CSU has Forensic Biotech, which you can do as a stand alone undergrad degree, or as a double with MedSc
So when I finish, depending on if I specialise, I'll have BMedSc(Path)/BForensicBiotech
Jobs are fairly limited, but if you're doing Biotech you're going to forcus on the DNA side of things. I do one crime scene subject (just finishing now) and we don't do any scene collection methods or techniques, we just learn about methods. Then in 3rd and 4th year we do DNA techniques and human molecular genetics, that sort of stuff.
If you want to do more hands on field work, I'd probably suggest a BAppliedSc
