21 Balloons for your 21st birthday

Plan Your Birthday Party theme

You only turn 21 once, have fun with it! Set your 21st birthday party theme to something that’s all about you, whether you create the ultimate function club and all your friends dress up as something beginning with the first letter of your name or something/someone from the year you were born to celebrate you and your big day!

Tuxedos and Tiaras

This theme is a little like ‘black tie’ but bigger, better and with much more bling. This is the perfect 21st birthday party theme for the Birthday boy or gal who’s a little bit extra and proud of it. Think tiaras, pearls, and diamonds for days. Forget subtly, when it comes to a Tux and Tiara party more is always more.

70’s Disco

Disco themed parties were widely considered faux Pas for the last couple of decades but now they are finally having a moment! If you want to be ahead of the curb, a disco themed 21st birthday party is great way to let loose with your friends and family. Invest in great lighting, fun music and a truly outrageous outfit. We guarantee your disco themed 21st will be the grooviest party of the year.

Intergalactic Rodeo

The space Cowboy theme is about to blow up. How do we know? Because it’s fun, original and also because Kylie Jenner did it. This theme combines intergalactic futuristic alien and wild western vibes. This theme can be interpreted in many different ways, for example when you think of a space Cowboy you might think of Hans Solo or Rey from Star Wars, or you may think you a western style cowboy or girl with glittery cowboy boots and a matching hat. This theme is fun, original and certainly something no-one will forget.

Welcome to The Circus

Another fun 21st theme is ‘Welcome to the Circus’. Set up your birthday party venue like big top, hire a popcorn machine and encourage all your guest to dress up as something strange and magical you might see at the circus. For inspiration, you might want to watch ‘The Greatest Showman’ for some ideas about costumes and overall aesthetics. One idea is to rock a pink wig like everyone’s favourite Instagram it girl ‘Zenyada’ who plays a trapeze artist in the movie.

Your Favourite Colour Party

This is a simple theme that is easy for both you and your guests. Encourage your guests to wear your favourite colour then choose food, drinks, and decor to match. While the theme is simple it is also visually very effective and creates a really cool aesthetic.

Midnight to Midnight

Why not make the most of this milestone and turn it into an all day affair? Ok, so it might not be midnight to midnight, but with The pub opening at 11am you can cruise down after a sleep in (which everyone deserves on their birthday, right?) just in time for lunch.

The Costume Challenge

While a good ol’ costume party is not exactly a revelation, try challenging your guests to dress up only as people who were born on the same day as you. Bizarre costumes guaranteed.

The Surprise (Sort Of)

Sick of researching endless function rooms in brisbaneand fretting about your 21st? Let your family and friends take over the duties, but with one condition. Tell them they can do whatever they want, as long as it’s at the pub. That way you know the venue will be on point, and we’ll make sure your mum doesn’t go overboard with the sentimental stuff.

The Sophisticated Adult Option

Act like the adult that you now officially are and enjoy a private dining experience with your nearest and dearest in one of Brisbane’s best function rooms.

The Boozy Brunch

Unlucky enough to have your 21st fall on a school night? Yeah, that’s most of us. Our suggested 21st birthday party idea is a boozy brunch, instead of a wild night. You still get the celebratory drinks but you aren’t left cursing your adult freedom the morning after.

 The Selfie Scavenger Hunt

In this day and age there’s only one way to preserve your memories, and that’s through selfies. Put together a list and spend the night making memories as you try and fulfil your friends 21 most bizarre selfie challenges.

Make Two Days of It

Fortunately for us lucky Australians, we can begin our celebrations before 21 actually rolls around. Start the celebration a day before your actual birthday to make the most of the occasion.

 The Party With a View

When you think of your birthday and the photos you’ll be looking back on in the years to come, what do you envision? If it’s you and all your friends looking on top of the world, book out a rooftop bar and get that skyline view in your birthday shots.

Scenic Flights

Your 21st is one of the biggest events in your life. Step into adulthood with an epic scenic flight with a few of your closest. Helicopter charters in Brisbane offer a range of chartered and scenic flights around South East Queensland.

The Entertainer

Set your 21st apart by going the route of live entertainment in the pub. With its own stage you can invite along everyone you know to bask in the atmosphere of your live music choices.

21 Drinks

This one is perhaps the most well known and worst idea of them all, according to your liver. We can’t stress this enough, but don’t try and cram all those drinks into one sitting. Enjoy a full day celebration, starting with a champagne breakfast and going from there.

The Colourful Option

Or the not so colourful option, if that’s your thing. Just get everyone to turn up in the same colour, whether it’s a bright green or an all white affair, it’s an easy way to make an impact.

The Un-Deletable Photos

Supply plenty of disposable cameras to your guests and get them to snap all night long. While you’re probably going to cringe at some (ok, most) of the snaps, they’re memories you can enjoy for many years.

The Themed Option

You either love or hate themed parties, but if you’re a fan, there’s no better time to throw one than your 21st. Base your theme on the year you were born and get ready to feel nostalgic.

The Personalised Playlist

Ramp up the sentimental factor of the occasion and get those closest to you to compile a playlist of 21 songs that remind them of you. Incorporate it into the speeches, or play it loud to kick things off.

Enjoy Yourself

This is our most important tip of all for your 21st. Enjoy yourself! No matter what you get up to, take the time to mark the occasion in whatever way suits you.

The letter theme

OK, let’s take a trip down memory lane, way back when we all learnt the alphabet for the first time. Yes, we are referring to ‘Munching Mike’ and ‘Annie Apple’! This is now the foundation for your next party theme – get everyone to dress up as something starting with the first letter of your name or their own name! An instant classic and guaranteed to produce hilarious results, get those creative juices flowing and watch your party kick into over drive – unless your name is Xenia…then you might need to go back to the drawing board.

Masquerade theme

Ooh la la a Masquerade party, notoriously elegant and sophisticated! Who is that beautiful girl with the blonde locks? Who is that handsome gentleman in the tux? Who kissed who? No one will ever know until the masks come off and you have some serious soul searching to do when you realize you’ve been chatting up your cousin for 45 minutes – but hey, talk about an anecdote you’ll be sharing for the next 21 years.

White theme

Forget your LBD, make your 21st a white theme for the ultimate 21st birthday statement. Yes, sister we are entering serious Beyonce and Solange territory! Nothing says suave better than everyone dressed in white, maybe just avoid the red wine…

Great Gatsby

It’s been done many times before, but that doesn’t make it any less fun. Pay homage to the grand party era of the 1920’s with a Great Gatsby themed party. Feathered headbands, sparkling dresses, cocktails and a mix of jazz and ragtime music. You can’t get more festive than that.

Mad Hatters Tea Party

If you have an affinity for the weird and wacky then treat your guests to a mystical, mind-blowing Mad Hatters Tea Party. Mix and match furniture of all shapes and sizes, have white roses painted in red on the table, odd-shaped dishes and cups, quirky cocktails and unique canapes.

Double Denim

For something more laid black, don your double denims and hit the dance floor in comfort. Who knew Jess and Justin would start the party trend of a lifetime. Or in a similar fashion, you can opt for a 90’s theme party when double denim, white sneakers and speed sunnies were a hit. It’s fun, easy and automatically lightens the mood of any party.

21st Birthday Beverage ideas

Now, we’re not recommending that you do this in the space of a few hours. Start your 21st birthday off with a champagne breakfast, make your way to some lunchtime mimosas and see if you can get through 21 drinks before midnight (or before passing out, whichever comes first).

21st Birthday Party Decoration ideas

Digital birthday cards

In lieu of birthday cards, organise a responsible person (i.e mum or dad) to go around the party videoing your friends wishing you a happy 21st birthday. The messages are bound to get funnier through the night.

Memory jar

Have an empty box, blank paper and pens set up somewhere at your 21st birthday party and instruct all of your friends to write down a funny or nice memory they have with you, you can read out them out later in the night for some laughs and “awws”.

Disposable cameras

Place disposable cameras around the party so that people can snap away throughout the night and document your 21st birthday party! This is bound to have funny results that, unlike a bad iPhone selfie or snapchat story, can’t be deleted.


Don’t go in unprepared, make sure you stock up on 21st birthday supplies so that you’re ready for whatever the night throws at you. Tissues for those heart-warming speeches, a sick bag for the next morning and a pizza ready in the fridge for when you stumble home at the end of the night with the munchies.

For girls

For a truly girly girl’s 21st birthday, pamper yourself! Get your hair, makeup and nails done. Splurge on that dress you love so that you can look and feel like the party princess you are for the big night!

 For guys

Guys can pamper themselves too, but if that’s not your idea of fun, you can have more of a “blokey” guy’s 21st birthday by doing whatever you fancy, whether it’s catching an afternoon game or sinking some pre-party beers with your mates.


You’re probably going to get some pretty special gifts for your 21st birthday but if you’re worried you won’t get that special something you have your eye on, start dropping subtle hints to your friends and family leading up to the big day so that your 21st birthday presents won’t end up getting returned.


A fun way to make your 21st birthday unique is to play some games that will not only show how much your friends all know and care about you but will also give you a walk down memory lane. Think up some games that will test your friends’ knowledge of how well they really know you.


Hire a karaoke machine and get ready to belt out all your favourite songs! Not only is karaoke lots of fun but you can totally embarrass your friends when it comes to their 21st birthday with the sneaky footage you took when it was their turn behind the mic.

Party X

Attach a go pro to your person or place it somewhere in the venue at your 21st birthday party or even just tell everyone to take lots of videos. You may not want to watch the footage the next day though, or ever.

Birth-weekend Bender

You only turn 21 once, you may as well milk it for all it’s got! Three nights of partying means triple the fun, right?

Get fancy

Demonstrate your maturity and organise classy canapés and cocktails at the venue for your 21st birthday party so that you can look the part of being a legal adult (even if you don’t quite feel like it yet).
