If I can't post this please remove. Maybe a local can confirm, but Google produces two locations for Yarrabee farms (one in town and one at the farm south of town). The one shown in town is right down the street from the Jack's residence and would have probably been in sight of her running south.

That looks like it may be the migrant house folks are talking about. Perhaps it is owned by Yarrabee and that's where the workers live? Or maybe it's just a Google addressing error.
