You have to report the actions of the centre and also look at what the centres anti bullying policy says. It is a breach of privacy in giving out your personal details without your consent.
WA does not have its own privacy legislation but here is some information about the Cth Legislation.
What your employer is doing blaming you is bullying and intimidation by the employer and this is not allowed by the Fair Work Act and you should speak to a solicitor in WA and have a letter sent to them to back off and admit they made a mistake and stop what they are doing.
You may not want to sue but they have to be put in their place so they know they cannot do this to you and they have yo pay you.
