The Sausal is a small mountain range in the southwestern parts of Austria's state Styria. It thrusts up from the northern banks of the Sulm valley, west of the district town of Leibnitz. Its highest point, the summit of the Demmerkogel, rises 671 m above the level of the Adriatic Sea. Large parts of the Sausal have a mediterranean-type microclimate. Together with the rich soil this is the basis of its extensive vineyards, which are the cornerstone of the local economy. Tourism flourishes as well.

The Sulm is a river in Southern Styria, Austria. It is 29.3 km (18.2 mi) long. Its drainage basin is 1,121 km2 (433 sq mi). Its two source rivers Schwarze and Weiße Sulm both originate at the eastern slopes of the Koralpe. It flows eastwards towards the Mur through the districts of Deutschlandsberg and Leibnitz. The Sulm valley runs from the Western Styrian hill ranges to the Eastern Styrian hills and lowlands.
