Liz can put you on an email list and she will email you monthly with whats happening and what tours she is doing...well worth it, I do.
I've been on many of her tours including the investigation she did at the old Campbelltown Theatre. That was an interesting night especially if you are into EVP's.
The tunnel has been closed now for a few months due to the Council declaring it unsafe due to cracks in the walls, but she still stands at the entrance of the tunnel to see Emily and the orbs dancing along the roof. Only thing is though, I'm not sure if the short bald headed spirit will make an appearance, he usually blocks you from getting too close to Emily.
On one tour, my friend had gotten back to her car and noticed tiny handprints on the car. When we got home she took a photo of them, then washed the car the next day, only to find the dusty prints returned.
