The Caboolture River flows from north to east through the locality with Zillmans Crossing ( ) being a former ford (now a low-level bridge) across the river. The ford was part of the Old North Road (now superseded by the Bruce Highway) and was named after Leopold Zillman, an early pioneer farmer in the area. The river flats (elevation about 50 metres above sea level) are used for agriculture, mostly grazing, but the western side of the locality is undeveloped mountain land rising to numerous unnamed peaks, the highest being 350 metres above sea level.
There is a picnic reserve near Zillmans Crossing.
The locality takes its name from the property name used by the Zillman family. In the early 1840s, the Archer brothers of Durundur Station and Evan Mackenzie of Kilcoy Station blazed a trail to connect their farms with Brisbane, creating Old North Road (as it now known) as the first road north from Brisbane. Later it was supplanted by a road closer to the coast (now known as Old Gympie Road) and subsequently by the Bruce Highway even closer to the coast.
