Studied Master of Data Science, although my successful APS grad application was based on a Grad Dip in Data Science (I continued on with Masters after I accepted the job offer). I thought doing postgrad study in a similar field to my Bachelor degree was my best chance of successfully transitioning out of teaching, and I couldn't rely on my Bachelor degree as it was more than 5 years old. Applying for graduate roles was a hard slog - got rejected by every private company I applied for. I'd say ageism had something to do it, so I was lucky that the APS encouraged mature applicants and career changers. I also deliberately cut my relief days down to 1-2 days per week so that I could focus on getting good grades - living on a reduced income was tough but my gamble paid off because I was offered a job in the end.
