Student visa offshore after 485 visa

Hey everyone, I came to Australia in 2020 and studied bachelors of biomedical science, after that I applied for my TR in 2023 which lasted till this year march and throughout that time I have been working as a laboratory assistant.

Now my TR has expired and I have been unsuccessful in finding a sponsor in my field as a laboratory technician. I have came back offshore to start a new student visa procedure but I am highly unsure if I will get a new visa or anything. If anyone has any clue on current student visa turn around times or knows someone who has been through a similar situation like this please let me know.

Moreover, I am happy for any guidance or links if you can provide me some for my situation!
