The quake hit at 2.55am, and sent shockwaves spanning the coast from Taree down to Wollongong, including Sydney.
More than 2700 people have reported feeling the quake to the Geoscience Australia website.
The quake struck 10km under the town of Singleton, west of Newcastle, and about 200km north of Sydney.
Geoscience Australia said it had an initial strength of 5.1 magnitude.
Thousands of Sydney residents across the city reported their homes rattling overnight, with most of the tremors felt in the suburb of Wentworth Point.
