Hi,
I've literally just discovered another Australian sci-fi adventure series for young people that was released as early as 2019!
The Unlisted is quite thrilling and dark, although has quite funny script writing. You can also see some wonderful sights of Sydney as well. I'm sure you can see it form the trailer:

I'm currently watching it on Netflix.
Let me know if you check this out too and what you think
