In Australian crime novels, 'The Lost Man' often tells a tale of a person who vanishes under mysterious circumstances. It might explore the relationships between the people in the small Australian towns or the isolated areas. The story may involve the search for the lost man, which uncovers a web of lies, old grudges, and hidden motives. The Australian setting provides a unique backdrop, with its vast deserts, small-town politics, and the sense of isolation that can breed both desperation and secrecy.

I'm not certain about the main characters without more information about the 'the invisible man australian story'. However, likely the invisible man is a key character.

Or perhaps there are antagonists who are trying to use his invisibility for their own gain.
Perhaps the lost man is a detective who has lost his way, both literally and metaphorically. There might also be supporting characters like a local guide who tries to help him or an enemy who is causing his situation to worsen.

I'm not sure exactly, but likely there is the 'laser man' himself as the main antagonist. And there must be some sort of law enforcement characters like detectives trying to catch him.
Bill Barnacle is another main character. He has his own quirks and is an important part of the story as he interacts with the others in their adventures around the magic pudding. There is also Sam Sawnoff, who adds his own flavor to the story with his actions and decisions throughout the novels.
Australian crime novels often feature the unique Australian landscape as a backdrop. The outback, small towns, and coastal areas play important roles. They also tend to explore themes like isolation, community secrets, and the impact of the harsh environment on the characters.
In many Australian crime novels, the culprit could be a variety of characters, depending on the plot and the author's creativity.
