The swimming super-star was named on Monday as the brand ambassador for SunRice.

In her role as a brand ambassador Stephanie will be involved in the marketing of SunRice products including appearing on packaging and working with the SunRice team on product development.

Stephanie will also work closely with SunRice and their community programs, including their support of Unicef and various initiatives in regional Australia, including the Riverina area.

During her visit to Leeton she also met 300 school children at the local pool and ran a swim squad for 40 of the region’s best swimmers.

"This is a really exciting initiative to have secured Steph as our ambassador," SunRice chairman Gerry Lawson said.

"We are the best in the world at what we do and she’s the best in the world at what she does."

Stephanie said she was excited to be named as the company’s brand ambassador.

"It first appealed to me because I thought it would be really cool to endorse a product with the same name as me," she said.

"But it's a product I feel really strongly about, even before SunRice came to the table and I love the work they do with Unicef."
