Toowoomba locals have found a way to beat the heat as the first Queensland town to host giant water slide The City Slider when it slips into the region on Saturday.

The giant 325 metre water slide has already toured Tasmania and after Toowoomba will also make stops at Wollongong, Newcastle and Adelaide.

The super-slide will close off Margaret Street and will run from 10am to 10pm with four thousand participants expected to take the plunge and a further three thousand spectators to join in with the day's events.

The man responsible for bringing the quirky idea to life, The City Slider Co-Founder Stuart Harris said inspiration came from the United States, the land of all things big.
