The Queens Park Rangers forward is reportedly on Big Sam's radar.
It would be a brilliant move. The 26-year-old scored goals galore during a relegation battle last season and can hold the ball up for the likes of Jermain Defoe and Fabio Borini.
Aston Villa and Newcastle United were two sides who could have done with a striker like Austin over the summer. Their reward for ignoring an obvious goalscorer is the relegation zone after eight Premier League games.
Sunderland, too, are short of one and they, too, are in trouble.
But bringing Austin to the Black Cats would solve a lot of problems. As stated, it would give Allardyce's side a focal point. And, with a man like Big Sam in charge, the 26-year-old is bound to get plenty of opportunities from crosses and set-pieces.
The only stumbling block, of course, is whether Austin could actually be brought to Sunderland. The board on Wearside hardly splashed the cash when Dick Advocaat was in charge, while the QPR striker may want to remain at Loftus Road and then leave on a free to earn himself a signing-on fee.
But, if the QPR man can be persuaded - and Allardyce makes it clear it's his way or the highway in the January transfer market - Austin would be an absolutely superb signing for Sunderland.
