Not only has it just been announced as a finalist in the Delicious Produce Awards 2015, Australia's only national food awards, it will receive further promotion through Channel 7's Sydney Weekender show.

A television crew visited owners Gary and Jo Rodely in Tathra last week to film a segment for the show, which is expected to be aired in the next few weeks.

The Rodelys have tasted success in the ABC Delicious magazine competition in the past, winning the national judging in its category in 2012.

"We are very excited about reaching the finals again," Mr Rodely said on Monday.

Tathra Oysters has placed in the From the Sea award category of 'Bistro Grade' oysters (Primary).

"This year we are the only NSW producer finalist in the From the Sea category," Mr Rodely said.

This is the fourth time the business has been successfully nominated for the awards.

"It's quite a lengthy process to go through, but it's wonderful exposure for us as it is a very well-recognised and regarded food award in Australia."

The 2015 finalist list is the result of state judges meeting to taste their way through the crop of primary and artisan nominees.

The state judges were tasked with selecting the best of their state in the Earth, Dairy, Paddock and Sea categories to progress through to the final round of national judging.

"There are also well-regarded food people involved in judging the awards with names like Matt Moran, Maggie Beer and Guillaume Brahimi," Mr Rodely said.

Tathra Oysters is a small family business - with son Sam assisting as farm manager - which prides itself on producing a high-quality product.

Grown in the pristine Nelson Lake waters it has been attracting the attention of some very high-profile Australian chefs and restaurant owners.

This particular species, the Sydney rock oyster, only grows on the NSW coastline.

Mr Rodely said it is a rare species in increasing demand.

"Our season has finished now, but we had a really nice season this year.

"We had early rainfall, when the oysters were getting fat.

"These oysters have been sold in more than 20 Sydney and Melbourne restaurants for the better part of four months this year.

"Many of these restaurants are putting on their menus they are Tathra Oysters, so we are very pleased about that," Mr Rodely said.

The finalists' produce is blind-tasted by a national panel of judges who decide the overall category winners, which are revealed at a special event in Sydney on July 27.

"We are in there with a chance of winning.

"Even if we don't win the final, attending the event in July is a good opportunity to rub shoulders with the who's who of the industry," Mr Rodely said.
