Sea Eagles captain Jamie Lyon is a proud country boy and he's encouraging fans to show their support in a Cow Pat Lotto to be drawn at halftime of this Sunday's clash with Cronulla at Brookvale Oval.

"The fans just buy a lot and whoever gets that lot wins. It's just like buying a raffle ticket I suppose. Whoever gets it gets a prize", Lyon said.

Growing up in the small country New South Wales town of Wee Waa, Lyon regularly participated in Cow Pat Lottos during his school years and says he's looking forward to bringing the concept to Brookie.

"We used to do it at school at Wee Waa primary. We used to have it every year at the fetes. I never used to win it though", he joked.

"The lucky winner gets a prize. I think it's a thousand dollars so it'll be good to see who wins it."

At just $5 a ticket to guess the square on the oval the cow will "go", all ticket holders stand the chance to win a massive $1000 from IGA Allambie Heights and Castlecrag.

Tickets can be bought on the day. The half time entertainment will be watching to see where the cow went and revealing the winner of the meat tray.

All funds raised go towards supporting families from the country who need specialised medical and educational support from Royal Far West, a 90 year old charity based in Manly and a keen supporter of the Sea Eagles.
