Bailup is located on Toodyay Road, north east of Noble Falls in the Shire of Mundaring. Although not well known, from 1840 to 1861, it was home to a police station and the Wayside Inn.
The Police Station was a cluster of mud-brick buildings on the west side of the road. The inn had several licences but in 1861, the licence lapsed and the sly grog trade began. This did not last long as the last person dispensing the sly grog was charged with theft and incarcerated.
