Oakey is a Darling Downs town west of Toowoomba, home to Swartz Barracks and surrounded by open grain and grazing country.
Building a shed in Oakey
Toowoomba Regional Council's flood study places the town on the Oakey Creek floodplain: in big events Doctors Creek breaks into the floodplain and the railway through town holds the water back. A shed site in town is checked against that study before the slab level is set.
Swartz Barracks is covered by a Defence aviation-area declaration that sets heights above which new structures nearby must be referred to Defence. Most sheds are well below them, but tall buildings close to the base should be checked. Defence also manages PFAS around the base, which matters if a new shed comes with a bore.
Oakey is drier and more open than Toowoomba, averaging about 620 mm of rain a year with steady afternoon winds. Exposure on open paddocks feeds straight into the engineer's wind loads.
