What Our Customers Say

I would just like to say that have the best service yet for something that was purchased outside of my local community, it all happened on time delivery was exactly when they said. I will be purchasing more tanks in the near future through National Poly Industries.

Graeme PieperBenair, Qld

I have purchased tanks from National Poly over the last ten years for my own residential properties. Never had any problems, good service and delivery and best price every time.

Robert SmithNingi, Qld

Over the Christmas period, when no one else wanted to do do business and we were desperate to get a tank, these guys were only too happy to oblige so that we would have water when we moved into our new home in the new year. Very impressed and thankful!

Wood BronwynCooran, Qld

We have now purchased 52 tanks of various sizes since 2007 with no problems at all with any. We have had excellent service, speedy delivery and great communication with all our purchases. No doubt we will be adding to this tally in the near future.
