I stand directly above the mouth of the Yarra River on the highest point of the West Gate Bridge. It is late afternoon. The sun is obscured by a ceiling of clouds that move briskly in the harsh wind that I am well privy to form my exposed vantage point. I have been beeped by drivers speeding by – even cheered on. But I am not here to jump. I am here to complete a pilgrimage started many months ago: to walk around Melbourne’s Port Philip Bay. I would separate my journey into a number of legs of several hours duration and by the end of the year try to have walked from Point Nepean to Werribee.
