Can I apply 482 visa by myself?

Can I inquire about the process of applying for a 482 visa on my own? I understand that it's typically a sponsored visa, but is there a way for me to navigate the application process independently? I'm particularly interested in knowing the eligibility criteria, necessary documentation, and any potential challenges or limitations I might encounter if I choose to apply solo. Additionally, are there any benefits or drawbacks to self-application versus going through a sponsor or migration agent?
