What do I need to stay accredited and be nominated for events?

AusTriathlon's technical official page lists these requirements:

• An active AusTriathlon membership with a Technical Official add-on (Technical Official membership is free, with rebates available based on contribution to the program).
• A valid Working With Children Check (Working with Children Check/Vulnerable People compliance).
• For event nomination: a current Technical Official membership, a valid Working With Children Check and a current LTO, RTO or ATO accreditation.
• Reaccreditation: "Every 12 months Technical Officials will be required to complete a Reaccreditation process." The window opens three months before expiry.

Questions go to technical@triathlon.org.au.
