Australian owned & Australian made.


Established in 2006, Australian Poly Tanks specialises in the manufacture of 5000 gallon poly water tanks.


As a family owned and operated company with combined experience of over 40 years in the manufacture of poly tanks and tank making machines, we take great pride in providing our customers a high-quality product and exceptional service every time.


The latest manufacturing technology, delivering outstanding design and great value.


Our 5000 gallon poly rainwater tanks are designed to suit the needs of rural and residential properties and are manufactured to the highest standards using premium, Australian UV stabilised food grade poly.


We use cutting-edge computer-operated machines and carefully crafted moulds to deliver a consistently high-quality tank, day after day. All tanks are ultrasound tested and visually inspected prior to delivery, so you can be assured you’re getting a great value product you can depend on.


Built strong for long-lasting performance.


All Australian Poly Tanks feature tapered walls, thickest at the base for added strength where it is needed most. Constructed in one piece, our seamless design provides a durable water storage solution, built to last and prevent leaking and corrosion.


Our tanks incorporate an extremely strong rib and domed roof, designed to eliminate the need for a pole and prevent the sag often seen with straight rib designs. 10-year warranty included on all Australian Poly Tanks.
