You're lucky that it is already in further assessment stage. We lodged the visa application in June 2022 but it is now in further assessment stage. Now that the processing times are increased to 22 months, we cannot predict by when the grant can be expected. Only thing we can do is remain patient!
The processing times for visa applications, including the South Australia 491 visa, vary widely based on several factors. These factors include the complexity of your application, the number of applications in the queue, changes in immigration policies, and the completeness of your submitted documentation.
The "Further Assessment" status typically indicates that your application is still being processed and no final decision has been made. It's common for visa processing times to vary; some applications might take longer than expected.
