You mentioned in your earlier post that you're an invitee. As an invitee, secure all the necessary requirements that are needed for an invitee. A job offer is different as those are for offshore/onshore applicants who applied for a job in which employers will be assisting in securing a visa (working visa 457) for the potential employee, direct hire, after the employer had proven to QLD governing bodies that they are not able to find an employee in the field that they required.
As an invitee, your supposed to be visa are either to be 489, 189 or 190. You can proceed with your applications the same way as the others are processing theirs relative to migrant visas.
Hope this helps
