Congratulations are streaming for basketballer Lauren Jackson on Twitter, and she tweets it has been "funnn" to be a trending topic for the first time.

Jackson, 31, is the first Australian woman to be named flag bearer in 20 years. Diver Jenny Donnet was given the same honor in Barcelona in 1992.

She is a 3-time Olympian with three silver medals under her belt.

"This moment makes me feel like nothing's impossible," Jackson told reporters.

"When Nick Green [Australia's chef de mission] asked me I thought 'why?' It is a great honor," she said, later adding, "I can't think of anything that would ever top this. Obviously a gold medal would be awesome, but I feel like this is something that will never happen again."

Here are some of the congratulatory tweets that have streamed on Twitter following the announcement that Jackson will be Australia's flag bearer at the London Olympics:
