No, it's yet another link to the MMM.
You see, when Debra first came to Queensland, she was actually based in Toowoomba, not Helidon. Just outside Toowoomba is Mt Tabletop. People would come on First Saturdays to go to Mass at Holy Name Church and hear Debra speak. Afterwards, they would all hop in their cars and drive to Mt Tabletop, which they would then climb. The MMM had erected a cross at the top, with each of the Stations of the Cross along the way.
The name makes sense now doesn't it?
