In series 1, 2 and 3 - there are many vehicles used by the actors for many story lines. In all of the first 3 seasons, several vehicles have been used with the same plate number BKW906. Series one - the blue Mazda that Loretta steals from the teachers car park at her speech evening. Series two - Again the plates were used on a blue Mazda, although this car belonged the Wests family friend Filane in series 2. In this series the plates were also used on Jethros lime green Holden - and in one episode the plates on this vehicle change from BKW906 in one scene to different plates several scenes later. Series three - In the episode where Van is befriended by Aaron Spiller and is out on the prowl to steal and 'chop' cars, the grey Mitsubishi Galant that them and Filane battle with to steal when it is hooked up to the tow truck, later having its rear axle ripped off with the tug of war also displays the plates BKW906. Again to series one - Cheryls Marroon Holden displays the plates ACTXXX....and in the subsequent series always displays the plates BSE177. Note - from series one and two the number plates on Vans Nissan Skyline change also. The only vehicles that remain with the same plates through out all series are Munters Mazda Bongo Van, Pascalles Nissan TRX and Wayne Judds four wheel drive.
In several of the first two series of 'OF', studio space can be seen above where the house ceiling should be. Mosty wide up-facing shots, but also in some scenes where the camera pans fast. 'OE' is filmed on a sound stage, not in the actual house shown as the exterior.
