Phoenix won the Division Two title in 1989, and backed it up with success in the Knock-out cup, giving them a 'double'. In the early 1990s the club invested in building a new clubhouse, bar and changing room complex in the middle of the Wentworth Park complex. It was the catalyst for a period of major improvement. Junior development teams were highly successful, and dominated many of the age-groups of the Eastern Region Junior Soccer Association competitions. A new cohesion developed as players grew up playing together from a young age, and by 1994 the club had won the Knock-out cup once more. That side, under coach Darren Grainger, led a barnstorming year the following season, as they were crowned Division One winners. It was the club's first senior league success in twelve years. Phoenix also managed to claim the Division Two, and Division Four titles, as well as back-to-back KO Cups. 1996 did not bring league success, but the KO Cup and reserve KO cup were secured, and in 1997 they came second in Division One.
