Premier Mark McGowan says there are about 31,000 jobs that need filling across WA, including roles for teachers, police officers, nurses, doctors, dentists, mechanics, builders, plumbers and miners.
"We have seen economic growth that has defied global trends and continued to create quality, well-paying jobs," Mr McGowan said on Friday.
"To fill these vacancies, we know that we need more people to call Western Australia home."
The delegation will spruik WA's salaries, that are often more than 50 per cent higher than the average English salary for the same occupation, and comparatively lower cost of living, according to the WA government.
"Since I visited the UK and Ireland last year, our message has been clear - Western Australia is a safe and exciting place to live, study, visit and do business," Mr McGowan said.
The mission includes events in London, Edinburgh, Bristol and Dublin, information sessions and an advertising campaign targeting specific professions, such as the 'Build a life in WA' campaign to attract construction and manufacturing workers.
The adverts will also promote WA as a unique location offering secure jobs and about 3,200 hours of sunshine annually.
