Is Aluminium Wiring in Your Wollongong Home Safe?

You may not realise it, but if you live in the Wollongong region, particularly in older suburbs like Thirroul, Figtree, or Corrimal, your property could contain outdated aluminium wiring. While there’s no need to panic, it’s worth being aware of the potential risks involved.

Aluminium wiring served its purpose decades ago, with the wiring commonly installed in Australian homes built during the 1960s and 1970s, when copper prices soared and builders sought a more affordable alternative. As such, it seemed like the perfect solution at the time: lightweight, inexpensive, and easy to work with. But more recently, it's been linked to electrical faults, overheating, and safety concerns.

Here's what you need to know.

Risks of Aluminium Wiring

Aluminium expands and contracts more than copper, meaning loose connections, overheating, and even electrical fires can happen.

Aluminium oxidises easily, forming a non-conductive layer that increases electrical resistance and heat at connection points. Over time, this can lead to overheating and potential fire hazards. In some cases, older aluminium wiring installations may also fall short of current Australian electrical standards if they’ve deteriorated or been altered incorrectly, which can complicate insurance claims. By contrast, copper wiring is more stable, conductive, and reliable, making it the preferred material for modern electrical systems.

Local Spotlight: Wollongong Homes

Based on our experience working in the Illawarra area for over 30 years, we’ve seen firsthand how common aluminium wiring still is in many Wollongong homes. As such, we're well-acquainted with the unique challenges it presents. This is especially true in older suburbs such as Woonona, Fairy Meadow, Unanderra, Figtree, and Corrimal, where many homes were built during the 1960s and ’70s boom when aluminium wiring was widely used. The combination of ageing connections, coastal corrosion, and inconsistent wiring standards keeps us busy removing electrical hazards and bringing homes up to today’s safety standards.

Signs Your Wollongong Home May Have Aluminium Wiring

Now you might be wondering whether your home has aluminium wiring, and thankfully, there are a few clues to look out for with your electrical system. Firstly, was your house built or renovated between the mid-1960s and late 1970s? If so, you're a likely candidate.

Here are the safety hazards to look for:

• Dull silver-coloured wiring behind outlets or switches (instead of the usual copper tone)
• 'Frequent circuit breaker trips
• Flickering lights (that aren’t tied to electrical appliances)
• Discoloured outlets
• Faint burning smell
• Electric shocks
• Evidence of DIY electrical work or faulty wiring
• Frequent circuit breaker trips
• Flickering lights (that aren’t tied to electrical appliances)
• Discoloured outlets
• Faint burning smell
• Electric shocks
• Evidence of DIY electrical work or faulty wiring

If you recognise any of the above, it's wise to book an inspection by a licensed Wollongong electrician.

What You Can Do About It

If it turns out that your Wollongong home has aluminium wiring, there are several solutions available, the most common being rewiring. This can either be a full rewire (safest) or a partial rewire, which just targets the high-risk areas like kitchens and switchboards.

If you really want to ensure the safety and compliance of your home's electrical system, then regular electrical safety inspections are essential. They catch early warning signs before they become serious.

But it's crucial to always work with a licensed Wollongong electrician familiar with local housing conditions, not some unlicensed cowboy undercutting the professionals. A fully qualified electrician will advise on the most cost-effective and compliant approach to avoid potential electrical hazards.

Risks of DIY Electrical Work

It might be tempting to tackle electrical projects yourself, especially with so many online tutorials. While the home renovation shows have made DIY more popular, electrical work is far more dangerous than typical home improvements. Unlike painting or basic carpentry, working with electricity carries an immediate risk of severe injury, electric shock, or even death. Even a minor mistake, like a loose connection or improper wire sizing, can create potential hazards such as short circuits, power surges, or fire.

Without the proper training, we've seen customers overlook issues like oxidation, worn insulation, or overloaded circuits. Furthermore, DIY electrical work is illegal in NSW and can also void your insurance policy.

In short, it's just not worth the risk.

Licensed electricians undergo years of training and apprenticeship to identify hidden risks, ensure connections meet current standards, and perform safe, compliant installations. By leaving electrical work to the professionals, you not only protect yourself and your family but also safeguard your home from long-term hazards that could cost thousands in repairs.

Aluminium Wiring and Australian Standards

When it comes to aluminium wiring, compliance with Australian safety standards can make all the difference between a safe home and a potential fire risk. You should know that aluminium wiring itself isn’t actually illegal, but it still often doesn’t meet modern electrical safety codes unless it’s been properly maintained or upgraded using approved methods.

The current standards recommend replacing or professionally assessing older wiring systems, especially if your electrical system is showing signs of wear. Additionally, if you’re planning renovations, it makes sense to include new electrical installations.

Get Your Home Inspected

If your home was built in the 60s or 70s, or you’ve noticed flickering lights or discoloured outlets, it’s worth getting your wiring checked. A professional inspection by a licensed Wollongong electrician will not only identify whether aluminium wiring poses any safety risks, but also recommend the best long-term, cost-effective solution.
