UFO researcher Mary Rodwell says the Bundaberg region is following a global trend of increased sightings of the mysterious objects.

Ms Rodwell, who lives at Agnes Water, said she was receiving a lot of reports of sightings.

"A lot of people are wary of reporting sightings because of the ridicule factor," she said.

But she said sightings were being made by several people at once.

"Sometimes they may be witnessed by several members of the same family," she said.

"There have also been several sightings by people on fishing boats where they've all seen the same thing."

Ms Rodwell said it was impossible to say that all the UFOs spotted were not from Earth.

"We do know that some governments have aircraft that are of unusual shapes," she said.

Ms Rodwell said many people were reporting objects that were doing unusual manoeuvres, or winking in and out of sight.

"There may be two or three of them, and they may be changing colour," she said.

Ms Rodwell said right across the world there were some interesting sightings being made.

"The fascinating thing for us researchers is what does it mean, or does it mean anything?" she said.

Ms Rodwell said one of the things that seemed to attract UFOs was when intense events were occurring on Earth.

"Even around the time of the Fukushima nuclear reactor disaster there were a lot of photos of UFOs there," she said.

"It seems like they're monitoring what's going on on the planet."

Ms Rodwell said the consensus among UFO researchers was that whoever was in charge of the UFOs did not like people using nuclear warheads.

She also said Agnes Water attracted its fair share of sightings.

Rosedale was another place where UFOs had been seen.

"There have been some people who have reported 'missing time' on the road between Rosedale and Bundaberg, where the trip has taken a lot longer than expected," she said.

Ms Rodwell said there had also been an increase in sightings in New Zealand, which seemed to occur in conjunction with a series of small earthquakes that were shaking the North Island.
