929 is the form. The email address is for completed copies of the form.
Permanent residents are a class of non citizens who have the right to permanently reside in Australia. Most cannot vote.
All of it can be done online through their portal. The Australian government spies on everyone anyway so using the portal presents no increased attack surface for anyone who would care.
Really it's there as a legacy technology. Most people under 35 would certainly use a portal. Probably most of them over 35 as well at this point.
If you used an immigration lawyer to apply for permanent residency, you can't use the portal to make those updates, because the original visa is not associated to your portal account.
So your only other option besides emailing the form, is to print it and bring it in person to an office.

A few months ago I changed my PR subclass and the new application was done using the portal. Which means that I can finally use the portal to update my details.
