Film adaptation of the first book of ''Literature/TheTomorrowSeries'' by John Marsden.
----
!!This film provides examples of:
* AbandonedPlayground: The scene of [[spoiler:Robyn's]] shootout near the bridge at the climax of the movie.
* AdaptationDecay: {{Lampshaded}} - Corrie is reading a book, and when Ellie asks what she thinks of it, she replies, "Better than the movie." Ellie comments in response, "Books usually are."
* AdaptationDistillation: The movie itself, which retains the action sequences but keeps the book's focus on character development.
* AerosolFlamethrower: Lee uses one to get the cattle stampeded.
* ApocalypticLog [=/=] BookEnds: Ellie talking into a camera recording. She also serves as TheNarrator.
* BaldOfEvil: The soldier who executes an angry prisoner.
* BerserkButton: Ellie ''really'' rips Chris a new one, [[spoiler:and actually threatens to shoot him]] when she finds he's fallen asleep on watch.
* BlackComedy: Chris's stoned description of finding his neighbors, including their infant daughter, shot dead in their car CrossesTheLineTwice.
* CaptainObvious:
--> '''Robyn''': You're bleeding!
* CarChase: Garbage truck vs. M60-equipped Fast Attack Vehicle. Truck = 2, FAV = 0.
* CarFu: One of the [=FAVs=] mentioned above first gets tangled in electric cables, then hit so hard by Ellie's garbage truck that it gets smashed into the second floor of a nearby building.
* CellPhonesAreUseless: Kevin draws attention to the fact that there's no cellphone reception in Hell as it's too isolated early on. When they return to town to discover that it's largely abandoned, they all check their cell phones in unison, only to discover that they still cannot get reception (presumably as the invading army knocked out the towers). This explains away why no one tried to contact them via phone to warn them, and why they don't use their phones to stay in contact later when they have to split up. The book on which it is based was written before cell phones became so ubiquitous among teenagers.
* ComicRelief: Although the situation invariably stays grim no matter what he says, Homer's constant joking and snarky attitude occasionally helps to take the edge off the worst horrors.
* ConcealmentEqualsCover: The two girls driving the garbage truck are ''partially'' protected by the front scoop (though not the windshield) and heavy steel rubbish container, but there are several moments when they're being shot at from the sides by auto-rifles and medium machine guns. Averted on the occasion when one of them drops a roller door only for several bullets to punch through (she's already ducked out of the way).
* ContemplateOurNavels: Ellie and Corrie sit in their old playhouse and muse about how they've lost their innocence and nothing will ever be the same.
* DeadpanSnarker: Everyone has their moments, but Ellie and Homer take the cake. There are scenes where the two of them practically run on nothing but SarcasmMode.
* DeathFromAbove: Foreshadowed when Lee insists they park the Land Rover under cover rather than leaving it out in the open.
* DirtyCoward: When Ellie and Corrie get pinned down by automatic fire during their first contact with the enemy soldiers, Kevin takes a moment to stare in horror before he hightails it out of there. [[spoiler:He returns barely a minute later, but still, Corrie is deeply hurt by this action of his. In the end he redeems himself when he surrenders to the Coalition together with her after she's been shot.]]
* DistractedByTheSexy: Homer gets tackled while he's staring at Fi taking off her shirt to reveal her bikini.
* DrJerk: The dentist who treats Lee's bullet wound is jumpy, abrasive and anything but subtle with his words, but considering the situation he's in and the risk he's taking, it's probably justified.
* DumbBlonde: Fi
* EveryCarIsAPinto: Somewhat justified when they open the gas tank first. On other occasions...
* EveryoneOwnsAMac: The only computer we get a good look at is farm girl Ellie's Macbook.
* FanService: The whole cast consist almost entirely of ridiculously beautiful young people. All the boys get their WalkingShirtlessScene, Fi gets a gorgeous slow-mo shot to reveal her red bikini, and neither Ellie nor Corrie are shy about flaunting their incredible looks. Ellie even explicitly assures Fi she's beautiful when the latter reveals how she's never had a boyfriend to date.
* GoodGunsBadGuns [=/=] ImproperlyPlacedFirearms: The Coalition mooks carry [=AK47's=], unlike in the novels. Yet they also have American Fast Attack Vehicles and Kevlar helmets with {{samurai}}-like headpieces.
* HalfwayPlotSwitch: There's no lie involved that it's a movie about an invasion of Australia, but the "Teens going camping" part goes on long enough you start to forget what the movie's eventually about.
* HardToLightFire: The two girls who drive the tanker-truck and prepare the petrol-soaked rope to blow up the bridge both thought the ''other'' girl brought the lighter.
* HeroicBSOD: Poor Robyn. Ellie also breaks down when [[spoiler:Corrie is shot and they have to retreat without her and Kevin.]]
* JustPlaneWrong: A minor case of it compared to the egregious examples in the books. The enemy fighters look like the fuselage of an F-16 with the wings of a Mirage III-O grafted to it.
** They may have been [[http://en.wikipedia.org/wiki/Chengdu_J-10 Chinese J-10s]], which have features from both craft (Delta wings, chin intake, single engine). The J-10 would fit with the distinctly modern PLA design of the enemy uniforms.
** The aircraft actually resembles the Chinese/Pakistani [[http://en.wikipedia.org/wiki/JF-17 JF-17 Thunder]].
** Furthermore, the enemy helicopter is a Robinson R44, arguably the least threatening civilian helicopter out there.
*** It's not just the planes, either: when a enemy fighter launches a missile, it's fuselage is red. Training missiles are red, but a real one would still be gray steel.
* KillItWithFire: Ellie improvises a fire-bomb from a gas canister to use against persuing soldiers. It works awesomely.
* LadiesAndGerms / MyFriendsAndZoidberg
-->'''Ellie''': Ladies and gentlemen...\\
''Homer belches.''\\
'''Ellie''': ...and Homer...
* LockAndLoadMontage: The original low-key ending was replaced by the group taking captured weapons out of a crate, strapping them on and standing against the skyline in defiant poses.
* MadeOfExplodium: Amazingly enough, even worse in the movie than the books. The ''bridge itself'' explodes after the tanker truck has.
* MoralDissonance: Ellie rips Chris a new one for falling asleep on watch, which risked all of their lives, and tells him to shape up and be more responsible. Later, Ellie and Fi [[spoiler:accidentally turn off the radio, talk about boys instead of keeping watch, and both forgot to bring the lighter to set off the petrol-tanker bomb. This nearly gets them both killed, forces Robyn to break her pacifist vow, and gets Corrie shot.]]
* MoreDakka: At least a dozen automatic weapons open fire on Ellie within moments of her being discovered by a sentry when the group scouts out the concentration camp. The hail of bullets results in a lot of StuffBlowingUp.
* MyGodWhatHaveIDone: Most of the cast members have this reaction when they're forced to kill someone for the first time. NiceGirl Robyn probably gets it worst due to her Christian pacifist vow.
* NotSoDifferent: When Ellie scores her first desperate kills with her makeshift gas canister bomb, she notes that the scorched soldier lying before her must've been about her age, and it's quite likely she was no more willing to fight this war than Ellie is.
* PrettyLittleHeadshots: Averted. When the angry prisoner gets [[BoomHeadshot shot dead]], the bullet visibly blows his brains out the back of his skull.
* SceneryPorn
* ShirtlessScene: Every male cast member at Hell.
* ShoutOut: Homer at one point reenacts Gandalf's famous "You shall not pass!" scene from ''Film/TheLordOfTheRings''.
* SprayAndPray: Averted when Homer (who's used to firearms) fires just a couple of aimed shots at the helicopter from their captured [=AK47=]. Later when the inexperienced Robyn fires she empties the magazine.
* TheStoner: Chris.
* TemptingFate: Ellie clearly brings upon the entire invasion by asking her parents what could possibly happen while they're away camping.
* TooDumbToLive: Kevin almost bites it and risks the lives of the entire group when he runs back for his dog while an airstrike on his position is imminent.
* TookALevelInBadass: Most of the cast goes from innocent teenagers to hardened guerilla fighters over the course of the movie.
* ViewerFriendlyInterface: The text messages that Corrie sends Ellie on her mobile phone appear in large, easy-to-read text, as does the "out of service" message.
* WeNeedADistraction: The cattle stampede.
* YellowPeril: The invaders, though belonging to no obvious country (in fact a coalition in the movie), appear to be Asian in origin. Probably justified, despite any UnfortunateImplications, given the proximity of Australia to East Asia and thus the likely source of any invasion.
* YouthIsWastedOnTheDumb: Being teenagers who have never experienced danger before, some of the kids make some foolhardy mistakes.
** For example, a risky mission to blow up a heavily guarded bridge is really ''not'' the time to gossip about boys.
* ZergRush: A radio broadcast mentions that the Coalition invaded Australia with about half a million men they landed via cargo planes and ships. For comparison: the Australian military numbers less than 60,000 active troops. It's not entirely clear how those fared against the invaders, but the fact that the Coalition has troops to spare for seizing the protagonists' small rural hometown hints at a CurbStompBattle against Australia.
