Austin’s return to the starting line-up has provided significant dividends for Mauricio Pellegrino, with Sunday’s strike his third goal in as many games.
Southampton posed more of an early threat but Bournemouth were gifted the game’s opening goal as Wesley Hoedt was caught in possession – Ryan Fraser the eventual benefactor as he swept home his first league goal since January.
It was not enough to secure a much-needed home win for Eddie Howe’s side, though, as Southampton came roaring back after the break.
Austin was the man to eventually find a way through, his low strike beating the outstretched hand of Asmir Begovic to continue his fine form in front of goal.
Splitting the two south coast clubs proved impossible in the final 30 minutes, Austin twice going close, but the draw leaving both to settle for a point that sees them climb one place apiece in the table.
