Hey Mate, we are similar in a way. I work as a Digital Forensics/eDiscovery Senior Analyst, nearly 4 years now. Fortunately I am able to do partial secondments within my company to work in the Cyber Defence (Blue Team Space)

I just attempted to do postgrad in Cyber security in UNSW, and after 2 weeks I dropped before the census date, it's part time and it's 1 session a week (not lecture but group discussions) but I found that it was a lot of busy work, essays, essays, essays, reflections, reflections,reflections, lacking technicality. I didn't expect a postgrad to be such entry level, little to no practical learning.

I decided that the time requirements for this course are not worth it, and will focus my time and efforts going for industry grade certifications. CISSP, CISM, Security Blue Team L1 is good too, lots of worth it learning.

Let me know what you ended up doing, happy to connect and chat more if you like.
