Sorry, I’m not privy to Norton “why”.
fwiw ~ at this time:
Norton 360 & Web Shield blocks https://wantirnaosteo.com.au/ = URL:Phishing
Norton Safe Web extension blocks https://wantirnaosteo.com.au/ = “known dangerous webpage”
Maybe, IP address traffic here is causal.

Note: after submitting dispute and waiting 48 business hours with no change.
Please contact Norton support and advise support that you’ve submitted dispute and waited 48 business hours. My understanding is…once you state that you have already submitted False Positive over the submission portal and waited 48 business hours…support agent shall take the URL and detection screenshot and advance the case.
