Wedding Planning List: What to Book and When

Your wedding planning list has roughly 24 months to work with - the average Australian engagement.¹ What compresses that window is that the suppliers who shape the day most - venue, photographer, celebrant, musicians, hair and makeup - are all booked within the first 13 to 15 months.² The six phases below are ordered by deadline pressure, not by how much time each one takes.

Phase 1 contains the only item on the list set by law rather than by supplier availability. Every other deadline is a function of demand.

Phase 1: Engagement to 18 months out

Set a budget and a season before you talk to anyone.

Australian couples start with a budget near $29,471 and land at $38,252 on average, a 23% gap that opens mainly through venue and catering quotes.⁸ Knowing your season before the first venue call means you arrive knowing whether the month you want carries peak demand.

Spring (September to November) accounts for 38% of all Australian weddings, with October alone taking 17% of the year.³ The most popular single date in 2025 was 25 October, with 2,035 marriages.⁹ A Saturday in that month is rationed by venue capacity, and venues book an average of 11 months out.² If you want one of those Saturdays, the venue conversation needs to start before you have a confirmed date.

Lodge the Notice of Intended Marriage.

You must give a notice in writing to your authorised marriage celebrant at least one month and no more than 18 months before the wedding.⁴ This is the one deadline on the list with a statutory floor and ceiling. Celebrants handle it at an initial meeting, but it requires a date to have been set, so it follows the venue decision rather than the engagement itself.

Start the guest list draft.

Australian couples plan for an average of 108 guests and actually invite 85.⁵ The 23-guest gap opens when venue quotes arrive and budget pressure forces cuts. A working draft at this stage gives you a headcount range for venue site visits - most venues price per head, so you need a number before quotes are comparable.

Phase 2: 18-12 months out

Book the venue.

Venues are booked an average of 11 months before an Australian wedding.² That is the average - a venue you want for a peak spring Saturday may need to be confirmed 14 or 15 months out. The guest list draft feeds directly into this: venue capacity is why the draft exists.

Book the photographer and celebrant.

Both are booked at 9 months on average.² In the buying cycle Australian couples actually follow, celebrant sits at position 4 and photography at position 5, both behind the venue but ahead of every other category.⁷ Book them in the same window as the venue confirmation, before the date sends ripples through their availability.

---

Phase 3: 12-9 months out

Book musicians and hair and makeup.

Musicians and hair and makeup artists are both booked at 9 months on average - the same window as the photographer.² A musician's Saturday availability is constrained by the same October peak as the venue. Book them in the same month as the photographer rather than after, because they are drawing from the same limited pool of weekend dates.

Finalise the guest count.

With venue capacity confirmed and catering quotes in hand, the guest list can close. The count of 108 becomes the count of 85.⁵ Three things cannot be written until this number is fixed: catering headcount, the seating plan, and the invitation run.

---

Phase 4: 9-6 months out

Book wedding cars.

Wedding cars carry the shortest lead time of any supplier category - booked an average of 6 months before the wedding, compared to 9 months for photographers and celebrants.² Book them after the venue is confirmed, because the ceremony and reception locations determine the transport route and timing.

Send save the dates.

With venue locked and guest count set, this is when the draft becomes a delivery list. For guests travelling interstate or from overseas, send at this point.

Brief flowers, cake and decor.

No average booking window is published for these categories, but most florists and cake makers work to 3-6 month lead times for anything complex. Briefing them in this phase means availability is confirmed before the seating plan and run sheet need their timing.

---

Phase 5: 6-3 months out

Build the seating plan and start the run sheet.

With confirmed headcount and the venue's table layout, the seating plan can be drafted. The run sheet - the minute-by-minute schedule of the wedding day - follows from both, because dinner service timing depends on how the room is set and how the photographer's timeline fits around it.

The PlannedBy run sheet generator derives the full day from a single ceremony time. For a 3:00 PM ceremony, it returns getting ready at 11:00 AM, venue departure at 2:15 PM, guest arrival at 2:30 PM, family photos at 3:30 PM, reception at 6:00 PM and send-off at 11:00 PM. Every row is a calculated offset from the ceremony time, not a typed entry.

Confirm all supplier timing.

A timing confirmation pass now surfaces conflicts before they are in a signed brief. The three most common sources of conflict on a run sheet are the venue's pack-down window, the caterer's last-service time, and the photographer's contracted end time.

---

Phase 6: Final month

Share the run sheet with every supplier.

A finished run sheet goes to the venue coordinator, photographer, videographer, caterer, celebrant, hair and makeup, musicians and transport. The PlannedBy run sheet generator produces a shareable link, so all suppliers see the same document and any last-minute timing change updates everywhere at once.

Prepare a day-of emergency kit.

One container kept in the car of whoever manages the day: needle and thread, pain relief, stain remover, band-aids, a portable charger and printed copies of every supplier's contact number. Print the contacts - mobile coverage at remote ceremony venues cannot be relied on.

Confirm the legal paperwork.

Check with your celebrant that the marriage certificates are prepared and the witness arrangements are in place. Two witnesses over 18 must be present to sign on the day.⁴

What the planning stressors tell you about this list

Budget pressure accounts for 24% of planning stress among Australian couples, guest list 15%, and keeping up with tasks 10%, according to the Easy Weddings 2026 survey.⁶

The list above addresses the tasks column directly - every phase produces a concrete deliverable - but not the budget gap. Budget stress opens when quotes arrive and the original figure proves short. A planning list that treats the budget as a fixed constraint rather than an estimate reduces this only indirectly: by getting venue quotes early, when there is still time to adjust the plan.

Frequently asked questions

When should you start planning a wedding in Australia?

Start the moment you have a rough season in mind, before any supplier conversations. For a spring Saturday in October - which carries 17% of Australian weddings and fills first - a venue needs to be confirmed roughly 13-14 months before the date.³² A 24-month engagement is enough runway if the first six months are active ones.¹

What is the first item on a wedding planning list?

Set a budget and a season before booking anything. Every supplier quote depends on knowing the month - peak spring months cost more and have less availability - and the budget sets the ceiling on what you can actually commit to. The Notice of Intended Marriage comes second: it requires a date to exist, so it follows the venue conversation.

Does Australian law require any paperwork before the wedding?

Yes. A Notice of Intended Marriage must reach your authorised celebrant at least one month and no more than 18 months before the wedding.⁴ That is a statutory window with no exceptions in standard circumstances. Everything else on the list is deadline pressure from the market, not from legislation.

How long does it take to plan a wedding in Australia?

The average Australian engagement runs 24 months.¹ Most of the active work falls in the first six months - venue, photographer, celebrant and musicians are all booked in that window - and the final three months are spent on confirmation and detail rather than new sourcing.

What gets booked last?

Wedding cars, at an average of 6 months before the wedding.² Flowers, cake and decor do not have a published average in Australian data, but most operators work to 3-6 month lead times. The run sheet and seating plan belong to the final quarter, though they cannot begin until guest count and venue layout are both confirmed.
