2019 was the International Year of Indigenous Languages (IYIL2019), as declared by the United Nations General Assembly. The commemoration was used to raise awareness of and support for the preservation of Aboriginal languages within Australia, including spreading knowledge about the importance of each language to the identity and knowledge of Indigenous groups. Warrgamay/Girramay man Troy Wyles-Whelan joined the North Queensland Regional Aboriginal Corporation Language Centre (NQRACLC) in 2008, and has been contributing oral histories and the results of his own research to their database. As part of the efforts to raise awareness of Wiradjuri language a "Grammar of Wiradjuri language" was published in 2014 and "A new Wiradjuri dictionary" in 2010.
