I don't think that you got baited and switched with Julie. There is only one Julie. I've seen her a couple of times and she is as described in your post ("bolted on rock hard DDs"). The photo of Julie in the red lingerie was the photo that was first used on the web site when Julie started working at Pymble House in early 2024. The photo of Julie in white was added to the web site a few weeks later and the two photos that you thought were fake were added in July 2024. Of course the description of her on the web site isn't accurate.
The manager at Pymble House told me she took the two photos of Julie that you thought were fake as well as this photo:
