Voice. Treaty. Truth. Let's work together for a shared future are key elements of this year's NAIDOC theme and these words were used extensively at the school's recent assembly.

The United Nations is also celebrating International Year of Indigenous Languages which was also acknowledged at the event.

Teacher Miss Georgia Sadler spent hours of her own time with Local Aboriginal Land Council representatives to translate the song 'I am Australian' into the local Dhurga language.

She then had to fit the translation into the original tune of the song and then taught it to her school choir to perform at the assembly.

It proved to be just one of the many highlights of the assembly.

Fellow teacher Michelle McBride also wrote a song, performed at the ceremony, while two students from Ulladulla High, Jayden Perry and Riley Nolan played by the didgeridoo.

Many students sang, danced and in general beamed with pride as they performed in front of their family, friends and special guests.

One of the special guests was elder Aunty Nell Mooney.

Aunty Nell gave the Welcome to Country address and spoke about the need for all Australian to heal and move forward as one.

Principal Mr Trent Burns also addressed the audience.

"I would like to acknowledge the traditional custodians of this land and of elders past present," he said.

"I would also like to acknowledge the history of their rich culture that exists around us, underneath us and inside us.

"I would like to pay my respects to the Aboriginal and Torres Strait Islander people present here today."

Mr Burns said many things make Aboriginal and Torres Strait Islander people special, including that fact they are members oldest indigenous culture in the world.

Rousing applause from the audience capped off a great assembly.
