Are you sure Cherie went to the same school? I've never come across that info before

Yes. The following is from a Channel 9 article from 30/7/2017:

Police keep in contact with Ms Schulz. When Boronia schoolgirl Bung Siriboon vanished, Cherie's case became a detail in the investigation.

The pair went to the same school, prompting police to investigate if there was any link between the two cases.

"We know what Bung's family went through. She vanished without a trace,” Ms Schulz said.

Seventeen years since Cherie vanished, Ms Schulz has moved away from Melbourne.

I think Cherie attended a few high schools, i thought she went to Ferntree Gully Secondary College (which closed around 2005/2006).
