Understanding intercom gate costs in Australia

What a gate intercom costs in 2026

A gate intercom supplied and installed in Australia in 2026 generally runs $1,200 to $6,000. A basic audio-only station with a single indoor handset and existing conduit is $800 to $1,800. The common case, a colour video station with one indoor monitor and a gate release relay, sits at $2,000 to $3,500. Add smartphone integration, multiple monitors, a vandal-resistant stainless faceplate and a pedestal mount, and you are at $3,500 to $6,000. Large properties needing a long cable run, or multi-dwelling installations with several handsets, move above that. The hardware is often less than half the total, with cabling and labour making up the rest.

Audio, video, app or 4G

Audio-only stations are cheap and reliable and still make sense on rural gates where you mainly need to talk to a delivery driver. Video is now the default in suburban installs because seeing who is at the gate is most of the point. App-based systems push the call to your phone so you can answer and open the gate from anywhere, which is genuinely useful for tradespeople and deliveries, but they depend on the manufacturer's cloud service continuing to exist. The safest configuration keeps a wired local monitor working independently of the app. 4G and SIM-based intercoms skip cabling to the house entirely and call your mobile directly, which is the practical answer on long rural driveways, at the cost of a monthly SIM plan and a dependence on mobile coverage at the gate.

Cabling is the real cost

The hardware is predictable. The cable run is not. If there is existing conduit from the house to the gate, installation is a few hours. If there is not, someone has to trench, lay conduit and pull cable, and at $60 to $120 a metre for trenching through established landscaping or under a driveway, a 60 metre run can add $2,000 or more. The critical detail is separation. Mains cable feeding the gate motor must not share a conduit with unshielded intercom audio or video cable, because the induced hum and picture noise is difficult to remedy once everything is buried. Run two conduits, always, and leave a draw wire in the spare.

Getting the mounting position right

The most common regret in gate intercoms is not the hardware, it is the height and position of the station. A unit bolted to the gate post at pedestrian height forces every driver to open the door, unclip the seatbelt and lean out. A gooseneck or pedestal mount set back from the gate at driver window height costs $400 to $600 more and transforms how the system is actually used. Set it back far enough that a car can sit clear of the gate swing or slide path while the driver uses it. Add camera illumination or infrared, because a video station facing a dark driveway at night is close to useless without it.

Integrating with the gate and the house

An intercom earns its keep when it can also open the gate. That means a dry contact relay from the intercom into the gate controller, which is a $200 to $300 item at install and closer to $500 as a retrofit. Where a gate motor already exists, most controllers have a dedicated input for exactly this. Some systems can also trigger a second relay for a pedestrian gate strike or a garage door. If you are running an alarm or camera system as well, ask whether the intercom video can be viewed on the same app or recorder, because consolidating to one app instead of three is worth paying a little more for.

Weather, vandalism and durability

Gate stations live outdoors in full sun, rain and salt air, which is harsher duty than anything inside the house. Plastic faceplates chalk and crack, and cheap units fail at the button membrane and the microphone port first. A stainless or die-cast vandal-resistant faceplate at $300 to $400 more is worth it in coastal areas and on street-front gates. Check the ingress protection rating, look for a rain hood or recessed mounting, and confirm the unit is rated for the temperature range it will see, since a west-facing station in inland Australia can reach very high surface temperatures in summer.

Comparing quotes

Ask each quote to separate the station and faceplate, the indoor monitors or handsets, the mounting hardware, the cable type and length, any trenching and conduit, the gate release relay, commissioning and programming, and the warranty. Confirm whether trenching is included or listed as by others, because that is where most of the price variation hides. For 4G systems, ask for the ongoing SIM plan cost in writing and insist on a coverage test at the gate position, not at the house. For app systems, ask what happens to the local monitor if the cloud service is discontinued.
