Most wedding checklists are inventories. They tell you to book a photographer and order stationery without ever explaining which decisions actually shape the day. This one is ordered by time, but each stage also notes the choice that matters most at that point.
Twelve months out
Set the budget and decide who is contributing before anything else. Every later decision depends on it.
Draft the guest list next, not the venue. The number of people determines the venue, the catering and the cost, so choosing a room before you know who is in it usually means revisiting the decision.
Book the venue and the celebrant once the guest number is realistic. In Australia the Notice of Intended Marriage must be lodged with your celebrant at least one month and one day before the wedding, and no more than eighteen months prior, so raise it early.
The decision that matters here: how many people you actually want in the room. A smaller list is not a lesser wedding.
Nine months out
Book the photographer, videographer and any entertainment. Good suppliers in Sydney, Melbourne and regional wine regions are often booked more than a year ahead for peak season.
Start thinking about accommodation and transport if guests are travelling.
The decision that matters here: whether your day is built around a schedule or around time with people. Everything you book from now either protects that time or eats it.
Six months out
Order attire and allow for alterations. Confirm the caterer and menu, including dietary requirements. Send save the dates.
Begin planning the ceremony itself: readings, music, who will stand with you.
The decision that matters here: who you are asking to play a part. Roles carry meaning and the people you choose will remember being chosen.
Three months out
Send invitations with clear RSVP dates. Confirm the run sheet with your venue and photographer. Book hair and makeup trials. Write your vows early rather than the week before.
Start the seating plan once RSVPs begin arriving.
The decision that matters here: how guests will find their way through the day. Clear information makes people feel looked after before they arrive.
One month out
Lodge or confirm all paperwork with your celebrant. Finalise numbers with the caterer. Confirm every supplier in writing, including arrival times and contact numbers.
Write anything you want to say to people individually. Speeches, notes, cards and messages take longer than expected and they are the first thing to be abandoned in a busy final fortnight.
The decision that matters here: what you want people to leave with. Not what they eat, but what they know about why they were invited.
The final week
Confirm the timeline with everyone who has a job on the day. Pack an emergency kit. Delegate the small logistics to someone reliable so neither of you is fielding questions during the morning.
Deliberately book nothing for the day before. Protecting one quiet evening together is the single most common piece of advice from couples looking back.
The week after
Thank your suppliers. Write thank you cards while the details are fresh, ideally within a month. Read the cards you were given properly, in your own time.
What checklists usually miss
A wedding runs on logistics but it is remembered for the relationships in the room. If the planning stays entirely in spreadsheets, the people part gets pushed to the last fortnight when there is no capacity left for it.
Build the people decisions into the calendar the same way you book a florist. Decide early who you want to acknowledge, and give yourself months rather than days to do it properly. It is also worth reading our guide to planning a wedding timeline, which covers how to build the day itself so there is room to breathe.
