^^^ unfortunately since I don't have a licence my only option as a woman is to catch public transport. I used to work at a rehab in Wellard and would gave to catch trains home from Kwinana station as late as 11pm some nights I always felt safe, not quite so much on the deserted Joondalup line with not a guard in sight. There were always security guards at the Kwinana station and on the trains however during peak times and just off peak times you very rarely see transit guards on the actual trains, so much for every train having at least two transit guards at all times
Lucky for me boxing is at the core of my personal training regime so I do have some form of defense. If worse comes to worse I could always clock an attacker with my brick of a handbag.
