FFA officials say Newcastle's clash with Sydney FC will proceed, as expected, at McDonald Jones Stadium on Friday night.
The W-League curtain-raiser between Newcastle and Adelaide, however, has been deferred from Friday until Saturday because of concerns about temperatures and bushfire smoke.
Jets officials were liaising with A-League management deep into Thursday night amid predictions that air-quality conditions will worsen on Friday.
The governing body released a statement on Thursday, which read: "At this time, the Hyundai A-League 2019-20 round-14 fixture between the Newcastle Jets and Sydney FC will go ahead as planned.
"The forecast ambient and Wet Bulb Globe Temperature for that match remain within acceptable ranges for the later kick-off and the air-quality forecast is improving with the arrival of a wind change to the north east on Friday.
"As Sydney FC are due to travel by bus up to Newcastle today, FFA was able to delay its decision on the Hyundai A-League Friday night match until this morning.
"In making decisions regarding whether a fixture will proceed, the safety, welfare and comfort of our players, match officials and fans remain our ongoing focus with regard to air quality issues as a result of these bushfires."
The game, scheduled to kick-off at 7.30pm, will be Newcastle's first after coach Ernie Merrick was sacked and replaced by caretaker Craig Deans.
The W-League game will now be played at McDonald Jones Stadium on Saturday, starting at 7.30pm.
"This decision was made last night due to the forecast of a combination of hazardous air quality and high temperatures in the Hunter region this Friday at the scheduled kick-off time of 5pm (AEDT) and was necessitated by Adelaide United's travel plans," FFA said.
