Home Theatre Installation in Melbourne: What It Really Costs, and How to Get It Right the First Time

Most people’s first home theatre is a compromise. The TV goes where the power point already is. The speakers end up wherever the furniture allows. The subwoofer gets shoved into a corner because that’s the only place it fits. Six months later the room sounds boomy, the dialogue is impossible to hear over the soundtrack, and the whole thing gets used to watch the news.

It doesn’t have to go that way. A properly planned home cinema is one of the few upgrades that genuinely changes how you use your house — and in Melbourne, it costs a lot less than most people assume. This guide walks through real package tiers, how to match a system to your actual room, and the seven mistakes we’re called out to fix most often.

How Much Does a Home Theatre Cost in Melbourne?

Prices vary with room size, whether you’re pre-wiring during a build or retrofitting, and how far you push the audio. As a working guide, here’s where most Melbourne installations land:

Entry level — $2,500 to $4,500

A quality 5.1 surround setup around a large TV, with in-ceiling or bookshelf speakers, an AV receiver, and a subwoofer. Cabling concealed in the wall. This is the sweet spot for a living room or open-plan lounge where the theatre shares space with everyday life.

Mid range — $5,000 to $9,000

A 4K projector and screen, 5.1.2 or 7.1 speaker configuration with Dolby Atmos height channels, dedicated amplification, and proper acoustic placement. Usually a spare bedroom, rumpus, or a purpose-built media room. This is the most common brief we get.

Premium — $12,000 and up

Dedicated cinema room, laser projector, acoustically treated walls, tiered seating, motorised screen, integrated lighting and control. Every cable planned before a single sheet of plaster goes up.

The single biggest cost lever isn’t the gear — it’s the walls. If your home is still under construction or you’re mid-renovation, running cable now costs a fraction of what it costs later. That’s why our pre-wiring service is the cheapest money you’ll ever spend on a home cinema. Retrofitting the same cable run through finished plaster can add thousands.

Projector or TV? The Honest Answer

Everyone wants the projector. Not everyone should have one.

Choose a 4K projector if: you can control the light. A room with a single window you can black out, or no windows at all, will give you a 120-inch image that a TV simply cannot match at any price. Modern laser projectors have solved the old lamp-replacement headache and hold their brightness for years.

Choose a large TV if: the room is your main living area with big windows and daytime use. A bright OLED or QLED will beat a projector fighting Melbourne’s afternoon sun every single time. Pair it with a proper surround system and a clean TV wall mounting job — bracket flush to the wall, cables inside it, no visible boxes — and it will look better than most projector setups anyway.

If you’re chasing free-to-air and sport alongside your movies, make sure your signal is solid before you spend on the screen. A weak feed will look bad on a $20,000 display. Our team handles digital TV antenna installation and repair as part of the same visit — worth sorting up front rather than discovering the problem on grand final day.

Speaker Layout: Get This Right and Everything Else Follows

You can buy exceptional speakers and make them sound mediocre by putting them in the wrong place. Placement is free. Use it.

  • Centre channel: carries roughly 70% of dialogue. It must sit directly above or below the screen, aimed at ear height when you’re seated. Never inside a cabinet.
  • Front left and right: form an equilateral triangle with your main seat, angled inward about 22-30 degrees.
  • Surrounds: beside or slightly behind the seating, above ear level. Not pointed straight at your head.
  • Atmos height speakers: in-ceiling, forward and slightly behind the listening position. This is what makes rain sound like it’s above you rather than beside you.
  • Subwoofer: corners boost bass but make it muddy. A little way out from the wall, along the front plane, usually beats a corner. It’s worth spending twenty minutes moving it around.

7 Mistakes We Get Called Out to Fix

  1. Forgetting about seating distance. A 120-inch screen viewed from 2 metres away is uncomfortable, not immersive. Roughly 1.5x the screen width is a reliable starting point.
  2. Undersized cable in the wall. The cable you run today needs to carry the bandwidth of the gear you’ll buy in five years. Cheap HDMI in plaster is a false economy.
  3. No network planning. Streaming 4K HDR, a projector, and a games console on one tired router is how you get buffering mid-film. Sorting your network access points during the build gives every device a solid connection.
  4. Ignoring the room’s acoustics. Hard floors, bare plaster and glass make everything harsh and echoey. A rug, curtains and a bookshelf do more than a $2,000 amplifier upgrade.
  5. Skipping calibration. Speaker distances, levels and crossover points need to be set for your room. Out of the box, they’re set for nobody’s room.
  6. Not enough power outlets behind the AV rack. You will need more than you think. Plan for double.
  7. Treating security and AV as separate jobs. They share cable paths, network infrastructure and wall cavities. Running them together in one visit is cheaper and tidier than running them twice.

The Best Home Security Camera System in 2026: An Installer’s Honest Comparison

  The Best Home Security Camera System in 2026: An Installer’s Honest Comparison Every “best security camera” article you’ve read was written by someone who has never drilled a hole in a wall. They rank cameras by spec sheet. We install these systems in Melbourne homes every week, then get called back when something doesn’t work — which teaches you very different things about which cameras are actually good. This is a straight comparison of the four brands we install: Dahua , Hikvision , HiLook and Uniview . We stock all of them. We have no reason to push you toward one. First: The Thing Nobody Tells You The brand matters less than the install. A $2,000 camera system mounted at the wrong height, aimed at the wrong angle, with the recorder sitting in plain sight by the front door, is worse than an $800 system installed properly. The three things that actually determine whether your cameras identify an intruder: Height and angle. Cameras mounted too high see the top of a head. 2.5-3...

Do Melbourne Businesses Still Need a Commercial Alarm System in 2026? Monitored Alarms, CCTV Integration & Insurance Considerations

  Do Melbourne Businesses Still Need a Commercial Alarm System in 2026? Monitored Alarms, CCTV Integration & Insurance Considerations It’s a fair question. With cameras on every corner, smart locks, and phones that ping you the moment something moves, plenty of business owners wonder whether a traditional alarm still earns its keep. If the CCTV is already recording, why bother with sensors and sirens? The honest answer, after years of fitting security across Melbourne workplaces: cameras and alarms do different jobs, and for most businesses you want both. A camera tells you what happened. A commercial alarm system is what actually interrupts a break-in while it’s happening and, when it’s monitored, gets a response moving. This article looks at where alarms still matter in 2026, how monitoring and CCTV work together, and what your insurer is likely to expect. What a Commercial Alarm System Does That Cameras Don’t? There’s a common mix-up that CCTV and alarms are two ver...
