What does the national guarantee mean for skilled immigrants in Australia?

Generally speaking, the participating countries/regions will select the applicant as the nominee from the "Technology Matching Database" according to the country/region. Applicants can also directly contact the participating States/regions through the relevant links of the Australian Immigration Bureau. Because the occupation of the nominated applicant is in short supply around here, the applicant should be able to find a job soon after moving. However, the nominated state or territory government does not guarantee any employment after immigration.
