Our Story

Previously known as TJM Electrical & Solar, we grew up and live in Moreton Bay Region and realise exceptional service, good quality parts and superior workmanship is how we can best service our customers and ensure we are in business long-term

Moreton Bay Region Electrical Services

Based in Wamuran, Moreton Bay Region, Mern Industries was established in 2009 as TJM Electrical & Solar. Rebranding in 2021 to Mern Industries, this change more appropriately reflected the business’s growth and expansion to the variety of services we provide, along with it being part of our family name.

The business is still owned and directed by Tony with his wife Amanda who have a long history in the local community. They felt there was a need in the local community to access quality electrical, air conditioning and solar solutions for current residents and farmers as well as new families moving to the area.

They wanted to make people’s day-to-day living and working lives more comfortable and easier while giving a personalised, quality, value for money service.

What we do best

Tony has extensive experience in all aspects of electrical installations, air conditioning, telecommunications and fault finding. He is also a fully accredited solar designer and installer for grid connect solar, and solar system with battery back-up and has been installing solar since 2009.

Tony’s experience and skill in sheet metal fabrication also complements our services with custom-designed and manufactured steel covers, boxes and cages for safety and weather protection of inverters, air conditioners and the like. All of which are made locally, here in Wamuran.

Mern were recommended to me by a friend. Matthew and Scott offered a professional, efficient and friendly service. They made a great team and helped me find a solution to a couple of issues. Wouldn’t hesitate to have them back or recommend them to others.

Sheryl Mann


Exceptional customer service both on the phone and when Tony arrived. Greeted with a hand shake and smile, he got straight to work and identified the issues quickly. He was clear with what was required and had it done very quickly as well as discussing further work. We will be sure to use them again.

Solar with Batteries installed – these guys were good to deal with from start to finish. I cant knock anything they did and they have been great to deal with in the 2 months since completion. I couldn’t recommend them highly enough.

Peter Lee


I personally use Mern for my electrical needs at home as well as our organisation Enhance Care uses them for all electrical repairs and installations at Caboolture Memorial Hall, Donnybrook Community Hall and Wamuran Sports Complex Hall.

Tony and the team are very very responsive and always fix any issues we have with total professionalism and everyone is so courteous. The girls in the office are excellent and go out of their way to help.

I would highly recommend Mern if you are looking for a quality service at a reasonable price.

Tony and his Boys (Matt and Scott) are the most professional electrical team you could ever get for your home or business. I have used their services extensively for both my business and home for general repairs and install through to solving complex IT cabling problems and major electricity power box upgrades. The admin team of Amanda and Jade have amazing customer service and are invaluable when liaison with Energex etc is required. I will go no where else for my electrical needs.

From beginning to getting a quote and the installation of solar the service could not be faulted. Tony and his team were considerate and professional, nothing was too much trouble and they worked with us to get the job done. We would recommend Mern Industries to everyone. Thanks for all your great work!

Trish Dellaway


Very friendly and professional. No issue was an issue! I had a few questions and Tony listened and gave a resolution straight away. Provided honest genuine feedback. After getting screwed over by another company it was a relief to have these guys at my home. I’m kicking myself for not using them in the first place. Which is why they’re back to do more work for me. Excellent quality and value. Refreshing really!

Katrina Gould


We were more than happy with the service and we will be definitely using you again. We will 200% be recommending you to family and friends

Greg Oliffe


TJM Electrical & Solar replaced my solar panels and inverter following the failure of my original equipment. They were competitive in their quotes and offered a selection of high quality equipment from which to choose. Office support and service was excellent. Installation was fast, and conducted very efficiently. The installation team members were friendly and informative. Their advice on safety was relevant and clear. This firm sets a standard for which most should aspire.
