正在给父亲在网上申请600签证，这个问题不知道要怎么回答：
Non-accompanying members of the family unit
Does the applicant have any members of their family unit not travelling to Australia who are not Australian citizens or Australian permanent residents?
网站给出的解释是：
Non-migrating members of the family unit
Include any member of your family unit who would normally be included in this application but who does not require a visa. This member of your family unit may not be migrating to Australia or they may hold Australian citizenship.
There are further questions on the partner visa forms to gather information about the applicant's extended family members.
In some circumstances, this member of the family unit will be required to undergo health and character clearances.
This member of your family unit may wish to migrate later but must be aware that they will need to meet visa eligibility requirements in their own right at that time unless they meet visa requirements as part of this application and can travel within the validity of the visa.
A family member who already holds a valid visa or Australian Citizenship who may be travelling to Australia for residence with the family unit will not need to be included in the family migration application. However, they should be recorded as non-migrating members of your family unit.
Note: If this non-migrating member of your family unit does not hold a passport then enter their name and date of birth but leave the passport details questions blank.
请问：
1. 我母亲目前持有600签证且正在澳洲，是否应该作为Non-accompanying members of the family unit？
2. 我是PR且正在澳洲，是否应该作为Non-accompanying members of the family unit？
谢谢！
