What Our Clients Say

I am proud to supply this feedback as it has been a long time since I was treated so amazingly well as a customer until I dealt with Polymaster. A) received excellent Pre Sales & Service from your dealer, Martha at Electel. B) Then 10 days before delivery I received a positive call from a polite young lady who ran through the complete scope of the order. To say I was appreciative was an understatement. Wished more companies had your service commitment / DNA. C) Then a day before delivery I received a polite phone call from a truck driver who introduced himself as your driver and ran through the logistics / offloading etc. Said he couldn’t give me an exact time but would ring me in morning to advise exact ETA. I have never met a truck driver who was so organised. All of the above culminated in to me being blown away with Polymaster’s outstanding customer service. Thank you very much and please pass my feedback onto your Mgr Director. It was a pleasure to deal with a company who is so transparent and organised, congrats.

From entering details online and then talking with Tony Columbro to ensure I had details correct to then the text messages when the tank was ready. Then notified it was loaded and on its way to its new home. The whole process was professional and super smooth. Love the tank.

Great customer service especially Rachel. Also the driver was extremely helpful and professional in his handling of his job. Tank arrived on time as promised. The only little thing is that the tank was not put on position but close for us to push it the the foundation. Definitely we will order our next tank from them. Just recommended my friend to buy from Polymaster.

What makes our Australian-made tanks different?

  • Certified to Australian Standards: Our tanks are fully independently certified to strict AS/NZS 4766 standards for total wall-thickness and structural engineering integrity.

  • Built for Australian Solar Loads: We utilise a proprietary, food-grade, high-density polyethylene resin mixed with advanced UV-stabilisers. This formulation is explicitly engineered to prevent splitting, cracking, or fading under intense Australian sun exposure.

  • Seamless One-Piece Construction: Our rotational moulding technology creates a completely seamless tank body with no structural joints or welds—eliminating the common failure points found in cheaper, imported alternatives.
