The first land sales in the area occurred in 1857. Land sales around the Bald Hills railway station were advertised in April 1886. At the time the journey from Brisbane was described as "after travelling across the Downfall and Cabbage Tree Creeks, the traveller arrives at a long stretch of road, at the extremity of which rises a lofty knoll, round the brow of which the road winds, when the Bald Hills are reached".

In 1888, the "Bald Hills Railway Station Estate" made up of 500 allotments was advertised to be auctioned by Arthur Martin & Co., auctioneers. A map advertising the auction indicates that the land is situated near Bald Hills railway station and special trains will be provided on the day of the sale.
