What Richiev and DPG said.
Also as a side note there are too many vague or generic descriptions in this logline:
"...bitter war?" - nuclear, chemical warfare, all out invasion, etc?
"...mysterious creatures?" - mysterious in what way? Do they have special powers? Highly superior technology and weapons?
"...mysterious aboriginal?" - similar to the above, mysterious in what way? What makes him mysterious? Is there a reason for the child to be a boy not a girl if so why?
"...grim reality that the war is far from over?" - is the war still being waged in a far away land from Australia? Is there a cease fire and the enemy is planning a sneak attack? Is the war out of sight for most people?
Hope this helps.
