Social media is making the job of collecting Australia's quintessential sounds harder.
Each year, the National Film and Sound Archive of Australia collects and stores tunes that reflect life Down Under and Australian heritage.
There are now more than 70 tracks - some of news reports, birds chirping, and a Kylie Minogue song - all as diverse as the land from which they originate.
But this year, public nominations tripled, leaving the curators in Canberra overwhelmed by submissions on Facebook, Twitter and email.
It's made the task of short-listing the top 10 tracks much harder, says sound curator Matthew Davies.
"This year, we have seen more public interest in Sounds of Australia than ever before," he said in a statement on Wednesday.
"We ... had a number of excellent nominations that have not made it onto this year's list.
"But with only 10 new sounds added each year to represent over 100 years of history, we have had to make some hard choices."
Thankfully, the curators succeeded.
They don't get as iconic as Peter Allen's song I Still Call Australia Home, or as powerful as Archie Roach's song about the stolen generations, Took the Children Away.
Both have been stored and locked into this year's Sounds of Australia registry, among the yearly list.
There's also Russell Morris's Molly Meldrum-produced single The Real Thing, and a 1913 song by war time idol Florrie Forde.
Beyond songs, the collection also includes Roy and HG's Triple J show from 1986-2008, This Sporting Life, and a recording of a lyrebird mimicking the sounds of a video game.
