A young woman has allegedly been found with a massive stash of weapons including an automatic "machinegun" in her car at Sunbury.



Police were on patrol when they pulled over a car being driven by 23-year-old Bianca Micallef on Elizabeth Drive about 6.30pm on Tuesday.



When officers searched the vehicle, they allegedly found handguns, an automatic "machinegun" and ammunition, as well as machetes, a high-powered bow and a stun gun.

Ms Micallef faced an out of sessions hearing on Tuesday night.

She is due to face Broadmeadows Magistrates Court on Wednesday.
