He fought again in the Ottoman–Venetian War (1714–1718), under the command of Prince Eugene of Savoy at the Battle of Petrovaradin on 5 August 1716 and at the sieges of Temesvár and Belgrade. The following year he was put in command of three regiments and posted to operations in Naples. In the War of the Quadruple Alliance (1718–20) he fought in the Austrian army on Sicily, being wounded in the struggle for Messina but later becoming governor of that city's fortress until 1727, when he returned to Austria. When the Anglo-Spanish War (1727–1729) threatened to escalate the Holy Roman Emperor ordered Olivier back to Sicily to ready the island's defences. When no attack on Sicily came Olivier was dismissed in 1731 and from then until 1734 commanded the fortress at Mainz. In the War of the Polish Succession (1733–1735/38) he served against France in northern Italy (from 1723 with the rank of Feldzeugmeister); he even took overall command of the whole Austrian force there for a time and won some advantages.
