This paper utilises the occupational attainment approach to investigate immigrant labour market assimilation, complementing other assimilation approaches such as employability, earnings, skills-match and job satisfaction. Our results show that all immigrant groups suffer from initial occupational attainment disadvantage. Worryingly, no ‘catch-up’ over time is evident – even when disaggregated to reflect different cultures and backgrounds. Nor is there much evidence that the occupational status of younger arrivals matches those of Australian born residents, despite being immersed in local mores and institutions while undertaking schooling in Australia. Newer cohorts of immigrants (those who arrived between 2000 and 2014) are also more prone to suffering an occupational penalty. We recommend policymakers subsidise bridging courses to aid recognition of overseas-obtained qualifications and encourage immigrants to obtain local qualifications that can complement their overseas-obtained work experience. This will increase their ‘Australian-ready’ skill-set and occupational attainment in their new host country.
