The F3 Derby is set to go ahead, despite torrential rain in Newcastle.
The decision followed a pitch inspection at 10am. A second inspection is due at 2.30pm, 90 minutes before kick off.
FFA head of leagues Greg O'Rourke said the match between the Newcastle Jets and Central Coast Mariners, set to be played at McDonald Jones Stadium on Sunday at 4pm, "will currently go ahead as scheduled".
Mr O'Rourke said the playing surface had "held up well over the weekend and is suitable for the match to be played".
"Based on the condition of the field of play and the prevailing weather conditions in the area, we are currently able to proceed with the match as scheduled," he said.
"We will formally reinspect the pitch at 2.30pm. Given the current conditions in the Sydney basin, if that weather was to move north and the weather conditions in the Hunter Region deteriorate, we would need to reassess.
"As such, to be prudent, a second inspection has been formally arranged for that time."
