We find the cabling, Wi-Fi and in-building 4G/5G faults your monitoring can't see, fix them on live networks, and hand you the test results and as-builts. Sydney-based, delivered nationally. ARC licensed. AS/CA S009 on every install.
Free review: target same day. Technician visit: up to 90 minutes on site with written findings, A$495 ex GST.
Trusted Partners & Vendors






















Five free tools. No sales call. Each one asks for a work email and gives you something you can use.
Fixed-scope work with the price on the page. Anything beyond the scope is quoted and approved by you first.

Also fixed-scope: Fix Now, Improve Later (A$495), Go-Live Assistance (A$750 to A$1,500), One Branch First (A$1,800 to A$3,500) and Your Field Team (quoted to scope, for IT providers). All prices ex GST.
Every AI rollout, cloud migration and SD-WAN deployment runs on cables, patch panels and connections that were installed years ago and never retested under today's load. The stack gets smarter. The copper doesn't care. When the physical layer fails, everything above it fails too, and your monitoring can't tell you why.
We work on live, business-critical networks. Every job ends with test results and as-built documentation you can hand to the next engineer. One partner, nationwide.
We work where a connectivity failure means a patient-safety risk, a stopped production line or a store that can't take payments. That includes live clinical environments.



"They are competitively priced and are very well staffed, with many jobs attended to on the same day or next day."
"The work was completed on time within budget and most importantly they minimized the [disruption] to the working of the office while doing the work as it had to be done during business hours."
"I have worked with David and the team at AAA Communications for many years now and the experience has been nothing short of outstanding. ... Their proactive and flexible approach has made a huge difference in keeping our major IT projects on track and within budget."

A Layer 1 audit tests your copper and fibre, checks racks, pathways and labelling against AS/CA S009, and gives you a remediation plan ranked by operational risk. Done on the live network.
David Barrett posts what breaks networks and how we found it, every Tuesday, Thursday and Saturday.
Common Questions
Straight answers on how we work, what we test, and what to expect.
Nothing, if you start with a free tool. Rate My Rack reviews your network cabinet from 3 photos, with a target of same day. If you want a technician on site, Find the Fault is A$495 ex GST for up to 90 minutes, with written findings and prioritised next steps. Larger work is quoted to a fixed scope, and nothing extra happens without your approval.
Layer 1 is the physical foundation of your network: the structured cabling, fibre links, patch panels, connectors, and physical pathways that every device, application, and cloud service runs on. Wi-Fi, VoIP, clinical systems, cloud applications, and SD-WAN all depend on Layer 1 performing correctly under real operational load. It is the layer most organisations stop validating once it is installed. That is where risk accumulates. When Layer 1 fails or degrades, every layer above it fails with it. And the intelligent systems built on top cannot tell you why. Validating and documenting the physical layer before problems surface is the work AAA Communications has been doing since 1992.
You can't tell by looking. In our testing of brownfield sites, between 20 and 40 percent of links have a fault that visual inspection misses. If you have intermittent dropouts, slow throughput after a switch or access point upgrade, or performance that gets worse under load, test the cabling first. A certified test, OTDR for fibre and TSB-155 swept frequency for copper, shows what the eye can't. We isolate faults on live networks without disrupting operations. Not ready for a site visit? The free dropout quiz gives you a next-test plan in about 3 minutes.
A Layer 1 audit is a standards-aligned assessment of your physical infrastructure: copper cabling, fibre, patch panels, racks, pathways, and labelling. We test to AS/CA S009 and international cabling standards, identify every fault and compliance gap, and produce an actionable remediation plan with issues prioritised by operational risk. The audit covers certification testing, OTDR trace analysis, physical plant documentation, and as-built reconciliation. The output is evidence you can act on, not a sales pitch for new hardware.
Yes. Live network delivery is a core part of how AAA Communications operates. We work on hospital clinical networks, active production floors, retail environments during trade, and enterprise campuses with no tolerance for downtime. Every engagement is planned and executed to avoid disruption. We have been doing this since 1992, including 34 years as a Telstra Partner delivering on live infrastructure.
Certification confirms a cable passed a standards test at the time of installation. It does not confirm the cable will perform under the load your current network places on it. Every Wi-Fi 6 rollout, SD-WAN deployment, and PoE++ device adds demand the original cabling was never tested against. Marginal faults that cheaper switches tolerate surface immediately when enterprise-grade hardware arrives. We test infrastructure under real operational conditions, not the conditions that existed when the cable was first certified.
Yes. Our in-building cellular service covers all Australian carriers: Telstra, Optus, and TPG/Vodafone. We design, install, and validate CEL-FI smart repeater systems and Nextivity Quatra DAS solutions for hospitals, industrial facilities, warehouses, and high-density commercial environments. Coverage is validated post-installation with signal measurements across every zone. The same team that designs the solution delivers and validates it. No third-party handoffs.
Health, industrial, retail, and corporate: environments where a connectivity failure has real operational, safety, or compliance consequences. We work across NSW Health facilities and private hospitals, manufacturing and warehouse environments, national retail chains, and enterprise campuses. Where uptime is not optional, the physical layer needs to be validated to match.
Sydney-based, nationally delivered. AAA Communications operates as a single accountable partner across Australia: one team, one point of contact, consistent standards regardless of site location. Recent jobs include Sydney, Wollongong, Melbourne, Dandenong and regional Perth.
Pick the starting point that suits you: a free tool, a fixed-price technician visit from A$495 ex GST, or a conversation about a larger project. From there most work follows the same four steps: an audit or survey to establish what is there, a findings report with prioritised fixes, scoped delivery of the fix, and as-built documentation at the end. One partner for all four. No handoffs.
Target: same day. One cabinet per business. Work email required. Need someone on site instead? A technician visit is A$495 ex GST.
