If you’ve sponsored someone to visit Australia and their visa was approved but hasn’t yet expired, you can only sponsor other members of their family who want to visit for the same reason. For instance:

Let’s say you sponsored your uncle’s visit. His visa is still valid, and now his daughter (your cousin) and your mother want to visit before his visa expires. In this case, you can only sponsor your uncle’s daughter (your cousin) because she’s a part of his family unit. However, she must also intend to visit for the same purpose as your uncle’s initial visit. If her application states a different reason, her visa might get refused. You’ll only be able to sponsor your mother after your uncle’s visa has expired.

Now, if you sponsored someone and their visa has expired because they didn’t follow the visa conditions, you won’t be able to sponsor another person for five years from the date their previous visa was granted. However, there’s an exception: if the previous visitor breached condition 8531 (staying beyond the visa period) due to circumstances beyond their control after entering Australia, this restriction can be waived. But generally, the five-year limitation applies if the previous visitor didn’t comply with their visa conditions.
