Do I need to update my WDRP Whois Domain Registrant Details outside of Route 53?

I recently received an email from ICANN showing incorrect contact information for one of my AU registered domains. Just prior to receiving the email, I had updated my address details with Route 53, having just recently moved to a new address.

I’m now wondering if ICANN’s registrant details are something that is kept up-to-date when contact information is changed in Route 53, or if I need to contact ICANN (or 1API GmbH in my case), directly, to have my details updated there as well?

All assistance is greatly appreciated, Thanks! A
