is it mandatory to update address on 485 visa?

Let's say one is in 485 Visa using current address(A) while it was granted.

Should I update my address within some particular days(T) if I move interstate B?

are there any consequences if someone fails to change or update their address(from A to B) while in 485 within that period, and later claims to be in state B during those period(T) to claim points or lodge a permanant residency?
