With black pudding, pork sausages and the famous brown soda bread on the menu, it will turn into a full-blown grin.

Thursday is set to be a celebration of all things Irish on one of the biggest days on the calendar.

A uilleann piper will play Amhrán na bhFiann (The Soldiers Song), the country’s national anthem, from 7.20am before the breakfast gets underway.

Former Irish ambassador to Australia, Richard O’Brien, will toast the day.

A fiddler and guitarist will also entertain guests.

Uncle Bill O’Brien will perform the welcome to country.

Tickets are selling fast, with 140 snapped up so far.

Organisers are expecting walk-ins on Thursday.

Patrons will get a hearty fare, with bacon and eggs accompanying the black pudding and bread.

It will remind the ex-pats of their time on the Emerald Isle.

For the Aussies, it will be an insight into Irish culture.

“People will sit back and enjoy an hour and a half of Irishness in Port Macquarie,” Mr O’Brien said.

Further afield, there will also be plenty going on.

“It’s one of those quite extraordinary days on the international calendar,” Mr O’Brien said.

“Right around the world, there will be gatherings.”

The black stuff will flow at Finnian’s Irish Tavern.

Manager Zak Aylward predicted another big night.

“There are plenty of Irish blokes in town,” he said.

There will be bangers, mash and Irish stew all day.

Musical outfit Impudent Lager Wort will play that night.
