The Marlin Hotel is one hundreds of pubs across Australia that has joined the Let It Pour campaign, which aims to collect money and awareness for drought-stricken communities.

The Ulladulla pub and Sussex Tavern are two local venues that have registered for the October 25 to 27 fundraiser.

Launched by outback adventurer Matt Wright earlier this month, Let It Pour sees all proceeds from the sale of 1000 kegs donated by Great Northern Brewery Co going to the Rotary Clubs of Australia drought relief appeal.

The Let It Pour campaign raised more than $1 million last year.

Rotary's Philip Archer said the drought relief fund was organised by Rotary Australia and administered by Bendigo Bank.

"Last year, funds were given to people who needed help with everything from feed and water for livestock to school supplies for children, repairs for their farm machinery and food for their dinner tables," he said.

"They were overwhelmed and incredibly touched by the generosity of Australians in both urban and regional centres and found great comfort in their show of support as they turned out in droves to events across the country."

Great Northern's Antonia Ciorciari said last year's events united country and city communities.

"This year, pubs and clubs from Western Australia to Queensland and everywhere in between will be hosting live bands, sausage sizzles, bale tossing and other great activities to raise much-needed funds for our battling bushies," she said.

"It's going to be a lot of fun and all in the name of a good cause."

Ms Ciorciari said Let It Pour was Great Northern's way of giving back to some of its biggest supporters.

"Wherever you are in Australia on October 25 to 27, find your nearest pub, club or Rotary club hosting a Let it Pour event and raise your glass to the incredible resilience for our farmers as we all wish for better times ahead," she said.
