Under this category, an Australian citizen, Australian permanent resident, or eligible New Zealand citizen can sponsor their child for Australian visa. You can sponsor a biological or adopted child, as well as the orphan relative. This category requires the child to be offshore to meet the criteria.
Usually a child under the age of 18 can be sponsored unless they are:
1. a full-time student
2. aged under 25 years and
3. are financially dependent on the sponsoring parent, or
4. have a disability due to which they cannot work.
