Do I Have Any Rights?

Cut long story short:
Worked for a employer who maltreated patient (s), over many years of having worked loyally in a private dental practice.
Towards the end of my employment, few staff members and one particular employer, was bullying and harassing me for no legit reason.
The last incident, was in no way, shape or form, deemed appropriate. This employer:
- assaulted patient with dental tools
- harassing patient by not letting them go to the toilet and raising their voice at them for no legit reason
- treating me like dirt whilst assisting them and the patient, the best way I could, given the circumstances.
- defaming my name. Never able to return back into my career because of the maltreatment/bullying and harassment, I was receiving from potential employers
Put in a complaint with dental board and AHPRA
Never took my complaint seriously.
Informed me that I had no proof and evidence.
They said they had a witness to what was going on that day, incident occurred??? It was only the Doc, myself and patient.
Other nurse was at the front desk. she could not hear or see anything.
Due to the lack of proof and evidence, my case
was never heard.
Not sure about how the Dental Board conducts themselves with complaints?
Without facts, they twisted everything in the favour of employer and made me look like the perpetrator.
I have also been accused of being a whistle-blower and that no one would hire me, even if I did do well in the exams??
These employers have ruined my life and reputation and they do not care.
No one was able to assist me because all the cards were stacked up against me.
No workmen's compensation or justice has resulted from my compliant.
I am still grieving, in shock and in total disbelief over what has happened.
Can you please give me any suggestions on how to move forward?
