An estimated 30-40 homes at Lilli Pilli have been without power since Sunday's extreme weather.
At the same time, thousands of other residents in the adjoining suburbs of Burraneer, Caringbah, Caringbah South, Cronulla and Woolooware were blacked out for an anticipated shorter duration on Thursday afternoon.
The power for these homes went out about 3pm and is expected to be restored by 5.30pm.
The five-day Lilli Pilli outage was caused by a falling tree damaging a power pole.
Residents say they are totally frustrated by Ausgrid's failure, and apparent lack of interest. in restoring power to the area.
Callers to Ausgrid have been told there is a record of 12 residents reporting an outage but "no job number" for work to be done.
One of the affected residents, Greg Sharp, said it appeared the Lilli Pilli area had been "dropped to the bottom of the list".
"Ausgrid only seem interested if they are told power lines are down," he said.
"Out of frustration, I told them yesterday that was the case so three men and a cherry picker arrived this morning and inspected the pole, but left quickly and haven't been back," he said.
"It was an absolute waste of manpower them turning up and doing nothing."
Mr Sharp said, "In the meantime, we are burning candles and going up the shop at night to buy ice".
