The stars have aligned for a huge St Patrick's Day in Perth today with Irish workers flooding into the State and the Emerald Isle's most celebrated day falling on a Saturday.
There is expected to be more craic and more Guinness consumed than ever with Perth's Irish pubs preparing for thousands of revellers from 7am on.
Durty Nelly's function manager Adam Kapinkoff said celebrations in Perth were getting bigger every year and the pub was booked out for breakfast and lunch.
"It's by far our biggest day of the year," Mr Kapinkoff said.
Durty Nelly's is one of a raft of Irish-themed local pubs opening early to serve traditional Irish breakfasts before live music and Irish dancing continues into the night.
Perth workers Eimear Joyce and Eithne Healy went to high school in the same small town of Oughterard, County Galway but are in WA because there is no work at home.
Ms Joyce said St Patrick's Day celebrations in Perth had become just like home.
"It's basically the same because you are in an Irish pub and it is full of Irish people," she said.
WA Chamber of Commerce and Industry manager of migration services Ivan Hoe said the combination of high unemployment in Ireland and a shortage of workers in key industries in WA had resulted in a surge of Irish workers.
He said the number of Irish workers sponsored by employers for positions had more than doubled in the current financial year. In the first seven months there was a 159 per cent increase in visas granted to Irish workers to work in WA.
