Marg944, I hadn't seen the ute in York Place. Well done! (I don't know which one you're talking about in "parked at her home": do you mean the Dover Heights house?)
Here's a wide view of the York Place street, from the ute on the left (parked next to the side of 17 B******* Road) across to 2 York Place on the right, where the woman is at the mailbox:

After the Street View car goes past I think it continues past 4 Y*** Place next door, and by the time it is just around the corner the camera (presumably looking backwards) captures the woman walking on the street near the ute. Here's a close-up of the view from about 34 Y*** Place:

And by the time the camera has moved just one driveway further away, to about 32 Y*** Place, the woman can't be seen at all - this is a wide view:

Maybe the Street View car stopped for a while and the woman walked away unfilmed; or maybe the woman turned around and went back to No.2. And maybe it wasn't Melissa anyway (the woman looks more solidly-built than I expected Melissa would look). But IMO it's also possible that it
was Melissa and she got into the passenger seat of that ute.
