A late Matt Jones header handed Fareham a 2-1 derby victory over Horndean at Cams Alders.
The hosts were second best for much of the match, with Dan Hayes putting the Deans in front.
But Doug Rowe levelled for Fareham before Jones popped up with the winner in the closing stages.
Fareham, wearing their new home kit matching the colours of AC Milan, struggled in the opening half and were lucky to go in goalless.
They were left to question the referee’s decision-making, too, as Gavin Spurway received only a talking to after a two-footed challenge on James Roden.
On 55 minutes, Horndean shook things up by taking a deserved lead thanks to a defence-splitting past from Chamal Fenelon that presented Hayes the easiest of chances to beat Luke Douglas from close range.
In a rare foray into the Horndean half of the pitch, Fareham’s Danny Thompson was denied an equaliser by keeper Derek Harding.
The hosts were then relieved when Fenelon went clear but fired wide.
In an effort to add the killer instinct to his lacklustre strikeforce, Fareham boss Matt Patt brought on Graham Lindsey and Ashley Tattersall.
But it took until the final few minutes for the hosts to threaten when the best move of the match ripped open the Horndean rearguard and Austin’s superb cross was turned in by Rowe for the leveller.
Then, with seconds left before the final whistle, Fareham turned the game on its head when skipper Jones got on the end of a Thompson free-kick to head the winner.
