SBS On Demand has previously been available via web browsers, Xbox, PlayStation 3, Windows 8 and various Internet-connected TVs.
Now there's a free iOS app for SBS On Demand that works with the iPad, iPhone and iPod touch.
The video quality automatically adjusts to suit the network conditions being experienced to ensure smooth playback regardless of available bandwidth or other issues.
Apart from the ability to search, browse and view "thousands" of programs including documentaries, movies and food shows, the app has a playlist feature that interoperates with the other versions of On Demand.
"The SBS On Demand app is a fantastic new addition to the continually expanding range of SBS apps we have launched across multiple platforms," said Marshall Heald, director of online and emerging platforms at SBS.
"SBS On Demand's rapid expansion is proof of our commitment to ensuring our audience can access SBS content where and when they want it," he added.
SBS has acknowledged a bug in the app: when it is being used in conjunction with the AirPlay feature, videos containing advertising return to the start of the program after an ad plays.
"We're currently working towards a solution on this," said SBS officials via the app's description in the iTunes Store.
Apart from that, initial feedback from users is mostly positive.
