly and built for parties that flow rather than parties that sit down. That same setup is why Coast is also one of Perth’s busiest venues for engagement parties and corporate functions. If it works for a room full of colleagues, it definitely works for a room full of your mates.
21st Birthday Packages
Every 21st is tailored to your guest list, your menu and your bar tab. Pick a package, customise it, and lock it in through one conversation with our events team.
- Cocktail-style parties. Canapes, signature cocktails and open-flow space. The most-booked 21st format at Coast.
- Drinks and bar tabs. Set a budget and hand over the bar. Mixed drinks, beer-and-wine tabs or something bespoke.
- Function food packages. In-house party food with dietary requirements covered. People come back to Coast for the food.
- Pizza and casual bites. Wood-fired pizzas, share boards and small plates for a more relaxed night.
- DJ and entertainment. Add a DJ, live music or background playlists, and we will brief the right vibe for a 21st crowd.
- Add-on extras. Cake stands, late-night snacks and photo moments. Your call.
You can see the full food and drinks range on our menu, and our team will build the package around whichever spaces you book.
Budget Flexibility Without the Big Minimum Spend
A 21st should not cost a fortune, and at Coast it does not have to. Whether you are paying, your guests are paying, or it lands somewhere in between, there are five ways to run the night:
- Reserve a semi-private area and let guests purchase their own drinks.
- Pre-order food platters or canapes from as little as around $30 per person.
- Set up a bar tab for as much, or as little, as you would like.
- Host a fully prepaid event with food and drinks included.
- Prepay a minimum spend that can be refunded back to you if guests spend enough on the day.
Our events team walks you through the numbers before you commit, so there are no surprises the morning after. It is the most flexible approach of any beachside venue in Perth.
Getting Everyone There, and Home
Coast sits at 42 Port Beach Road in North Fremantle. Our beachfront car park has over 400 bays and is purpose-designed for seamless bus drop-offs, so if you are organising transport for a big group it is one less thing on your list. For a 21st, where a good chunk of the guest list will not be driving, that matters more than it sounds.
Coast is a tavern-licensed venue, so every guest must be 21 and over. Birthday parties at Coast start with 21sts and go from there.
Why Perth Chooses Coast for 21sts
- Beachfront, not a back room. Indian Ocean views and sunset light across every space, right on the sand in North Fremantle.
- A space for every guest list. From 20 mates in the Beach Cabana to a 1,100-guest full venue takeover, all under one roof.
- A resident DJ who reads the room. Music tailored to your crowd through the night, saving you roughly $1,000 on an external booking.
- Food made here. In-house party food packages with dietary requirements handled, not catering trucked in.
- Budget you actually control. Five different ways to structure the spend, including refundable minimums and guest-paid bars.
- One team, start to finish. Space, food, drinks, timings and set-up handled by the same events crew who run our weddings and corporate events.
Enquire About Your 21st
Weekends in summer book out months ahead. For peak Friday and Saturday dates we recommend enquiring 3 to 6 months out, while weeknights are often far more flexible.
Send through your date, guest numbers and the kind of night you are after, and our events team will be back to you within 24 hours with a tailored proposal. Give us a call on 08 9430 6866, email hello@coastportbeach.com, or browse the rest of our event space hire options to see everything Coast can do.
