Location
Moorabool is a rural locality 12km north-west of Geelong and about 65km south-west of Melbourne.

Description
Moorabool is flat pasture country, bordered by the fertile river valley. It is in this valley more than 30 years ago that the region's winemaking industry began its successful resurgence. The vineyard and winery, then known as Idyll and now Jindalee Estate, occupies one of the most picturesque locations overlooking the river valley.

History
The rich Moorabool River valley attracted Swiss immigrant vinedressers (experts in pruning, training and cultivating vines) to the area in the 1840s to 1850s and orchard growers. The Swiss - in this and other areas they settled around the district - helped make Geelong Victoria's largest wine-producing district by the early 1870s. But disaster struck when the vine root aphid phylloxera vastatrix spread through Victoria and the Government ordered the destruction of affected vines.

Moorabool was arguably at its busiest during the construction of the Geelong-Ballarat railway line when a temporary township to house workers was established. One of the largest projects was the building of a huge viaduct, up to 35 metres high, across the Moorabool River valley at the cost of one million pounds. It has nine basalt pillars and abutments with steel trusses and was opened in April 1862. The bridge is still used and is on the Register of the National Estate because of its significance.

'Craigton', located off Viaduct Road, is also on the register. It was erected in 1860 for the chief engineer responsible for supervising the building the viaduct. Moorabool railway station was built of basalt in 1862, one of a number of similarly styled stations on the Geelong-Ballarat line. It, too, is on the Register of the National Estate.
