Yesterday, more than 17,000 people pledged their allegiance to the nation in about 400 ceremonies across the country.

In Wagga, 28 people from 14 countries became Australian citizens in a half-an-hour ceremony, which included a performance by the Holy Trinity Aboriginal dance group.

Tanzanian father Obed Manirakiza and his children Dikeni Tuombemola, 13, Adelphine Nishimwe, 11, and Dickson Nshimirimana, 7, all became citizens at the ceremony.

"Wagga has given us so many opportunities," Mr Manirakiza.

"We are all very pleased to have become citizens."

Member for Wagga Daryl Maguire spoke about the new "journey" that has began for the 28 new citizens, and read a statement by Immigration Minister Scott Morrison, which asked Australians to reflect on their privileges and responsibilities.

Wagga mayor Rod Kendall said citizenship meant many things, but it certainly didn't mean leaving their past behind.

"You can bring your culture to us you don't need to leave it at the door," Cr Kendall said.

"Multiculturalism is part of what makes this country great."
