Ms Al-Shamahi has mentioned Australia briefly a couple of times but I suspect that that might be the extent of the Australian connection in these five episodes. (FYI, Sandra: The most recent episode is repeated on Saturday arvo and Tuesday morning, and the next new ep is Tuesday night.)
The interesting thing about the last episode I saw was that an area of Indonesia was investigated and the date of human occupation was similar to the estimated time of Australia's first people arriving.
