Because the 27-year-old daughter-in-law of Campaspe Shire’s Cr Leanne Pentreath is anything but dumb.
But the Bendigo police officer is using the cliche to her advantage, to be underestimated by her opponents and fly under the radar.
"I told everyone I was a hairdresser, not a police officer so I would fly under the radar and not stand out," she said.
"It seemed to work because no-one questioned it."
Hannah is one of 24 contestants on this year’s Australian Survivor: Champions versus Contenders, which premiered on Wednesday, July 24, on Channel 10.
She decided to audition after her husband Zac Pentreath, a former Lockington resident, applied.
"I got on and he didn’t so he’s pretty jealous," she laughed.
Hannah arrived home two months ago after filming in Fiji.
And while she’s been in the force for four years and is used to being out of her comfort zone and pushed to her limits, Hannah said the experience was unlike anything she’d ever experienced.
"It was definitely challenging and cold at night," she said.
"Probably the most challenging was not being able to phone my Mum because I call her constantly, so that was hard for me. I really missed my husband too. Especially when I had a hard day and needed to de-brief."
The food or lack of was also hard to take; losing about 5kg in the process.
"I’m sick of rice," she laughed.
"It’s challenging living without food. I was exhausted a lot of the time.
"Apart from that, it was an amazing experience, unlike anything I’ve done before. It’s strange waking up on an island not knowing the time and having no access to a phone or technology. When my phone was handed back to me, I didn’t even recognise it."
But she didn’t miss her phone as much as she did a shower.
"It was so nice to be able to wash my hair. It was disgusting," she said.
"It took two weeks to get all the dirt off me because it was so caked on."
Having watched two episodes so far, Hannah said she was happy with how she had been portrayed so far.
"It’s strange seeing yourself on TV," she said.
"Zac’s loved it. We both knew it would be funny to watch but it is what it is. It’s a fun experience to share with him."
And the $500,000 prize money would just be the icing on the cake.
"It would change our lives," Hannah said.
"But it’s not just about the money. It’s about making it that far and the achievement of outlasting 23 other people in those conditions."
