If you hold a COVID visa subclass 408 which is due to expire in less than 90 days and you have a valid job offer, you can apply for a second COVID visa. In most cases, you can stay on a COVID visa for up to 4 years.
Please note that this is true at the time of this post. The department may halt this visa option in the coming days or months.
If you need Immigration assistance get in touch by making an appointment for a phone/video consultation or ask for a written consultation.
