Where Melbourne's apartment glut is building

Future apartment supply is one of the clearest, and least talked-about, signals of price and rent risk for a buyer or investor. Melbourne has 71 suburbs with at least 150 apartments currently under construction or firmly committed — 67,198 apartments in total — and in 14 of them, that pipeline is large enough to more than double the number of apartments already standing.

This isn't a list of "bad" suburbs. New supply is also where you'll find more choice and often sharper prices. But a lot of new stock landing in a small existing market is the textbook setup for softer rents and slower capital growth while it's absorbed — and that's worth knowing before you buy an apartment there, not after settlement.

The headline numbers

• 67,198 apartments recorded as under construction or firmly committed across Greater Melbourne
• 71 suburbs have 150 or more apartments in the pipeline
• 7,365 of those are landing in Docklands alone — more than any other suburb
• 14 suburbs have a pipeline large enough to more than double their existing apartment stock

How to read this table

"Committed" means apartments the Victorian Government's Urban Development Program (UDP) records as either Under Construction or Firm — a genuine, hard count of major projects, not speculative proposals. "Existing apartment stock" is estimated (households in the suburb × its apartment share, from the 2021 Census), so the "% of existing stock" column is indicative rather than exact — treat it as a strong directional signal, not a precise figure.

That estimation matters most for suburbs where the existing base is small. A handful of suburbs below — Ringwood East, Spotswood, Mulgrave, Narre Warren — show percentages in the hundreds, because their existing apartment stock is tiny (under 250 apartments) and even a modest pipeline looks enormous next to it. Read the raw committed count alongside the percentage for those: Mulgrave's "802%" is 171 new apartments against an estimated 21 existing, not a market being swamped the way Docklands' 87% (7,365 against 8,419) is.

What the data shows

By raw volume, the pipeline is overwhelmingly inner-city: Docklands, the City of Melbourne and Southbank alone account for almost 28,900 of the 67,198 apartments in the pipeline — well over a third. If you're just counting cranes, that's where they are.

But the more useful number for a buyer is supply relative to what's already there, and that story has moved to the middle ring. In Coburg, Ringwood, Hampton East and Port Melbourne, the committed pipeline is large enough to lift the local apartment stock by more than the number of apartments standing today (149%, 117%, 136% and 117% respectively) — all genuine, reasonably-sized existing markets (1,000+ apartments each), not small-base artifacts. That's a materially different situation to an established suburb like St Kilda or Prahran, where a similar-looking absolute number of new apartments (723 and 334) barely moves the needle against a much larger existing base (9,057 and 4,034).

For a buyer or investor, a lot of new stock landing in a small-to-medium existing market is the classic setup for softer rents and slower capital growth while it's absorbed. It cuts both ways — heavy supply also means more choice and often sharper prices for buyers shopping right now. The point isn't that a big pipeline is inherently bad; it's that you should know it's coming before you commit to a specific building or block. Each suburb's Delora profile breaks its development pipeline down by project stage (under construction, firm, proposed).

Reading the extreme percentages correctly

A handful of suburbs — Ringwood East (919%), Spotswood (827%), Mulgrave (802%), Narre Warren (181%), Sunshine (173%) — show enormous percentage figures that look alarming at first glance. In every one of these cases, the existing apartment stock is small (all under 310 apartments, several under 50), so a modest, genuinely real pipeline of a few hundred apartments produces a huge percentage change. Mulgrave's headline "802%" is 171 new apartments against an estimated 21 existing — worth knowing, but a different kind of risk to Coburg's 1,643 new apartments landing on an existing base of 1,105. Always read the raw committed count next to the percentage, not the percentage alone.

Frequently asked questions

Does a big apartment pipeline lower prices?
Not always, but a large amount of new supply relative to the existing stock tends to cap capital growth and soften rents while it's absorbed. It's one signal among several — demand, location and dwelling quality all matter too — but it's worth knowing before you buy an apartment or invest in one.

Which Melbourne suburbs have the most apartments being built?
By raw count, Docklands leads with 7,365 apartments under construction or firmly committed, followed by the City of Melbourne (6,411) and Southbank (5,133). Relative to existing stock, Coburg, Ringwood, Hampton East and Port Melbourne stand out — all with pipelines large enough to more than double their current apartment count.

What counts as "committed" in the pipeline?
Apartments recorded as Under Construction or Firm in the Victorian Government's Urban Development Program (UDP, mrs2025). This tracks major projects specifically, so smaller infill developments (a handful of townhouses or a small boutique block) generally aren't captured.

Why do some suburbs show percentages over 100%, or even over 500%?
Because "existing apartment stock" is estimated from a small base in some suburbs. Where the existing stock is genuinely small (under a few hundred apartments), even a modest, real pipeline can look like an enormous percentage increase. Check the raw committed-apartment count alongside the percentage — it tells you whether you're looking at a small market absorbing a real but modest amount of new supply, or a large market being fundamentally reshaped.

Is a big apartment pipeline always a bad sign for buyers?
No. It typically means softer rents and slower capital growth for existing apartments in that suburb while the new supply is absorbed, but it also means more choice, often sharper prices on new stock, and generally reflects a suburb with strong underlying demand (developers don't build where nobody wants to live). Treat it as one input, not a verdict.
