For over a hundred years, Southern Cross have been designing and building water tanks Sunshine Coast residents can trust.
Due to many people in Queensland being mindful of their water harvesting and water storage needs, many still turn to a Southern Cross water tank to help meet their needs.

With a range of tank sizes from 26kL – 600kL in our rural tanks, and from 12kL – 1900kL in our commercial tanks (with sizes outside this range available on request) you can rest assured that we have the right size tank to suit your water storage needs.





Rain is a refreshing sight for most people across Queensland, but as a result of modernised conveniences like as roads and paving, large amounts of rain can bring about flash flooding, damaging homes and the ecosystem.
Attaching a roof gutter system and a rainwater tank can help reduce the amount of water building up from stormwater run-off, and decrease the likelihood of flash flooding.
Sadly the long hot summers in Sunshine Coast leave it, like much of Australia, susceptible to wide-spread bushfires. Despite the fact that much of Sunshine Coast’s rainfall comes in the warmer months, this often results in long grasses which ignite easily.
Typical of South East Queensland, Sunshine Coast sits in a humid subtropical climate zone, with warm humid summers, and more mild winters. The Sunshine Coast doesn’t have a dry season, so much as a wet season and a wetter season.
Southern Cross have been providing the finest quality steel bolted storage tanks to Australians for over 50 years, and all of our tanks have a 30 + year design life.
At Southern Cross, we specialise not only in the design and manufacture of world wide water storage systems, but also the installation and service life. We take pride in the integrity and design of our fire storage tanks.
The first Southern Cross windmill was manufactured in the Toowoomba Foundry in 1903, and not far behind was the first Southern Cross water tank, meaning nobody knows the extraordinary storage needs of Sunshine Coast and Australia like we do.
When the Griffiths family created the Southern Cross brand out of the Toowoomba Foundry, they almost certainly didn’t know that it would continue on to become such an iconic Australian brand, still in operation over a century later.
In 2015, a water storage tank at the Sunshine Coast University Hospital suffered a structiral failure, causing the tank to flood the nearby Kawana Way with approximately two and a half million litres of water, washing away a family vehicle and causing destruction to the surroundings.
In the early 1800’s, three former convicts lived with the Kabi Kabi first nations people for eight months after becoming hopelessly lost while searching for cedar.
