The Mariners had their equal-worst A-League performance to date in the 2015–16 season. Their 13 points, the fewest in club history, resulted in a last-place finish, and they set a league record by losing 20 games while winning only 3, a record low for the Mariners. Central Coast allowed 70 goals, the most in league history, and had a goal difference of −37, the worst by an A-League team. The Mariners' totals of goals conceded at home and away (32 and 38 respectively) were also A-League records, and they went the entire season without a clean sheet.
