Security system installation & repair

Security system installation and repair in Australia

Updated 31 October 2026

A security alarm installed in Australia usually costs between A$500 and A$2,200, depending on whether it is wired or wireless and whether it is monitored. A home CCTV system in Sydney typically costs A$800 to A$3,500. For a price for your own home, describe the system you need on BlaBlaPrice and compare offers from local installers.

Licences: who may install a system

Licensing for security work varies by state and territory. In Western Australia, anyone who installs, repairs or maintains security alarm systems or locks for pay must hold a security licence. The applicant must be at least 18 and hold evidence of a required training course, and a one-year licence costs about A$1,141 according to one licensing guide. In Queensland you need a current licence to do this job. Installing cameras for pay can also need a Class 2C licence, according to one guide. Ask any installer for the licence number and check that it covers the work you want.

Timing and the Australian climate

Installation is mostly indoors, so the weather matters less than the timing. Australia is in the southern hemisphere, where summer runs from December to February and winter from June to August, so October is spring. Cameras and sensors fixed outside face the summer heat and winter rain, so ask for equipment rated for outdoor use. Batteries need replacing as well: in the listings we found, a backup battery costs about A$26 and a power supply about A$30.

How installers quote and what to tell them

Security work is quoted per job, not per square metre. Ask whether the price includes the equipment, the labour and any monitoring set-up, since the figures above list these separately. Say how many doors, windows and cameras the site has, whether you want wired or wireless equipment, and whether you already have a system to repair or upgrade. Give the site address and suburb so an installer in your city can reply, and state your budget.

You can get offers for security work through BlaBlaPrice. Describe the home and the system you want in your own words in the chat, and add a photo if you have one. BlaBlaPrice's AI asks for any missing details, looks through local sellers' websites and price lists, and shows the prices and businesses it finds. Installers registered on BlaBlaPrice receive your request and reply in the chat with their own price and terms, while your contacts stay hidden until you decide to share them.
