Post approval - existing applications

The Chief Investigator must ensure the following requirements are met throughout the life of the project:

  • Amendments or project modifications
  • Change of Investigator, or additional investigators (including students)
  • Adverse Events
  • Complaints

Amendments or project modifications

Amendments should be submitted for review as soon as possible. There are no submission deadlines for amendments. 

Requests to change personnel only or change funding only are considered by the Ethics Secretariat and can be submitted at any time. Larger amendment requests are considered by the HREC or Executive, and should be submitted by the cut-off date for the next available meeting.

It is the responsibility of the Principal Investigator to ensure HREC approval is obtained for all amendments prior to implementation. Failure to conduct research according to an ethically approved protocol risks researchers' legal indemnity, right to publication and opportunity to seek future funding.

An amendment may include but is not limited to:

  • Changes to the protocol
  • Changes in recruitment strategies
  • Changes to Information Statements and Consent Forms
  • Changes to letters, advertisements, questionnaires or any other documents.

Where modifications require changes to public document(s) such as Participant Information Statements, Consent Forms, advertisements and questionnaires, you should include amended documentation with your modification request. Please provide tracked and clean copies of any amended documentation.

For all amendments to the approved project, including change of staff and/or students on the project, complete the Amendment Form and email to

Change of investigator 

To comply with the requirements of the National Statement on Ethical Conduct of Human Research 2007, researchers must notify the reviewing HREC and authorising institution of any changes to the study team.

Please note that students are required by the Higher Degree Research Office to provide evidence of ethical approval to submit their theses for assessment.

Adverse events

Adverse events should be reported to the HREC as soon as possible.

To report an adverse event, researchers should submit an Adverse Event Form with any relevant documentation to

An adverse event is a harmful, unpleasant or undesirable response, reaction or outcome experienced by a research participant or researcher. Such incidents may include unanticipated harm to participants or harm to the reputation of the researchers and the University.
