Understanding intercom installation costs in Australia

What an intercom install costs in 2026

For a standard Australian home, a wired video intercom with one entry panel and one or two indoor monitors typically lands between $900 and $2,200 supplied and installed. Audio only systems sit lower, roughly $550 to $1,200, because the panel and the handsets are far simpler devices. At the other end, a system with multiple entry points, several monitors and integration into a gate and garage door commonly reaches $3,000 to $6,500. Apartment blocks are priced differently again, on a per apartment basis, and a small block of eight to twelve units generally runs $500 to $900 per apartment for the handset and fit off, plus a shared head end and entry panel cost of $2,000 to $5,000 that gets spread across the building.

Audio, video or app connected

The choice between audio and video is largely a security choice rather than a convenience one. Audio only tells you someone is there, video tells you who. In a household where deliveries and unfamiliar tradespeople are routine, the ability to see the doorstep before opening is the entire point of the system, and video has become the default specification on new work. App connected systems go one step further and push the door call to a phone, which means you can answer the gate from work or hold a delivery. That is genuinely useful, but it introduces a dependency on your internet connection and often on a vendor subscription, and it means the manufacturer can change or end support for the app during the life of the hardware. A wired system with a physical monitor will still work in ten years whether or not the company still exists.

Stations, entries and how the price actually scales

The two numbers that drive an intercom quote are how many indoor stations and how many entry panels you need. Indoor stations are the cheaper of the two, typically $300 to $600 each installed for a standard monitor, because each one is a device on a cable run that already exists. Entry panels are dearer, generally $700 to $1,500 each installed, since every one is an outdoor weatherproof unit with its own cable run, its own mounting and often its own power feed. This is why a house that wants the front door, the side gate and the garage all answerable costs so much more than a house with a single front entry, and it is worth asking honestly whether the side gate is a panel you will use or a line item you will regret.

Cabling, walls and the hidden labour

Most of the labour variance in an intercom job is in getting cable from the entry to the monitors. A single storey home with an accessible roof space or subfloor is straightforward, and a good installer will pull the cable in a few hours. Double brick construction, rendered walls, a slab on ground with no subfloor access, or a finished second storey with no ceiling void are all situations where the cable has to be chased into the wall or run in surface conduit. Chasing means cutting, patching and repainting, and the patching is very frequently excluded from the electrician's quote, so clarify who is responsible for making good. Where cable simply cannot be run, a wireless system is the fallback, but at a front gate 30 metres from the router, behind masonry, expect dropped calls and plan on charging a battery panel a few times a year.

Registered cabling and compliance

Fixed cabling work in Australia is regulated. Cabling that connects to the telecommunications network, and structured cabling generally, must be carried out or supervised by a registered cabler holding an ACMA recognised registration, and the work has to comply with the relevant wiring rules. Ask any installer for their cabler registration number rather than assuming an electrical licence covers it. Access control adds another compliance layer. Once an intercom releases an electric strike or a magnetic lock, the way that lock behaves in a power failure or a fire alarm becomes a life safety question, and in shared residential and commercial buildings the release generally has to be interfaced so that nobody is trapped inside. A cheap online kit wired in by a general handyman is precisely the scenario that fails an inspection.

Strata and small apartment blocks

Intercom replacement in a strata building is one of the more common capital works items a committee faces, because the systems installed through the 1990s and 2000s are now well past their supported life and spare handsets are unobtainable. The practical decision is whether to reuse the existing riser cabling, which can cut the project cost substantially, or to run new. Many modern two wire systems are designed for exactly this retrofit case. Get the quote to separate the shared head end and entry panel from the per apartment fit off, because that split determines how the cost is levied and makes it far easier to replace a single failed handset in year six without renegotiating a building wide contract.

Choosing an installer and what to confirm

Get at least three quotes and make sure each is pricing the same station and panel count, the same cabling approach and the same access control scope, since those three variables explain almost all of the spread. Confirm the brand and model rather than accepting a generic description, because parts availability in five years is the real long term cost. Check whether wall patching and painting are included, whether the app requires a subscription, and what the warranty covers on the outdoor panel specifically, since that is the component that lives in the weather and fails first. Use the estimator here to set a realistic bracket, then let the written quotes narrow it.
