2015 has been a big year for SBS, celebrating 40 years on the air.
It all began with eight languages on SBS Radio in 1975.
Since then, SBS has grown into a multimedia broadcaster highlighting the many languages and cultures of Australia.
SBS Cantonese broadcaster Ivan Leung is in Chatswood, a northern Sydney suburb where more than 31 per cent of the residents claim Chinese ancestry.
He is chatting with a listener in Cantonese.
The many Chinese-owned businesses in the area reflect the community's strong entrepreneurial history, which dates back to early European settlement.
Ivan Leung says it is nothing unusual for his community.
"We are a bunch of hard-working people. We can work for a long time, and it actually brings in a different culture to our commercial sectors as well. And, also, we push our opening hours so that people can shop in the later hours, rather than, when people are off work, they can only go home."
Ivan Leung says the Cantonese program attracts loyal listeners from the community and the enduring appeal of radio remains its ability to connect through storytelling.
"In the old days, the Chinese, they had a bit of storytellers. They're telling stories in the street. They're not just repeating the story every time they tell it, but they actually enhance it, they reproduce it. This also works for radio as well. That's why we love to tell a story on SBS Radio."
At federation, 30,000 Chinese people were in Australia.
But the introduction of the Immigration Restriction Act, commonly known as the White Australia Policy, halted Chinese migration in the early 1900s.
Many other non-European races were also largely excluded from migrating until the second half of the 20th century.
By the 2011 census, more than 860,000 Australians claimed Chinese ancestry, making the Chinese community one of the country's most established.
And the community's needs have evolved as it has grown.
Henry Pan is executive director of the Chinese Australian Service Society, which has provided welfare services to the Chinese community since the early 1980s.
"For young migrants, actually, they need childcare and also education, knowing the health system, the tax system -- in short, how to have a good living in Australia so that they can settle into the community well."
Mr Pan says the Service Society also helps older Chinese-Australians, many of whom arrived through the family-reunion scheme.
Mandarin is the most commonly spoken language after English in Australia, with the number of speakers jumping from 200,000 in 2001 to more than 330,000 in 2011.
Cantonese is also one of the most commonly spoken languages, with just over 250,000 speakers.
In China, Mandarin is the official language, and Cantonese is widely spoken.
It is those two languages that have been broadcasting on SBS Radio for 40 years.
Alan Qu is one of the voices behind the Mandarin program.
In the internet age, the program uses social media to promote its stories.
With Facebook banned in China and not widely used by the diaspora in Australia, the program relies on Chinese social-media programs Weibo and Wechat to promote its content.
Alan Qu explains it has its positive and negatives.
"The reason that we didn't use Facebook is because it's forbidden in the Chinese mainland, so there are not many Chinese users, even in Australia. The information we publish on Weibo and Wechat, it is kind of being monitored or supervised by the Chinese government as well before it is released to the public. If there is some information that is quite sensitive, the information would be blocked or even our account would be frozen for a little while. We commented on the anti-corruption thing from the Chinese government, and, for some very sensitive words, our account was frozen for three days."
But beyond social media, the program knows it has a direct impact on some of its listeners' lives.
A recent interview on the program about a domestic-violence service inspired one listener to flee an abusive relationship.
"We were just broadcasting the anti-domestic-violence program and promoting some telephone numbers and the organisations you can go to to seek help, and, on that day, she just grabbed the phone and called the group and got rescued."
Mr Qu says it is an example of how important the program has become in covering vital issues for Australia's Chinese community.
"From our perspective, we are doing a daily job as journalists -- it's the same every day -- but, for someone, it could be a life-changing thing. And some information we provide, sometimes we can save their lives."
