Things Needed for a Wedding: The Full Checklist

Two months out, a couple sits down to check what is actually still missing. The full list of things needed for a wedding sorts into four groups: legal paperwork, a vendor team, a budget, and the small items nobody remembers until the week before. Skip a paperwork step and the ceremony cannot legally happen; skip an item in the last group and the day still runs, just with one more thing to improvise on the morning.

The one group with a legal deadline

To marry in Australia, both partners give a notice of intended marriage to an authorised celebrant, say specific words during the ceremony, and are married in front of at least two witnesses over 18.¹ The notice has a fixed window: it must reach the celebrant no earlier than 18 months and no later than 1 month before the wedding date.² Outside that legal timing, the ceremony itself is unrestricted - it can be solemnised on any day, at any time and at any place, as long as the celebrant is physically present.³

This is the one item on the list with a real deadline attached, not just a preference for doing it early. A couple booking a celebrant nine months out, the average booking window for that category, is comfortably inside the notice period.⁴ A couple booking six weeks out is close to the 1-month floor and needs to lodge the notice the same week the celebrant is confirmed.

The vendor team, and what each one actually costs

Most of what a wedding needs is a supplier, not an object. Australian couples book a venue at the highest rate of any category, 92%, followed by a photographer at 90% and hair and makeup artists at 85%.⁵ A celebrant, the one legally required vendor on this list, is booked at 83%, only slightly behind those top three.⁵

The venue is the anchor booking, and it earns that position: it sets the date, the guest cap and the room every later supplier works around, and it takes 46% of the average wedding budget on its own.¹⁶ Everything else in the table above divides the remaining 54%. For the order these get booked in, and what a delay in one costs the rest, see the full vendor checklist.

The budget itself is a thing needed for a wedding

A wedding needs a number before it needs anything else on this list, because every vendor decision downstream reads off it. The average Australian wedding costs $38,252 against a starting budget of around $29,471, a 23% overrun that is close to universal rather than an exception.¹⁷ Set that number knowing it will move, and price the venue - 46% of it - before anything else.¹⁶

The small items that get remembered late

Four categories sit outside the vendor list and outside the ceremony itself, and each one is the kind of thing a couple realises they need with less runway than the vendors above.

A wedding website is now closer to standard than optional: 59% of Australian couples set one up, against 27% who do not and 14% still deciding.¹⁸ Invitations split three ways - 66% physical, 23% email, 11% a dedicated e-vite site - and the format decision needs to happen before the guest list is finalised, not after.¹⁸ A photo booth is booked by exactly half of couples, at an average of $1,038.¹⁹ Furniture and styling hire - the tables, chairs and arbour a venue does not already provide - is booked by 46% of couples at an average of $2,203.²⁰ Bomboniere, the small guest favour, averages $678 nationally, though 44% of couples spend under $5 a guest on it.²¹ And a honeymoon is taken by 88% of couples, averaging $9,684, with 40% leaving straight after the wedding and the rest splitting between a few weeks later and a year or more out.²²

None of these four decide the shape of the wedding day the way the venue or the celebrant do. They are also the four most often forgotten, because nothing forces the decision the way a legal deadline or a venue contract does.

What a wedding does not need

Not every category on a full checklist is something every wedding needs, and treating all of them as equally mandatory is how a budget blows out on categories that were never a requirement in the first place. Professional styling is the clearest case: only 20% of Australian couples hire a stylist, while 54% style the wedding themselves, 16% leave it to the venue and 10% to the florist.²³ Wedding cars sit in the same territory, booked by 36% of couples, well behind every core vendor in the table above.⁵ A photo booth and furniture hire follow the same pattern - real options, chosen by roughly half of couples each, rather than defaults every wedding is missing without them.¹⁹²⁰

Treat every item past the vendor table and the legal paperwork as a decision to make deliberately, not a gap to fill because a checklist listed it. The four groups above cover what a wedding cannot run without. Everything past them is a choice about what this particular wedding is for.

Once every vendor is booked and the small items are decided, the list of things needed for a wedding stops growing and starts needing to be scheduled instead. PlannedBy's run sheet generator turns a confirmed vendor list into a minute-by-minute day, and each supplier gets a view of only their own rows rather than the whole document.

Frequently asked questions

What are the legal things needed for a wedding in Australia? A notice of intended marriage lodged with an authorised celebrant no earlier than 18 months and no later than 1 month before the date², the specific words said during the ceremony, and at least two witnesses over 18.¹

How many vendors does a wedding actually need? There is no fixed number, but booking rates fall off fast after the top few: venue 92%, photographer 90%, hair and makeup 85%, celebrant 83%, then a steep drop to music at 68% and wedding cars at 36%.⁵ Everything below celebrant on that list is a choice, not a requirement.

What percentage of a wedding budget goes to the venue? 46%, the single largest line item by a wide margin.¹⁶ Confirm the venue and caterer before pricing anything else on this list, because both numbers move once the guest cap is set.

Do we actually need a wedding website? Not legally, and not for the ceremony to happen - but 59% of Australian couples set one up.¹⁸ It is the easiest item on this list to build once and forget about.

What do couples forget until the last minute? Bomboniere and photo booth bookings, most often. Both sit outside the core vendor list, so neither has an obvious "book by" date the way the venue or celebrant do.¹⁹²¹
