Journalism, television, and radio
Kruszelnicki wrote and presented the first series of Quantum in 1985. He writes a weekly column for The Age and the Sydney Morning Herald newspapers on scientific "mythconceptions". His radio work includes a weekly science talkback show on Triple J which attracts up to 300,000 listeners and is available as a podcast. He often helps with other science and education Triple J promotions, such as the Sleek Geek Week roadshow with Adam Spencer and Caroline Pegram.
He has had cameo appearances in a number of television series including Pizza (screened on SBS) and Neighbours. In the Neighbours episode, he was confused with the Dr Karl character of that series. From early 2008 onward he co-hosted a TV series of Sleek Geeks with Adam Spencer.
In 1994 at the Michael Daley Awards for Science, Technology and Engineering Journalism, Kruszelnicki won the awards for Best Entry (print or broadcast) relating to the topic “Remote Sensing”, the field of the 1995 Australia Prize, Best Radio Entry (news, feature or documentary) for “Tsunamis” and “Science Talkback” (joint award, shared with Elizabeth Finkel of Ockham’s Razor).
In 2014, Readers Digest readers voted Kruszelnicki as the ninth most trusted person in Australia
As of late-2013, Kruszelnicki has written 33 books, along with numerous lecture series (using material that often ends up in his books, or vice versa). Some of these lecture series and books have been televised for events such as Science Week, with him supplying voice overs and sometimes appearing in claymation.
