G'day! Sick of your Wi-Fi dropping out in the middle of a Zoom call? Or the 4K Netflix stream turning into a pixelated, buffering mess just as you get to the good bit? It's a fair dinkum nightmare.

Wi-Fi is handy for wandering around with your phone, but for a rock-solid, high-speed connection, you just can't beat a proper hardwired data cable. And in 2025, the standard for any new Aussie install – the one any pro will tell you to use – is the Cat 6 cable.

So, What is a Cat 6 Cable, Exactly?

A Cat 6 cable (which stands for Category 6) is the modern, high-speed standard for Ethernet and data cabling in Australia. It's that cable (usually blue, grey, or yellow) that runs from your NBN modem to your computer, smart TV, or gaming console.

Inside, it has 8 little wires, twisted into 4 pairs, just like its older, slower cousin, Cat 5e. But the way it's built makes it a hell of a lot better.

Cat 6 vs. Cat 5e: Why It's a Ripper Upgrade

So, what's the big deal? Why not just use the old Cat 5e cable? It all comes down to speed and reliability, mate.

• It's Built Tougher: A Cat 6 cable is manufactured to a higher standard. It often has a thin plastic spline (a little "cross") running up the guts, which physically separates the 4 twisted pairs.
• Less 'Crosstalk' (Interference): This separation, plus the fact the wires are twisted more tightly, means there's way less interference (or "crosstalk") between the wires.
• More Grunt (Bandwidth): This is the big one. A Cat 6 cable is built for higher frequencies (250 MHz vs 100 MHz for Cat 5e).
• What This Means for You: It can handle way more data, simple as that. It's designed for Gigabit speeds (1000 Mbps) and can even handle lightning-fast 10 Gigabit speeds over shorter runs. Cat 5e really starts to struggle at those speeds.

The bottom line: For any new build or reno, you'd be a proper galah not to use Cat 6 cable. It's the new minimum and properly future-proofs your home for faster NBN plans to come.

Where You'd Use It

• Hardwiring your smart TV or gaming console (PS5/Xbox) for lag-free streaming and gaming.
• Running a new data point to your home office PC for rock-solid video calls.
• Connecting your NBN modem to your Wi-Fi router for the best possible starting speed.
• Any new home data installation, full stop.

The CRITICAL Safety & Compliance Warning: DIY vs. Pro

Righto, let's get dead serious for a sec, because this is the most important part of the whole article.

• DIY (Go for it, mate!): Buying a pre-made Cat 6 cable (a 'patch lead') from a shop to run outside your walls from the socket to your computer? Go for your life. Too easy.
• PRO ONLY (Stop!): Want to install a new data point? This involves running the solid-core Cat 6 cable inside your walls, floor, or ceiling and terminating it at a wall plate.

In Australia, this is strictly not a DIY job. Any fixed data, communications, or telephone cabling must be installed by a licensed cabler (registered with ACMA).

Why? It's the law, mate. A dodgy data install (especially with cheap cable from a non-specialist supplier) can create interference (messing up your and your neighbour's NBN). Worse, if it's run too close to 240V power wiring without proper separation, it can become a serious electrical hazard.

A Professional Job Needs Professional Gear

A licensed cabler or licensed electrician knows that a rock-solid, high-speed network relies on high-quality, compliant components from end to end. They can't risk a job on cheap, dodgy cable that will fail in a year. This is why they source their gear from a trusted electrical wholesaler.

As one of Australia's most comprehensive electrical wholesaler and supplier networks, Schnap Electric Products stocks the lot for the professional installer. They've got massive rolls of high-quality, trade-grade Cat 6 cable, alongside all the compliant RJ45 plugs, wall jacks, patch panels, and specialist crimping and testing tools that a qualified professional needs to do the job right. For a connection that won't let you down, the pros start with quality gear from a supplier like Schnap Electric.
