Cairns Electrical & Data Services
John attended on his day off before Christmas — and customers keep coming back because of moments like that.
That pre-arrival SMS, the prompt responses to inquiries by Sally-Ann, and the pattern of arriving early or on time across dozens of reviews suggests this is a deliberate business practice, not just good luck. For homeowners who've been burned by trades that ghost or reschedule, that reliability is probably the most decision-relevant thing to know. The data cabling side of the business (Antonio, Declan) is notably honest — two separate reviews describe technicians advising customers NOT to replace cabling that was still working, which is an uncommon stance worth noting if you're unsure whether a job actually needs doing. Pricing feedback across the sample skews toward 'fair' and 'reasonable', with one customer explicitly noting the final bill came in below the quote.

About Cairns Electrical & Data Services
John Goncalves leads the operation day-to-day and is the name customers mention most often — praised specifically for clear explanations of safety issues, arriving promptly, and treating small jobs (like a single damaged NBN socket) with the same care as large renovations. Sally-Ann handles the office side and gets credit for fast initial responses that set expectations before anyone shows up. On the tools, Antonio specialises in data and internet cabling work — including diagnosing NBN faults and honestly advising customers not to replace lines that are still functional — while Mitch, Declan, Jacob, and Murray round out a team that handles ceiling fans, switchboard assessments, security cameras, and full office electrical fitouts. The business covers both residential and commercial work, and several reviews confirm they travel to outer areas like Kuranda where finding reliable trades is genuinely difficult. Emergency callouts are a real strength here: multiple customers describe same-day or next-business-day responses to power failures and lightning strike damage, including a case where John attended on his day off just before Christmas. Cleanup is mentioned unprompted across many reviews — customers note technicians left homes and offices spotless — and the pricing feedback is consistently described as fair or cheaper than quoted, which is rare enough to be worth flagging.
Best for: same-day emergency power failures, data and NBN cabling faults, ceiling fan and lighting upgrades in residential homes, and electrical or data fitouts for small commercial offices.

Does Cairns Electrical & Data Services cover areas outside central Cairns?+
Yes — one review specifically mentions they travelled to Kuranda and the customer described finding a trade willing to make that trip as 'a revelation.' If you're in an outer suburb or regional area near Cairns, it's worth calling to confirm your address is in their range before booking. No reviews mention travel fees, so ask about that when you inquire.
Can they handle emergency electrical problems on short notice?+
Emergency response is one of the most frequently mentioned strengths in the reviews. Multiple customers describe same-day or next-business-day responses to power failures, including a lightning strike that knocked out an entire house's power supply. John personally attended one customer on his day off just before Christmas to restore internet for someone working from home. If you have an urgent situation, calling directly (rather than emailing) is likely to get the fastest response.
What do customers say about pricing?+
Pricing feedback across the 50 reviews we analysed is consistently described as 'fair,' 'reasonable,' or 'affordable' — and one customer noted their final bill came in below the original quote. No reviews mention unexpected charges or disputes over cost. For larger jobs, John typically provides a written quote upfront and customers report the process is clear and transparent.
Do they do data cabling and internet work, or just electrical?+
Both — the 'Data Services' part of their name is real. Antonio and Declan are the primary data cablers mentioned in reviews, handling NBN wall socket repairs, internet cabling faults, and signal testing. One review describes Antonio diagnosing an NBN issue, recognising it was a Telstra-side problem, and then calling a Telstra technician on the customer's behalf to arrange a priority visit. They also handle TV antenna connections.
How does the booking and communication process work?+
Sally-Ann manages the office and handles initial inquiries — customers describe her response time as fast. Once a job is booked, technicians send an SMS when they're approximately 10 minutes away, which multiple reviewers flagged as a standout detail compared to other trades. Quotes are sent digitally and can be accepted online. The team has been noted for showing up on the agreed date with all equipment already ordered and ready, avoiding the common problem of a first visit just to look and a second visit to actually do the work.
