The suburbs around Gosford, on the Central Coast, are the state's biggest hot spot when it comes to UFO sightings, with dozens of seemingly authentic cases reported every year.
Each month, as many as 30 people turn up to meetings to share their UFO experiences.
UFO Research NSW secretary Joann Kanda, who helps organise the meetings, saw what she believed was a UFO near her home at The Entrance in the mid-1990s.
"It was just a sort of a glowing light in the middle of the night," she said.
"The dogs made a strange noise and I got up. There was something up in the sky with a greenish glow."
The region was the scene for one of Australia's most baffling UFO cases - a series of sightings in 1995 and 1996 - that were reported by police and many other credible witnesses.
Residents have told of seeing shiny, spherical, illuminated UFOs that often hovered above water.
UFO Research NSW's Doug Moffett said UFOs were commonly spotted over water or near power plants and the Central Coast had plenty of both.
The geography of the Central Coast may also play a part. It is heavily populated in parts, which means there are people around to spot UFOs, but still isolated enough for them to be visible in the night sky.
"What UFOs do is, largely speaking, covert in nature. They're obviously not landing at the steps of the Opera House and saying, 'Take me to your leader'," Mr Moffett said.
The UFO and Paranormal Research Society of NSW said the Blue Mountains also figured heavily in UFO sighting reports.
A group of enthusiasts spent the weekend in the mountains searching for UFOs they say visit the area each year in the last week of March.
One of the group, who declined to be named, said that in past years the craft had appeared above the Burragorang Valley, beyond Jenolan Caves, and were seen to hover for some time.
Several readers have reported seeing UFOs near Wollongong a week ago.
