The Sydney Fish Market is reeling in a record number of shoppers visiting its traditional 36-hour pre-Christmas trade marathon.
More than 77,000 people have tackled the crowds and packed their eskies full of seafood since 5am on December 23, with organisers expecting records to be broken this year.
"Last year we had a massive 114,000 people and we're tracking to beat that this year," Sydney Fish Market general manager Bryan Skepper told AAP on Sunday.
"It's great fun, it never ceases to amaze me. People come here with the expectation it's going to be crowded but everyone is relaxed and treat this as part of the Christmas experience."
Retailers worked throughout the night on Saturday, with shoppers making the most of the 36-hour trading marathon, but the big rush is still expected to come as it nears closer to the closing of shutter doors at 5pm on Christmas Eve.
Prawns have been the number one seller, with oysters and blue swimmer crabs also popular among the shoppers, Mr Skepper said.
"Christmas being a family celebration time, people look for something special," he said.
"My favourite is the smoked salmon, it goes together with Christmas perfectly."
After flying in from New Zealand on Saturday night, Karin Challeeder was at the markets bright and early on Sunday morning.
"I've never seen anything like this, it's just amazing," Ms Challeeder told AAP.
Arms full of bags packed with prawns and octopus, Tonga Tapukalanga is a regular to the markets, making the trip every year before Christmas Day.
"It's the spirit of Christmas," she told AAP.
