The essential workers stream is quite open. The language level is CLB 4, which makes it fairly accessible, and there's a huge range of occupations. In addition, with the way the hours are calculated, many seasonal agricultural workers could actually be eligible. For example, if they've earned the equivalent of one year of experience over multiple seasons, they may be eligible.
It is the same for part-time workers. The requirements for this pathway are not restricted to full-time workers. It's open to seasonal and part-time workers, and the requirement is to meet that one year of experience over the last three years. The pathway is fairly open and facilitative to support the different range of economic positions.
