Two young BMX enthusiasts, P. J. and Goose, cross paths with Judy, Nicole Kidman, who is working as a trolley collector at the Warringah Mall during the school holidays in order to save up for her own bike. Their accidental crash with trolleys pushed by the local troublemaker the Creep gets Judy fired, setting off a chain of unlikely events that will pull three ordinary kids into a much larger plan.
The story begins after a successful Sydney bank robbery carried out by a crew wearing pig masks and armed with shotguns. The robbers’ leader, known as The Boss, outlines a bigger payroll heist slated for two days later, promising at least $1.5 million. He trusts his somewhat bumbling squad, led by Whitey and Moustache, to pull it off, with severe consequences for anyone who stumbles.
In the wake of the initial chaos, Judy, P. J., and Goose stumble upon a box of police-band walkie-talkies that the bank robbers hoped to use to monitor police activity. The trio, eager to fix their bikes and motivated by the thrill of a new venture, decide to sell the walkie-talkies to other kids in the area. Their discovery catches the attention of both the Bayside Police, who can hear the kids chatter on the airwaves, and the criminals, who quickly realize who has taken the box.
A nocturnal chase unfolds when Whitey and Moustache, wearing monster masks—“going formal,” as described by Whitey—spot the trio and pursue them through a cemetery. The kids narrowly escape, a tense return to normalcy that is short-lived as they keep dodging further encounters with the robbers. Judy is recaptured the next day while trying to procure another walkie-talkie for The Creep, but she escapes with the support of P. J. and Goose.
What follows is a cinematic, cartoonish clash across Sydney’s landmarks. The chase weaves through the harbor and culminates in a memorable sequence down the Manly Waterworks water slides, all while the kids ride their BMX bikes and stay one step ahead of their pursuers. The trio, now united by their shared goal and resourcefulness, are eventually captured but manage a dramatic escape from police custody.
With help from the local kids, they pivot from fear to strategy and orchestrate a plan to thwart the payroll robbery. Using the walkie-talkies to triangulate the meeting point, they set up an ambush that results in the capture of The Boss, Whitey, and Moustache. Judy is held hostage in the getaway truck, but the two boys pursue, causing a crash that brings police intervention and a successful arrest.
In a celebratory epilogue, the police establish a BMX track as a token of gratitude for the arrest, and in the track’s inaugural gathering, the BMX Bandits sweep the major awards, sealing a feel-good ending built on ingenuity, courage, and teamwork. The film folds humor, adventure, and a sense of community into a vivid, kid-centered caper that remains faithful to its lighthearted spirit while delivering a memorable urban treasure hunt across Sydney.
