Planning an intercom installation? In Australia, the cost of installation of intercom systems typically ranges from about $700 to $2,800 AUD per system for supply and install, depending on whether you choose audio, video intercom installation, or a setup with gate or lock release. This guide helps you compare intercom system installation options and understand what an intercom installer may charge based on the job type.

## Intercom Installation price breakdown

| Type | Cost per system (Existing cable in place) | Typical 1 system (Existing cable in place) job |
| --- | --- | --- |
| Audio intercom | $700 | $700 |
| Video intercom | $1,600 | $1,600 |
| Video plus gate / lock release | $2,800 | $2,800 |

## What affects Intercom Installation cost

- **Type of intercom system:** The biggest cost factor is the system you choose. A basic audio intercom starts at $700 per system, while a video intercom is $1,600 and a video plus gate or lock release setup is $2,800 where existing cable is already in place.
- **Existing cable vs new cable run:** If existing cable is in place, standard rates apply. If the installation of intercom wiring needs a new cable run, the cost is multiplied by 1.3, which increases the total supply and install price.
- **Site complexity:** More difficult jobs such as brick walls, two-storey homes, or long cable runs use a 1.5 multiplier. This can make intercom installation noticeably more expensive than a straightforward replacement or upgrade.
- **Number of systems:** This calculator is priced per system, so total cost rises with each additional unit installed. For a typical example of 1 system, you can use the listed per-system rates as the starting point before any site multipliers are applied.

## Frequently asked questions

### How much does intercom installation cost in Australia?

For 1 system with existing cable in place, supply and install pricing starts at $700 AUD for an audio intercom, $1,600 AUD for a video intercom, and $2,800 AUD for a video plus gate or lock release system. The displayed estimate range is usually shown at plus or minus 20% around the midpoint. A minimum job charge of $450 AUD applies if the calculated amount falls below that.

### What does the installation of intercom cost for a basic audio system?

A basic two-wire audio intercom at one door costs $700 AUD per system where existing cable is already in place. If the job needs a new cable run, that price is multiplied by 1.3. If the site is more complex, such as brick or two-storey access, a 1.5 multiplier applies instead.

### How much is video intercom installation?

Video intercom installation costs $1,600 AUD per system with existing cable in place. This covers supply and install of a video intercom with one outdoor camera station and one indoor monitor. If new cable is needed, multiply by 1.3, and for brick, two-storey or long-run jobs, multiply by 1.5.

### What is the cost of video intercom system installation with gate or lock release?

Video intercom system installation with gate or electric door strike release costs $2,800 AUD per system where existing cable is in place. This includes the video intercom wired to a gate or electric strike, plus the indoor monitor. More difficult installation conditions can increase the price using the 1.3 or 1.5 multipliers.

### How does an intercom installer price jobs with new cable runs?

An intercom installer applies the new cable run multiplier of 1.3 to the base per-system rate. For example, an audio intercom priced at $700 AUD with existing cable would be higher when a new cable run is required, and the same multiplier applies to the $1,600 AUD video and $2,800 AUD video plus gate or lock release options.

### What affects the price of intercom system installation the most?

The main factors are the type of system, whether existing cable is in place, and how difficult the site is to wire. A standard audio intercom starts at $700 AUD, while video intercom installation is $1,600 AUD and more advanced video plus gate or lock release setups are $2,800 AUD per system before multipliers. Brick walls, two-storey layouts and long cable runs increase the price with a 1.5 multiplier.
