How much does it cost to keep a skip bin longer?

Keeping the same bin for 28 days instead of 3 costs a median of 68% more — but the first few extra days are usually free. On 2026-08-30 we priced one identical 4 m³ general-waste skip across 60 Australian postcodes at seven different hire lengths, from the same live supplier network, for the same delivery date. In 36 of those 60 postcodes a 7-day hire cost exactly the same as a 3-day hire — not a dollar more. Past about 14 days the price climbs steeply. The extension is not sold as a daily rate, and no single dollars-per-day figure describes it.

The full measured ladder is below, along with the four postcodes where keeping the bin longer costs nothing extra at all — and one where 28 days is cheaper than 14.

What each hire length actually cost

Same bin, same waste type, same delivery date, 60 postcodes:

The two right-hand columns are the honest ones. They are paired: for every postcode we compared that postcode's own 28-day price against its own 3-day price, then took the median of those 60 differences. The "median price" column is a separate calculation — the middle price across 60 postcodes at that one duration. The two do not add up ($443 + $330 = $773, not $764) and they are not meant to: one is the middle of a list of prices, the other is the middle of a list of differences. We publish both because the first tells you what a bin costs and the second tells you what an extra day costs, and only the paired figure can be trusted to compare like with like.

It is not a daily rate

Guides in this category commonly quote an extension rate somewhere between about $20 and $100 a day. We did not audit those pages and make no claim about any particular one — but no flat daily rate survives contact with the measured data. Here is the actual marginal cost of each extra day, by window:

The median cost of day 5 and of day 7 is zero. The median cost of a day in the fourth week is $17.71. A single daily rate cannot describe a curve that starts at nothing and ends at nearly eighteen dollars a day — and if you spread the whole 3-to-28-day increase evenly you get a median of $13.20 a day, a number that is wrong at both ends and right nowhere in the middle.

What is actually being sold is a set of price bands. Hire length steps at thresholds, the same way the price steps at supplier zone boundaries. Between two thresholds, extra days are free.

36 of 60 postcodes charge the same for 3 days as for 7

This is the single most useful thing in the dataset, because it means most people do not have to guess right. In 36 of the 60 postcodes measured, the 3-day, 5-day and 7-day prices were identical to the dollar. In 44 of 60, 3 days and 5 days were identical.

The other 24 postcodes do charge more to go from 3 days to 7 — by up to $114 on this bin. So it is worth checking rather than assuming, but the odds are with you: if your job might take five days rather than three, in three postcodes out of five it costs nothing to book the longer hire up front.

Booking the longer hire from the start is also the only version of this that is priced. A bin already on the ground that you need to keep is a change to a live booking, not a listed rate.

How wide the spread gets

The 68% median hides an enormous range. Across the 60 postcodes, the cost of moving from a 3-day to a 28-day hire ran from +4.3% to +150.2%:

The dearest in the sample was 3754 (Doreen and Mernda, VIC): $329 for 3, 5 or 7 days, and $823 for 28 days — +150.2%, an extra $494 on the same bin. The cheapest extension was 4500 (Bray Park and Brendale, QLD): $609 for 3 days and $635 for 28, an extra $26 for twenty-five more days.

By state, the 25 Victorian postcodes in this sample carried a median 28-day uplift of +92.0%, the 8 Queensland postcodes +69.3%, and the 27 New South Wales postcodes +58.7%. Those state figures rest on small and uneven samples and should be read as indicative only.

Four postcodes where keeping it longer costs nothing more

In 4 of the 60 postcodes, a 28-day hire cost no more than a 14-day hire. In three of them — 3629 (Mooroopna), 3631 (Arcadia) and 3840 (Hazelwood) — the price is $823 for a 10-day hire and still $823 at 28 days. Eighteen extra days, no extra charge.

And in 4500 (Bray Park and Brendale, QLD) the ladder actually goes backwards: $609 for 3 days, $658 at 10 days, $705 at 14 days, then $635 at 21 and 28 days. A 28-day hire there was $70 cheaper than a 14-day hire on the day we measured it.

We publish that because it is what the engine returned, and because it is the clearest possible demonstration that hire length is priced in bands rather than by the day. It is a quirk of one supplier’s price ladder, not a standing offer, and it may not survive the next price change. It also means the only reliable way to find out is to price the exact hire length you want, in your own postcode.

If your job might run over

• Ask for the longer hire when you book. In 36 of 60 postcodes, going from 3 days to 7 costs nothing, and in 11 of 60 even 10 days costs nothing extra.
• The 7-to-14-day window is cheap; the fourth week is not. The median jump from 3 days to 14 is $54. The median jump from 3 days to 28 is $330.
• Do not assume a per-day rate. On this data the marginal day costs anywhere from $0.00 to $53.71 depending on which day it is and where you are.
• 28 days is the longest hire we measured, and 30 days is the longest our supplier network will hire a bin for. Longer jobs are handled as a second bin or a swap, not an extension.
• Prices move and are set per postcode. Everything here is a snapshot of one date; the only figure that applies to your job is a live quote for your postcode.

Method. One 4 m³ general household waste skip, priced at 3, 5, 7, 10, 14, 21 and 28 days in each of 60 Australian postcodes, quoted from the Local Skip Bin Hire live booking engine on 2026-08-30 for a 2026-09-07 delivery. Every one of the 420 prices came from the live supplier network; prices the engine could not source live were excluded rather than substituted from a catalogue, and no catalogue price appears anywhere on this page. The headline figure is a paired per-postcode median: for each postcode we took its own 28-day price minus its own 3-day price as a percentage of its own 3-day price, then took the median of those 60 values, giving +67.99%, published as +68%. We chose this method because each postcode is only ever compared with itself, so a change in which supplier zones happen to be priced cannot move the number. We deliberately did not use the alternative of dividing the national 28-day median price by the national 3-day median price, which gives +72.5% on the same data but compares two separately-computed medians that need not come from the same postcodes, and so describes no actual customer. The 3-day price is the baseline throughout because it is the shortest hire measured; percentages against a different baseline would be different numbers, which is why ours is named. Against each postcode’s own 7-day price, the same paired method gives +61.5% on the same data — a different baseline, not a different finding. Limitations: this is one bin size, one waste type and one delivery date, and the sample is 27 New South Wales, 25 Victorian and 8 Queensland postcodes — there are no South Australian, Western Australian, Tasmanian, Northern Territory or ACT postcodes in it, and we make no claim about hire-length pricing in those states or at other sizes. The 60 postcodes collapse into 25 distinct price ladders, because postcodes sharing a supplier zone share an identical ladder, so the effective sample is smaller than 60. This is a snapshot as at 2026-08-30 and makes no claim about how prices have moved over time.
