The reason I included those inaccuracies though, were because I wanted Michael to be a character that doesn't tell the reader what the author thinks, but what he thinks as a character. If the reader knew what the character thought was right 100% of the time, it would be dreadfully dull, and if every fact he knew was 100% correct, it would also be incredibly dull. And yes some of the things described aren't the perfect and accurate representation of Australia, especially the Outback.
And nobody has ever associated 'Australia' with 'superpower' (I found this so odd that it was what captured my attention for the rest of the piece, as I honestly assumed I was going to be reading a weird SCP-universe alternate history where Australia was a superpower).
And I honestly thought Australia was a superpower in terms of it's place right now, but upon further research I did find out it wasn't. However, I found this after the tale was published, and honestly I think it fits in terms of Micheal biases and beliefs.
I can understand that these can turn someone off, and I can respect that, especially with the tone, which doesn't fit in the horror aspect when looked at. I mean, if I heard someone was attacked by kangaroos I would laugh my ass off. Also, I will tell you that Micheal is Australian, and from me talking to friends and whatnot, most actually haven't seen kangaroos before, in the desert or otherwise, so I based it off that.
Last thing, yes I do have a problem with some grammar, especially with word order or placement. When I got feedback, most of them didn't see any problems, and those that did I quickly fixed (I once wrote a sentence backwards in this, I'm that bad.).
Anyway, with that, I do thank you for spending your time writing out what you thought about it, it really helps me when developing the next chapter in this series.
