5G is on the way, page-8

Wireless is not an option till its data downloads are cheaper to the consumer.

I could not afford to pay for, on average, 40G a month for data
5G mobile data pack from Telstra $35

While I am very underwhelmed with my NBN FTTN connection, it is cost effective. My bundle price actually went down when I switched over.

Something needs to change before it is cost effective, I have no concerns with them eventually solving capacity issues.
How long, don't know.
