Are you doing it at a college or at a place like tobin brothers cos i know they run the courses as well.. Did she give your the address cos if she is saying Noble park area.. it may even be up near princes hwy, which is near me and completely safe... just not super easy to get to by train. but I am close by so can give you a ride to the station whenever.
I was thinking the same thing (ie Noble Park "area" covers quite a bit!!)
