Each year, the Greek Ministry of Culture issues six permits for Austrian fieldwork in Greece. Three of these are national excavation licenses, while the other three are granted for Greek-Austrian collaborative projects.

The ongoing and recently completed excavation projects of the OeAI are located in the northern and western Peloponnese. They focus on the settlement history of Lousoi in the mountains of Arcadia and on the diachronic investigation of the settlement site of Aigeira on the Corinthian Gulf. At Kleidi-Samikon on the western coast of the Peloponnese, the regionally important sanctuary of Poseidon is located at a strategically significant site, where excavations have been conducted since 2022 in cooperation with the Ephorate of Antiquities of Elis. In 2020, a geophysical survey was conducted at Kontopigado, near Athens.

In addition, the OeAI Athens organises excavation permits for projects conducted by Austrian universities. These include, among others, the Aegina Project of the University of Salzburg and the excavations at Pheneos, carried out by the University of Graz in cooperation with the Ephorate of Corinthia between 2011 and 2015. From 2023 to 2025, excavations have been taking place at Leonidio-Plaka, ancient Prasiai, conducted by the University of Graz in collaboration with the Ephorate of Arcadia.
