5 Year Gap for Partner Sponsor Limitation Period.
In general, a Partner Visa Sponsor who has previously sponsored a partner (or prospective marriage) visa applicant is not able to sponsor another partner (or prospective marriage visa) applicant until at least five years have passed since the date of the first application. (Not the grant date, the application date)
A person may sponsor two partner or prospective marriage visa applicants in total.
The 5 years is calculated from the date of the previous visa application to the date of approval/refusal of the current sponsorship.
A sponsor, who was previously sponsored as a partner or prospective marriage visa holder, is also not allowed to sponsor a partner, or prospective marriage visa, applicant until at least five years have passed since the date of their own visa application.
There are limited exemptions for this, especially where young children are involved in the new relationship.
Some Visa Applicants might find an Experienced Australian Migration Agent of great assistance.
