How to Plan a Wedding: A Step-by-Step Guide
Planning a wedding is not hard, it is just a long list done in the right order. The couples who find it stressful usually do the steps out of sequence: they fall for a venue before they have a budget, or chase styling before they have a guest count. This is the order that works for Australian couples in 2026, from the first conversation to the week of the wedding, with the local legals and timing built in.

Key takeaways
- Plan in this order: budget and guest list, then date and venue, then the legal Notice of Intended Marriage, then vendors, then the details. Each step constrains the next.
- The average Australian wedding costs around AU$38,252 in 2026, and venue plus catering is roughly half of that.
- You legally must lodge your Notice of Intended Marriage at least one month (and at most 18 months) before the ceremony.
- Most couples plan over 12 to 18 months, but a 6-month or even 3-month plan works if you book steps in parallel and flex on date.
- You do not need a full-service planner. A budget tool, a guest tracker and a clear timeline cover most of the work.
The whole process comes down to twelve steps. Do them roughly in this sequence and the wedding plans itself. The timing windows below assume a 12-month-plus engagement, the most common case in Australia. If you have less time, see the compressed timelines further down. And if you have only just got engaged, start with what to do first after getting engaged.
The 12 steps to planning a wedding
Set the budget and agree who is paying
First, before anything else
Every other decision flows from this number. The average Australian wedding costs around AU$38,252, but that figure is meaningless until you know your own ceiling. Have the awkward conversation early: how much will the two of you contribute, and are either set of parents offering? Get a single total, then hold it. The couples who blow their budget almost always skipped this step and backed into a number after they had already fallen in love with a venue.

Draft a rough guest list
Step 2, alongside the budget
Guest count is the single biggest cost lever you control. Catering, venue size, bar, stationery and favours all scale per head, so 120 guests is a fundamentally different wedding from 60. Draft an A-list and a B-list now, even though it feels too early. You do not need final numbers, you need a realistic range, because that range decides which venues are even worth touring.

Choose your date or season
10 to 14 months out
In Australia, peak season is spring (September to November) and autumn (March to April), when the best venues and photographers book out 12 to 18 months ahead. A summer or winter date opens up availability and often unlocks off-peak pricing of 10 to 25 percent. Decide whether you want a firm date or a flexible season, because flexibility is the cheapest negotiating tool you have.

Book the venue
10 to 12 months out
The venue is usually the largest single line item and it anchors your date, your guest cap and your catering, so it goes first among the bookings. Tour three or four, ask what is genuinely included (chairs, linen, staffing, cleaning) and read the wet-weather plan before you sign. Once the venue and date are locked, the rest of the plan finally has a frame to hang on.

Lodge your Notice of Intended Marriage
At least 1 month before the wedding
This is the legal step couples forget. In Australia you must give your celebrant a completed Notice of Intended Marriage (NOIM) a minimum of one calendar month and a maximum of 18 months before the ceremony. Miss the one-month window and you legally cannot marry on your date. Lodge it as soon as you have booked a celebrant.

Book your priority vendors
8 to 11 months out
Photographer, celebrant and caterer book out first, followed by videographer, florist and band or DJ. Book in that order of priority. Ask every vendor the same set of questions so you can compare like for like, and read the payment schedule before you pay a deposit. Deposits are typically 10 to 30 percent, with the balance due one to four weeks before the day.

Send save-the-dates
6 to 8 months out
Once the date and venue are confirmed, tell your guests. Save-the-dates matter most for destination weddings, long weekends and peak holiday periods, when guests need to book flights and accommodation early. A simple digital save-the-date is fine, the formal invitation comes later.

Design the look and book the details
5 to 8 months out
Now the fun part: styling, colour palette, attire and stationery. Choose a palette first because it threads through flowers, table settings, bridesmaid outfits and print. Order wedding attire early, alterations alone can take two to three months. Lock stationery, cake, hair and makeup, and transport in this window.

Send invitations and manage RSVPs
2 to 3 months out
Formal invitations go out six to eight weeks before the day, with an RSVP cut-off about three to four weeks out. Track responses, meal choices and dietary needs in one place, because the final headcount drives your catering guarantee, seating plan and final invoices. Chase the stragglers by phone, every wedding has them.

Build the day-of run sheet
1 to 2 months out
A run sheet is the minute-by-minute timeline of your day, from hair and makeup start through to last drinks. Share it with every vendor and your wedding party so nobody is asking you questions on the morning. A realistic timeline with buffer built in is the difference between a relaxed day and a rushed one.

Finalise seating, payments and confirmations
The final 3 to 4 weeks
Once RSVPs are in, build the seating chart, confirm final numbers with your caterer and venue, and pay the remaining vendor balances on schedule. Reconfirm arrival times and locations with every supplier in writing. This is admin, not romance, but it is what keeps the day from unravelling.

The week of: delegate and let go
The final 7 days
Hand the run sheet to a coordinator or a trusted friend, pack an emergency kit, and step back. By now the planning is done, your job in the last week is to delegate the on-the-day logistics so you can actually be present. Assign someone to carry the rings, the cards and the timeline, and protect your sleep.

How long does it take to plan a wedding?
There is no single right answer, only the right plan for the time you have. The length of your engagement decides how many steps you run in parallel, not whether the wedding is possible. Here is how the same twelve steps compress across three common timeframes, and for the full breakdown by engagement length plus vendor lead times, see how long it takes to plan a wedding.
12+ months engaged
The comfortable pace. Budget and guest list in month one, venue and date by month three, priority vendors by month five, details through the middle, invitations and logistics in the final three months. Best availability and the least stress.
6 months engaged
Doable, but you compress steps 1 to 6 into the first six weeks and book everything in parallel. Be ready to flex on date or venue, since the most in-demand suppliers may already be gone. A shorter guest list helps enormously.
3 months or less
Tight but real, especially for smaller weddings. Prioritise the legals (NOIM minimum one month), a venue and celebrant, then a photographer. Accept an off-peak date, a weekday, or an all-in-one venue package to move fast. Consider eloping or a micro-wedding if the headcount is small.
Whatever your timeframe, a dated checklist keeps the sequence honest. Our free wedding planning checklist breaks every step into month-by-month tasks, and the interactive wedding checklist tool lets you tick them off as you go.
How to plan a wedding on a budget
Most overspending is not extravagance, it is drift: a hundred small upgrades that each felt reasonable. Three levers do most of the work to keep the number down. Cut the guest list, because nearly every cost scales per head. Choose an off-peak date or a weekday for venue and vendor savings of 10 to 25 percent. And pick an all-in-one venue that includes catering and furniture rather than building the day from separate suppliers.
Decide your priorities early. Pour the budget into the two or three things you will remember (often photography, food and the venue) and deliberately go basic on the rest. For the full playbook, see how to save money on your wedding and the typical wedding budget breakdown by percentage.
The most common planning mistakes
The pattern behind almost every wedding-planning regret is doing the steps out of order: booking a venue before setting a budget, leaving the Notice of Intended Marriage too late, underestimating per-head catering, or skipping a realistic run sheet. None of these are exotic problems, they are sequencing errors. We cover them in detail in the wedding planning mistakes to avoid guide.

Start Your Free TrialDo you need a wedding planner, or wedding planning software?
A full-service human planner costs roughly AU$3,000 to AU$8,000 and is worth it for large, complex or short-notice weddings. Most Australian couples, though, do not need one for the months of organising. What they need is structure: a place to hold the budget, the guest list, the vendor records and the timeline, so the twelve steps stay in sequence.
That is what wedding planning software does, at a fraction of the cost. The right tool replaces the tangle of spreadsheets, notes apps and email threads with one source of truth, and a good one bakes in AU pricing and wedding norms so you are not guessing. See our guide to the best wedding planning software for Australia, or compare the leading wedding planning apps in Australia if you want a mobile-first option.
Ivory Lane is built for this exact job: a single AI-assisted planner that covers budget, guests, vendors and timeline, designed for Australian couples with local pricing benchmarks. It is a one-off purchase, not a subscription. See pricing for the detail.
Frequently asked questions
What is the first thing to do when planning a wedding?
Set your total budget and agree who is contributing, before you look at a single venue. Every other decision (guest count, location, vendors) is constrained by that number. Couples who fall in love with a venue first almost always overspend. Lock the budget, then build the wedding inside it.
How long does it take to plan a wedding?
Most Australian couples plan over 12 to 18 months, which gives comfortable access to peak-season venues and photographers. It can be done well in 6 months by booking steps in parallel, and even in 3 months for a smaller or off-peak wedding. The legal Notice of Intended Marriage must be lodged at least one month before the date.
What is the right order to plan a wedding in?
Budget and guest list first, then date and venue, then the legal Notice of Intended Marriage, then priority vendors (photographer, celebrant, caterer), then save-the-dates, styling, invitations, the run sheet, and finally seating and payments. The order matters because each step constrains the next.
How much does it cost to plan a wedding in Australia?
The average Australian wedding costs around AU$38,252 in 2026, though couples spend anywhere from under AU$10,000 for a micro-wedding to well over AU$60,000. Venue and catering typically make up close to half the total. A clear budget and guest cap are the two strongest levers for controlling the number.
Can I plan a wedding myself without a planner?
Yes. Most Australian couples plan their own wedding using a budget tool, a checklist and a clear timeline, and bring in a paid day-of coordinator for the wedding itself. A dedicated wedding planning tool handles the structure (budget, guests, vendors, timeline) so you do not need a full-service planner for the months of organising.
When should I book my wedding venue?
Book your venue 10 to 12 months before the date for a peak-season (spring or autumn) wedding, since the most popular Australian venues fill 12 to 18 months ahead. For an off-peak or smaller wedding you can often book within 6 months. The venue should be one of your first bookings because it anchors your date and guest cap.
