Applying for Australian citizenship wasn't an easy decision for Sandy and Tony Liu, of Illawong.
China does not recognize dual nationality for its citizens and so, when the Liu family become Australian citizens on Australia Day, they will lose their Chinese citizenship.
A total of 165 people from 43 countries, including China, Nepal, South Africa, Germany and Sri Lanka, will swear the oath of allegiance to Australia at Sutherland Entertainment Centre.
Ms Liu had a career in imports and exports in China when the opportunity came in 2007 to work for a period in Adelaide.
"I came out for a look, and liked it so much my husband followed me to Australia a year later," she said.
"After four years in Adelaide, I was offered a job in Sydney, and so we moved to a flat in Hurstville and then bought a house in Illawong."
Their daughter Alice was born in 2010 and attends Tharawal Public School.
Mr Liu, a warehouse supervisor, and his wife decided to seek citizenship after obtaining permanent residency.
"I love the weather in Australia and the people are very friendly," Ms Liu said.
"Illawong is so quiet and peaceful. I have friends who also live here.
"We are very excited to become Australian citizens.
"It was a big decision, because we have to give up our Chinese citizenship, but we feel Australia is our home. I don't think we will ever go back to China to live."
