After Chris gets to Linda's cottage, the cuts on his forehead come and go.
When the prison transport vehicle crashes, it comes to rest in the middle of the paved road. As the two convicts are seen walking away from it, it is now lying on the dirt shoulder of the road.
During one scene, a character describes shifting satellites in to 'Geo-synchronous Orbit behind the Earth' with an accompanying graphic on a computer screen - in simple terms, Geo-Synchronous means that the satellite rotates around the earth at a speed that keeps it locked over one location on the Earth's surface, the opposite to what they say they're doing.
A star's fate is dependent on its mass. The Sun simply does not have enough mass to become a supernova, which requires a mass at least 8 times that of the Sun.
They make reference to the serial killer being close to his execution date. However, Australia does not have the death penalty for any crime.
During the part where solar flares are blocking cellphone reception, the government decides to keep cellphone reception available by having a satellite providing it to one location. When the Earth spins around as it does every day, the cellphone reception would be blocked again by the solar flares.
Not only do the "scientists" repeatedly misread the formulas, but the most famous one makes a 22-orders-of-magnitude error in a calculation. Who ever heard of a scientist who wouldn't notice that and fix it immediately? That's like expecting an answer in the angstroms range and getting an answer in the light-years range!
During the looting scene, where a looter gets thrown through the store window, the glass shatters just before he hits it.
When the kidnapped scientists are forced into the helicopter, the opposite door is open for the viewer to see, but the camera equipment's shadow is clearly visible on the woman.
When Lisa Delgado suddenly pulls the Jeep (also containing Dr. Chris Richardson) over to the side of the road, the camera and crew are clearly reflected in the Jeep's doors.
The movie is set primarily in Australia, yet when the solar flare hits earth while the serial killer is being transferred, the impact is clearly over Africa.
90 minutes in there's a television report playing on TV in the kitchen. The report clearly tells us that the death row convict is in a maximum security prison in Pretoria, which is in South Africa, not Australia.
Number plates on the cars are not Australian.
When Prof Austin escapes to the beach hut in the Maldives, we see in the background a very large mountain. The Maldives are flat, with the highest point above sea level about 2.4 metres (8ft)
At least a part of the film is shot in South Africa. Tabel Mountain in Capetown is clearly visible in a number of scenes.
In an interview, one of the characters confirms that the Sun will go supernova and says this means it will expand and destroy the solar system. This is actually a closer description of what will happen when the Sun actually becomes a red giant. She should have said "explode" rather than "expand".
