Congratulations. You're the Best Man - Now What?

Being asked to be the best man is one of those moments you'll remember for a long time.

Whether it happens over a beer, during a fishing trip, or in the middle of an ordinary conversation, it usually catches you off guard. You shake his hand, tell him you're honoured, and immediately start picturing yourself standing beside him on the wedding day.

Then, somewhere between saying yes and the engagement party, reality kicks in.

You've just accepted a job.

Not a paid one, unfortunately.

A job that comes with group chats, speeches, bucks party planning, family politics, budgets, last-minute phone calls and just enough responsibility to make you wonder if you should've asked for a position description first.

The good news is that the best man duties aren't about being perfect. They're about making life easier for the groom, keeping everyone organised, and helping create memories that he'll still be talking about years after the wedding.

If you've never done it before, don't stress. Here's what the best man duties actually involve and how to absolutely nail them.

Best man duties start well before the wedding

Most people think the best man duties begin on the wedding day.

Hold the rings.

Straighten the groom's tie.

Deliver a great speech.

Keep everyone calm.

Those things matter, but they're only the final chapter.

The real work starts months earlier, long before anyone walks down the aisle. One of your biggest jobs is making sure the lead-up to the wedding is just as memorable as the day itself. That means checking in on the groom, helping where you can, and, of course, organising a bucks party that actually reflects who he is.

It's easy to get caught up trying to create the biggest or wildest celebration, especially when social media is full of outrageous weekends away and over-the-top itineraries. The reality is that most grooms don't care about having the most expensive bucks party. They care about spending quality time with their favourite people before one of the biggest moments of their life.

That's why understanding the groom is one of the most important best man duties you'll have.

Best man duty #1: Work out what the groom actually wants

Here's something you'll notice almost immediately.

Most grooms are hopeless at answering questions about themselves.

Ask him where he'd like to go.

"I'm easy."

Ask what activities he'd enjoy.

"Whatever the boys reckon."

Ask how big he'd like the group to be.

"I don't really mind."

It's generous, but it leaves you trying to organise an entire celebration based on absolutely no useful information.

Rather than asking broad questions, think about the bloke you've known for years. Is he someone who loves a round of golf followed by a long lunch? Would he genuinely enjoy a brewery tour, or is he more likely to prefer something competitive like go karting or clay shooting? Maybe he'd rather escape for a weekend away than spend twelve hours bouncing between bars.

The best man duties aren't about recreating someone else's bucks party. They're about creating one that feels like your mate. Once you stop worrying about what's trendy and start focusing on what suits the groom, the planning becomes much more straightforward.

Best man duty #2: Accept that you've become an event planner

Nobody really warns you about this part.

One minute you're feeling pretty pleased with yourself for being chosen as best man. The next you're comparing accommodation, requesting quotes, chasing RSVPs and wondering why organising ten adults feels harder than coordinating a school excursion.

The group chat certainly doesn't help.

There's always one bloke who's ready to book everything immediately. Another insists he's happy with whatever. Someone reads every message without replying, while another disappears for three weeks before asking whether anything has been organised yet.

It's enough to test anyone's patience.

One of the smartest approaches is keeping your communication simple. Instead of asking open-ended questions like, "What do you boys want to do?", narrow the options and ask people to choose between two or three ideas. You'll get better responses, make decisions faster and spend far less time scrolling through hundreds of messages that somehow never answer the actual question.

Good organisation is one of those best man duties nobody really notices when it's done well, but everyone notices when it isn't.

Best man duty #3: Talk about the budget early

Money conversations aren't particularly exciting, but they're one of the most important parts of planning a successful bucks party.

Every friendship group is different. Some blokes are saving for houses, some have young families, others are travelling for the wedding itself. Assuming everyone is comfortable spending the same amount is one of the quickest ways to create unnecessary stress.

The best approach is honesty.

Work out a realistic budget before you start booking activities and be upfront about what's included. Most people appreciate knowing exactly what they're committing to rather than being surprised by extra costs later.

Remember, a great bucks party isn't measured by how much money you spend. It's measured by the people who are there and the memories you create together.

Keeping things realistic is one of the most underrated best man duties, and it's often the difference between an event everyone can enjoy and one that leaves people quietly pulling out at the last minute.

Best man duty #4: Stop trying to keep everybody happy

This might sound harsh, but somebody needs to say it.

No matter what you organise, someone will have a different opinion.

One bloke would've preferred golf.

Someone else wanted a brewery.

Another thinks the weekend should've been longer.

That's completely normal.

The mistake many first-time organisers make is trying to please every single person in the group. Before long, you're changing plans, delaying bookings and creating more work for yourself than necessary.

The person you need to impress isn't the loudest bloke in the group chat.

It's the groom.

If he finishes the weekend saying he had an incredible time, you've done your job. The rest is just background noise.

Best man duty #5: Plan a bucks party he'll actually remember

For a lot of people, organising the bucks party is the biggest item on the list of best man duties. It's also the one that tends to cause the most stress, simply because everyone has an opinion on what makes a great celebration.

The truth is, the best bucks parties aren't necessarily the biggest or the wildest. They're the ones that feel personal. Think about the groom's interests, the people he wants around him, and the sort of stories he'll still be laughing about years from now. Some groups love an action-packed day of clay shooting and go karts before heading out for dinner and drinks. Others would happily spend an afternoon on a brewery tour, a golf course or a boat, with plenty of time to catch up and enjoy each other's company.

One of the easiest traps to fall into is trying to squeeze too much into the itinerary. It can be tempting to book breakfast, three activities, dinner, multiple bars and a nightclub because you want everyone to feel like they're getting value for money. In reality, that usually means everyone spends the day watching the clock rather than enjoying themselves.

Leave room for conversations. Leave room for unexpected moments. Some of the funniest stories happen between activities, not during them. A relaxed schedule almost always creates a better atmosphere than one where everyone is rushing from one booking to the next.

Best man duty #6: Write a speech that's actually about the groom

Let's clear something up straight away.

The best man's speech isn't your chance to become a stand-up comedian.

It isn't about proving you're the funniest bloke in the room, and it definitely isn't the time to tell every embarrassing story you've been saving since high school.

A great speech should leave the room laughing, but it should also leave them understanding why the groom chose you to stand beside him.

Start with a great story. Talk about your friendship. Share something that sums up who he is, not just something that happened after a big night out. If you include a joke, make sure the groom is laughing too. If he isn't, it's probably not the right joke.

Most importantly, remember that this is one of the biggest best man duties because it's one of the few moments during the wedding where everyone is listening. The speech should celebrate the groom, welcome the new couple, and leave people smiling rather than cringing.

If you're wondering whether a story crosses the line, it probably does.

Best man duty #7: Be the calm one on the wedding day

By the time the wedding arrives, months of planning have already happened.

The bucks party is over.

The suits are hanging up.

The speeches are written.

Now your job changes.

One of the final best man duties is simply being the person the groom can rely on. Make sure everyone's where they need to be, keep an eye on the schedule, answer the little questions before they become big problems, and help create a relaxed atmosphere while everyone gets ready.

The groom will probably be nervous, even if he pretends he isn't. A calm best man makes a huge difference, whether that's grabbing him a coffee, reminding him everything is running on time, or simply making him laugh while everyone's waiting for the ceremony to begin.

It's amazing how many little things happen behind the scenes on a wedding day. Being present and paying attention often helps far more than trying to solve problems that don't actually exist.

You don't have to do it all yourself

Here's something a lot of first-time best men forget.

You're allowed to ask for help.

The best man duties don't mean carrying every responsibility on your own while everyone else sits back and watches. If one mate is great with organising accommodation, let him handle it. If someone else enjoys planning activities, get them involved. Even something as simple as asking another groomsman to keep track of payments can take a huge amount of pressure off your shoulders.

Good organisers don't do everything themselves.

They know when to involve other people.

FAQs about best man duties

What are the main best man duties?

The main best man duties include organising the bucks party, supporting the groom throughout the lead-up to the wedding, helping coordinate the wedding day, looking after the rings if required, and delivering a memorable speech.

Is the best man responsible for organising the bucks party?

Traditionally, yes. While other groomsmen often help, the best man usually takes the lead on planning the bucks party and making sure everything runs smoothly.

How early should a best man start planning?

It's a good idea to begin organising the bucks party around two to four months before the event. This gives everyone enough time to budget, organise leave, and lock in accommodation or popular activities.

Does the best man pay for the groom?

Every friendship group is different, but it's common for the group to contribute towards the groom's costs for the bucks party. Discussing expectations early helps avoid any awkward surprises.

What should a best man avoid doing?

The biggest mistake is making the celebration about yourself instead of the groom. Avoid overcomplicating the itinerary, leaving bookings until the last minute, or using your speech as an excuse to embarrass him.

Does the best man have to give a speech?

In most Australian weddings, yes. It's one of the traditional best man duties and gives you the chance to celebrate your friendship, welcome the couple, and share a few memorable stories with their family and friends.

Final thoughts

Being asked to be the best man is a privilege, but it's also a responsibility that most people underestimate. Between the bucks party, the speech, the planning and the wedding day itself, there's a fair bit to think about.
