Ronit bio image

Ronit Gabriel
Public Engagement Officer

Originally from Israel, with a keen interest in diplomacy and international politics, Ronit spent many years in France holding different positions at the Israeli Embassy in Paris. After finishing her MA studies in Political Science at the Tel Aviv University and a BA in International Relations and French Literature from the Hebrew University of Jerusalem, working for the Israeli foreign service was a very natural choice.

Ronit served as a policy advisor at the Permanent Delegation of Israel to the OECD and as a defence cooperation coordinator at the Defence mission in Paris. These positions gave her valuable experience advancing Israel׳s interests internationally.  In 2019 Ronit moved to Australia to take the role of cultural and academic advisor at the Israeli Embassy in Canberra, an excellent opportunity to get to know the richness and diversity of Australian society and heritage.

After completing her term at the Embassy, Ronit joined the ECAJ team as the Public Engagement Officer in Canberra. She is looking forward to continue working for the benefit of the Australian Jewish Community and promoting its interests and values.

Day-to-day, the ECAJ works on:

  • Protecting our religious freedoms to observe and practise Judaism in Australia;
  • Acquiring government funding for the Jewish community’s security needs;
  • Monitoring and reporting incidents of antisemitism;
  • Securing compensation for Holocaust survivors;
  • Advocating for the national rights of the Jewish people and encouraging support for Zionism in Australia;
  • Liaising with the Federal government to stamp out child abuse;
  • Monitoring the content of school curricula in teaching about Israel and the Holocaust;
  • Supporting initiatives to commemorate the Shoah; remembering our wonderful Jewish ANZACs; and
  • Providing support for the smaller Jewish communities outside of Sydney and Melbourne.
