Lead author Dr Ryan Shannon, from Swinburne University of Technology, said it also the radio bursts travelled much further than from within our galaxy.
Scientists do not know what causes these mysterious radio waves or which galaxies they come from but say they must involve incredible energy, equivalent to the amount released by the sun over 80 years.
Co-author Jean-Pierre Macquart from Curtin University said the bursts travel for billions of years and occasionally pass through clouds of gas.
"Eventually, the burst reaches Earth with its spread of wavelengths arriving at the telescope at slightly different times, like swimmers at a finish line".
CSIRO's Keith Bannister, who engineered the systems that detected the bursts, told Morning Report scientists still did not know what caused them.
Researchers using a radio telescope in WA have detected 20 mysterious, powerful wave signals known as "fast radio bursts" in the past year - nearly double the number of unique signals detected worldwide since they were discovered in 2007.
"The telescope has a whopping field of view of 30 square degrees, 100 times larger than the full Moon", he said.
The team's next challenge is to pinpoint the locations of bursts on the sky.
"ASKAP is astoundingly good for this work".
The scientists in Western Australia, using the CSIRO radio telescope ASKAP (Australia Square Kilometre Array Pathfinder), recorded almost double the known number of fast radio bursts, or powerful flashes of radio waves, from across the universe.
"We'll be able to localise the bursts to better than a thousandth of a degree", Dr Shannon said.
The SKA could observe large numbers of fast radio bursts, giving astronomers a way to study the early Universe in detail.
