Parked or moored?
My guess is that the PCX is probably of one of that beauty's crew members. The owner will, most likely, have someone drive him around town in a Bentley or the like

Shame on me, I haven't been to Melbourne. Had the chance and skipped it, now I regret it. At the time I had the chance I was dating an Aussie girl and she's a Sydneysider, so it made sense to stay in NSW. Australia is just too big to see all that's worth being seen in just one life!
