Speaking Gamilaraay is taught at the University of Sydney, as it has been since 2006 [https://www.sydney.edu.au/units/INDG2005]. If you have questions about the Sydney course contact Tracey Cameron [tracey.cameron@sydney.edu.au].
It is also taught at the Australian National University, where it can be done facetoface and online by ANU students [https://programsandcourses.anu.edu.au/2020/course/INDG2003] and also through Open Universities Australia [https://www.open.edu.au/subjects/australian-national-university-speaking-gamilaraay-1-anu-indg2003].
When there are sufficient enrolments ANU also offers Gamilaraay2 as an intensive winter course.
For more about the ANU course contact John Giacon [john.giacon@anu.edu.au].
