Do you know all the words to Advance Australia Fair? What about the second verse?
Alright — what about another country's anthem?
Brisbane sisters Augnes and Teresa Joy can belt out all 195 of the world's national anthems as recognised by the United Nations.
"At the start, everything was hard to learn," 21-year-old Teresa told ABC Radio Brisbane.
"We just started learning and each national anthem that we learnt, we just found it more interesting and we wanted to learn more."
The pair, who speak the Indian language Malayalam as well as English, are able to seamlessly break into an a cappella rendition of any country's national song in the native language.
Augnes, a year 12 student and Teresa, who is in her third year of university, have big plans for their massive repertoire.
"Our mission is to sing all these countries' national anthems to promote world peace, children and women empowerment, and a real sense of humanity," Teresa said.
"That's our main goal."
Dad sparked passion
But they certainly did not learn the anthems overnight.
"It took us eight years and it was actually our dad's idea," 17-year-old Augnes said.
"We wake up at 5:00am every morning and study for two hours to sing the national anthems.
"[Our dad] wanted us to do something different for the world and contribute something.
Raising voices to raise money
Augnes said some anthems were easier than others.
"The shortest one is Japan and the longest one is Greece," she said.
The sisters' project will be launched in Brisbane by the United Nations Association of Australia as part of the International Day of Peace on September 21.
They hope the funds raised will be put toward charitable activities run by the UN.
