Captain Steven Davis fired home a late fourth as Southampton strolled to just their fifth home win of 2017 to move them up to 10th in the Premier League table, while 16th-placed Everton's woes continue and David Unsworth's chances of getting the manager's job on a permanent basis were dealt another big blow.
MEMORABLE MEETING November 2016 would not prove to be a welcome return to St Mary's for the now former Southampton and Everton boss Ronald Koeman.
That is despite the club spending nearly £150million during the summer transfer window to bring in the likes of Jordan Pickford, Michael Keane and Gylfi Sigurdsson.
"No matter what team David Unsworth picks at Everton they fail in every area", he told The Times.
"If it needs injured players to come back for things to get better, if it needs January to go and get new players, something has to change, because this group of players are underperforming, whether it is myself or Ronald in charge".
They have now won only once in seven games under Unsworth.
"I think we are in a tough moment, I think we have a massive week ahead of us".
Despite Southampton's attacking struggles at home - it has failed to score 10 times in league games at its St Mary's stadium in 2017 - it was able to create chances easily on this occasion.
Austin, who had not scored from open play since the victor in a 1-0 victory over Everton 364 days ago, was handed his first Premier League start of the season. If you ask me that question in a week, I might be able to give you a better answer. You have to be ready because you never know when the manager will need you to be ready.
