How many flyers do I need for a letterbox drop?
Built for the people who actually do this: a real estate agent running a just-listed or just-sold campaign, a plumber or electrician letting the street know who did the job next door, a new café or local business trying to be known in its own suburb. Search a suburb or a postcode and this gives you its real dwelling count from the Australian Bureau of Statistics — not a density guess — then adds up as many suburbs as your campaign covers and shows the flyer run that fits, priced straight off our tier list. Nothing is uploaded; the count runs off a public dataset loaded into your browser.
Which suburbs are you dropping into?
Start typing a suburb, or type a postcode, and pick from the list. Add as many as you like — four adjoining suburbs is one print run, not four.
In this campaign
2021 Census, Mesh Block counts
Automated, and only as good as the Census
If a suburb looks wrong, tell us
This runs off a public Australian Bureau of Statistics dataset, not a live count, and Census boundaries occasionally split or rename a suburb in a way the data does not reflect cleanly. If a figure looks obviously off for a place you know, we would rather hear about it than have it sit there wrong — reply to any email or call (02) 5302 3372.
Where the number comes from, and how true it is
The honest version, not the marketing one
Every suburb in Australia is divided by the Bureau of Statistics into Mesh Blocks — the smallest area the Census reports on, usually 30 to 60 dwellings each. The 2021 Census counted every dwelling in every one of the country's 368,286 Mesh Blocks, and published the result under a CC BY 4.0 licence. This tool sums the Mesh Blocks inside each suburb's own Census boundary and shows you the total. It is not a rule of thumb about how many houses fit in a circle — it is the count, for that specific suburb, as measured.
That is a meaningfully different thing from a density estimate. A generic "12 dwellings per hectare" guess is out by two or three times depending on whether the suburb is a high-rise centre or a rural fringe; the actual count does not care which one it is.
Two honest limits, and neither is hidden in fine print. First, this counts dwellings, not letterboxes: a block of units usually shares one bank of boxes at the entrance, so a suburb with a lot of apartments will have noticeably fewer physical letterboxes than the dwelling figure suggests. Second, Australia Post's own published figures put roughly one letterbox in four under a "no advertising material" sticker, and this count cannot see those — treat the number here as the upper limit of who is home to receive a flyer, not a promise of how many will accept one. And because it is a 2021 figure, a new estate built since then will read lower than it now is.
Who this is built for
Three drops, three different quantities
Real estate agents
A just-listed or just-sold drop to the streets around a property is how one sale turns into the next appraisal. You rarely need the whole suburb — count the streets you will actually walk.
just listed · just sold · open home
Plumbers, electricians and other tradies
Finished a job? The neighbours are the warmest lead you will ever get — they have seen the van and can see the work. A street or two around the job, not the whole postcode.
just worked on your street
New and growing local businesses
A new café, cleaner, gardener or studio that wants the suburb to know it exists. This is where the whole-suburb figure above is the number to work from.

How many flyers should I actually order?
Whole suburb, or just the streets around one job
If you are letting people in a suburb know you exist — a new trade business, a shop opening — the whole-suburb figure above is the number to work from, in the flyer quantity that covers it.
If you have just finished one job and want the immediate neighbours to see it — the classic real estate or tradie drop — you do not need the whole suburb. A walk of two to three streets around a single property is commonly somewhere between 100 and 300 homes, well under our smallest run of 250 flyers. Count the streets you actually intend to walk and round up; the calculator's suburb total is there for when you are covering more ground than that.
Common questions
How many flyers should a real estate agent order for a just-listed or just-sold drop?
Most agents do not need the whole suburb — a walk of two to three streets around the property is commonly 100 to 300 homes, inside our smallest run of 250 flyers. Use the calculator's suburb figure when you are covering more ground than that, for a new-to-the-area campaign rather than one listing. See what agencies usually order for boards, A-frames and cards to go with it.
How many flyers does a plumber or other tradie need for a local letterbox drop?
The same rule as a real estate drop: the streets immediately around the job, not the postcode. A finished job is the best reason a neighbour will keep a flyer — they have already seen the van and the work. See what tradies usually order for vehicle signage and cards to go with it.
Is a letterbox drop still worth it for a local business?
Trade estimates commonly cited for unaddressed advertising sit around 0.5 to 1% response — a planning figure from general industry commentary, not a number we can promise for your letterbox, your offer or your suburb, which is why it is not built into this calculator. What a drop reliably does is put your name in front of everyone in a defined area at a known cost, which is the same job a local Facebook or Google ad does at a less predictable one.
Is this a letterbox count or a household count?
A dwelling count, from the 2021 Census — the nearest true public figure to a letterbox count that exists. It is not the same thing: a block of units usually shares one bank of boxes, and roughly one letterbox in four nationally carries a no-junk-mail sticker Australia Post cannot see through. Treat the figure as an upper limit, not a guarantee of delivery.
Can I plan a drop across several suburbs, or a whole postcode?
Yes — add as many suburbs as you like and the calculator sums them into one dwelling count and one flyer run, which is how a campaign is actually printed. Search a four-digit postcode and it offers to add every suburb in it at once. There is no reason to print four separate jobs for four adjoining suburbs; one run at the higher quantity is cheaper per flyer than four small ones.
Can I search by postcode instead of suburb name?
Yes. Type the four digits and you get every suburb in that postcode, with its own dwelling count, plus the option to add the lot. Postcodes and suburbs are not the same shape — a postcode usually covers several suburbs and a few suburbs straddle two postcodes — so the tool shows you which suburbs are in play rather than quietly assuming.
DL, A5 or a folded A4 — which should I print?
DL (99 × 210mm) and A5 (148 × 210mm) cost the same and both fit a letterbox flat, so pick on how much you have to say: DL for one message, A5 for a photo and a message. Go to a folded A4 down to DL when one sheet genuinely is not enough — several listings, a full price list, before-and-afters. It costs more per door, and it is scored before folding so the stock creases cleanly instead of cracking along the fold.
Why only NSW, QLD and VIC?
Because that is where we print flat print, and a letterbox run is planned around where it is printed. The rest of the country can still order the flyers; it is the suburb-by-suburb dwelling counts that stop here, and adding every state would make the dataset several times larger.
My suburb is not coming up.
Try fewer letters, or search the postcode instead — the search matches any part of a name, so three or four letters is usually enough. The Bureau of Statistics adds a bracketed qualifier to about one suburb in seven where the name repeats elsewhere, and a postcode gets past that in one step. If it genuinely is not there, (02) 5302 3372 and we will look it up from the same source directly.
Does the count include apartments and townhouses?
Yes — every private dwelling the Census counted, house or unit. That is exactly why a high-density suburb's dwelling figure can overstate its letterbox count more than a suburb of standalone houses does: shared entries mean shared boxes.
How is the flyer price worked out?
Straight from the same tier list the flyers page prices from — whatever this tool recommends is the figure you would see there, GST included, before freight. It updates automatically if our prices change.
Can I target a radius instead of whole suburbs?
Not yet on this page — it works in whole suburbs and postcodes for now. For one street or a small pocket, order our smallest run of 250 flyers and count the doors yourself; for an area that is bigger than one suburb but not a clean group of them, ask us and we will size it properly.
