Internship Program 

In March 2019, GPSA called for expressions of interest from undergraduate students enrolled in a tertiary agricultural science degree to join the Secretariat as an intern. This provides an opportunity for students to develop new professional skills, build industry networks and undertake paid work experience while completing their study.

During the term of internship, GPSA extended a range of professional development opportunities, including mentoring from industry leaders as well as the chance to attend committee meetings, field days, and other industry events throughout the year. The program was developed in consultation with the University of Adelaide to meet the course requirements of formal work experience to qualify for graduation.
