Permanent Residence (Skilled Regional) visa (subclass 191)

Hello, I am on a 491 Visa. I am the dependent on in a 491 visa and my spouse is the primary applicant. Due to some unavoidable circumstances my spouse is currently in the native country. Out of 5 years, our 16 months has already passed. Is it okay if I call my spouse later in Australia? Can I be the primary applicant at the time of 191 application? or is it necessary that ALL the visa holders have to complete 3 years? Please advise.

I am having visitor visa of Australia and want to explore further options for me

Sir, currently, I am staying in Australia on a 491 visa from mid-April 2025. Already submitted my first TAX assessment. If I go back to my home country and work there, what rules or documentation do I need to produce while applying for a 191 visa? Can I get the 191 visa? We are a family of 4 with 2 kids. If we take a consultancy to process my 191 visa documentation and application process as an agent, how much would you charge?

Received immi commencement email. Applied 191 on Sept 2024. What does that mean. No s56 received. Does that mean direct grant?
