I didn't think much of the story, but I loved the reading. I listened to the whole thing just so I could keep listening to Amanda talk. If she could bottle her voice, I would buy a 50 gallon drum (whatever that means).
I did notice her accent is New Zealandish, but I'm sure it's difficult to find readers with every sort of accent in the world, and at least the accents are somewhat similar, better than having a Bronx accent or something. I did wonder what Bret and Jemaine would think though of their countrywoman masquerading as an Aussie. Then again, Jemaine did those Outback commercials, so he can't do much fingerpointing here.
I thought it was particularly fun to hear the New Zealand voice narrating an Australian imitating what may or may not be a Texan accent.
More than the wrong accent, I was bothered by the first person story being narrated by a narrator of the wrong sex. I kindof forgot the protag wasn't a woman until s/he nonchalantly lifted her/his shirt to show off the scars.
The story here wasn't bad, but I agree with others that it badly needs to be trimmed, to much repeating, too many similar events. At least 10 minutes could be trimmed off without cutting anything important, methinks.
And, another echo, it did seem like there was so much Aussie slang it was like the author was trying to prove their Aussie-ism. Especially the Vegamite metaphor. This was the exact same problem I had with Terry Pratchett's The Last Continent. In that one, rather than have any sort of coherent plot arc, it was just one a string of barely veiled cultural references and Rincewind running screaming from one to the next. As opposed to Interesting Times, which managed to work the cultural references into an actual plot.
