The region is bigger than the city
The Bundaberg Region council area runs from Bargara and Burnett Heads on the coast to Gin Gin in the west and Childers in the south, with about 99,000 residents against roughly 74,000 in the urban area at the 2021 Census. If you drive to Childers, the campaign targets Childers. If you do not, it excludes it, and the landing page says so.
