Electric Fields said they were proud of their "killer" performance and will take fond memories from Eurovision despite missing out on a spot in this weekend's final.
The duo competed in Semi Final 1 at Malmö in Sweden on Wednesday morning but were not one of the ten countries that made it through.
Vocalist Zaachariaha Fielding and keyboard player and producer Michael Ross have been performing as Electric Fields since 2015.
Speaking after the performance, Fielding said the weight had been lifted off their shoulders, adding he felt "really good".
He said: "We can breathe, we're still buzzing from the three minutes.
"We did a killer performance, we felt like rockstars, that audience was just absolutely giving.
"It's going to be a memory that will be embedded with us for the rest of our lives."
Electric Fields performed their song One Milkali, and it was the first time an Aboriginal language joined about 78 languages and dialects that have graced the Eurovision stage since its inception in 1956.
The qualifiers were Serbia, Portugal, Slovenia, Ukraine, Lithuania, Finland, Cyprus, Croatia, Ireland and Luxembourg.
The United Kingdom, Germany, France, Italy and Spain automatically qualify for the final each year, alongside the host country.
Semi Final 2 will be broadcast live from 8.30am AEST on Friday 10 May, and the final will be held at 5am AEST on Sunday 12 May, both on SBS and available on SBS On Demand.
One Milkali features words in the Yankunytjatjara dialect from the Anangu peoples in South Australia's APY Lands — where Fielding grew up surrounded by songlines and dance.
The language is listed as endangered with only a few hundred remaining speakers today.
