When Paula goes out with her children, she's "always on the lookout for people".
As a Senior Digital Forensic Examiner for the Australian Federal Police, the 35-year-old mother-of-three spends her days combing through evidence to help take down child exploitation rings.
"You see material that I don't think anyone should see," she tells Mamamia.
"There will be jobs that will always affect you and it will play on your mind. I am human and I am a mother."
After 12 years on the job, it’s easy to understand her concerns. But she’s thankful her husband offers a different perspective.
"My husband has been really good in reminding me that not everyone is a paedophile."
"He’s helped me to [understand] you can be cautious but there is a line between being overly paranoid and letting the kids be kids."
Despite the challenges of the job, the payoff of helping a child in need makes it all worth it.
"I look at the bigger picture and know if I give it my all then something will come out of it, and a child somewhere may be better off."
Her desire to help people and make a difference was what inspired Paula - a self-described "computer geek" - to join the AFP in the first place.
That, and Law and Order: SVU.
