Bakers at Braidwood started early on Christmas night but could not bake enough fresh bread and buns for hungry travellers heading to the south coast on Boxing Day.
Braidwood Bakery co-owner John Woodman said they sold out of 500 units of freshly baked breads, buns and egg and bacon rolls by early afternoon.
He estimated about 5000 people came through the doors for the day, which wound up about 8pm.
''It's been super, fantastic,'' he said.
Staff opened the doors at 5.30am on Boxing Day, when people were already knocking on the front door.
Seven staff were bolstered by five reinforcements over the frantic lunch period.
Mr Woodman said trading was on par with Boxing Day numbers over the past three years.
His father, Keith, a former rabbit trapper and motelier, opened Goulburn's Trappers Bakery in 2006 and opened another one in Wagga in July last year.
Keith runs the fast-growing business with his daughter Jeanette and John.
They have also bought a site near McDonald's at Gundagai and hope to open there in March.
There were long queues for coffee and cakes on the Braidwood bakery's second-busiest day of the year, which is only eclipsed by Easter.
''The last six months, retailers down the coast have been telling us their trading is down about 10 per cent,'' Mr Woodman said.
''We have been down a little but this year is on par with previous years.''
