Chinese passport expiring. Can I apply renewal online or do I have to go to China Consulate in Mel?

I live in Melbourne and I am a Chinese national. My passport is expiring in a few months. Do I have to go to China Consulate in Melbourne in person to apply for renewal or can I do it online?

Also I heard of digital Chinese passport somewhere. Is it a different process as of applying for a digital one?

Thank you very much!
