@mariusinbrisbane Almost all Australian workplaces look for "local experience" no matter which industry you are. Overseas work experience are not seen as relevant unless you gain that local experience (at least one year, according to a friend).
As kramkramkram said, it's going to be difficult to secure a job unless you have specialized skills (again, it doesn't matter which industry), because employers prefer people who have PR/citizenship. It will cost them more money and time just to process that visa sponsorship. With the current pandemic and closed border, onshore applicants are more likely to be considered than offshore. There's no telling when this situation will change. If you are offshore, maybe directly going for PR visa is a better option for you?
A non-IT example of specialized skill is a friend who was able to secure visa sponsorship (temporary work visa and also employer-sponsored PR visa) because of their expertise in nanoscience/quantum computing.
