Locations in Melb, Aus?

[heylightiforgot]

Not sure if this is against the rules (apologies if so) but I was planning to ctb next week and need a location idea. I'm thinking overdose or drowning. The issue is I'm disabled and can't walk very far. Is there anywhere around Melbourne (beaches) etc I could get to by cab (likely at night) without arousing suspicion? I'm based in the general suburbs, not anywhere rural.
