Released in August 2004, the VZ series was a minor facelift of the previous VY series that featured a new V6 engine in different tune guises. The powerplants included 175 and 190 kW (235 and 255 hp), 3.6-litre Alloytec V6 engines in place of the older 3.8-litre Ecotec V6. Other changes to the V6 was the loss of the supercharger that was included in the S models The VZ Commodore was available in several model variations, most of which carried over from the VY range, with the exception of the newly introduced SV6, a specification level that replaced the S range. All models in the Commodore range (Executive, Acclaim, Berlina, Calais, SV6, SV8 and SS) were available as sedans. The advanced 3.6-litre Alloytec engines were more powerful, responsive and fuel-efficient than the outgoing Ecotec V6. To achieve 190 kW (255 hp), the Alloytec V6 gains variable valve timing on both inlet and exhaust sides as well as a dual stage intake manifold, while the 175 kW (235 hp) version retains variable valve timing on the inlet side only. Sales of the VZ series failed to match those of the preceding VY in light of rising small car sales, higher fuel prices and growing interest in the whole new replacement, the VE series. Selected models bring advanced active safety features that electronically assist the driver to maintain vehicle control in emergency situations.

The Forests Commission developed the use of helicopters for aerial ignition from the mid 1960s. Bryant and May at Richmond worked with the Commission to develop a Delayed Action Incendiary Device. DAIDs as the were known, had an overall length of 180 mm, striker end length - 10 mm. Ignition end length - 80 mm, then a layer of high melting point wax (to prevent accidental ignition when rubbing together in transit). Both ends coated with a modified match head compound with safety fuse exposed length between coated match ends. There was a 17-second delay from when the small end was struck to an intense flaming of the large end, which lasted for 40 seconds. DAIDs were dangerous so were stored in a metal box outside the helicopter along with a disposable striker patch attached with a quick release pin to a special half-door. The first test was with a Bell 47G on 4 October 1967 and the first use, anywhere in the world, of DAIDs to backburn a large bushfire was undertaken in north eastern Victoria in February 1968. There was a crash of an FCV helicopter conducting aerial ignition near Wandiligong on 19 April 1978 with the tragic death of two forest officers and their pilot. The crash led to the immediate end of the use of DAIDs and the adoption of the safer Premo ping-pong ball incendiary machine which originally came from Canada but was modified at the Altona workshops. Overall, the development of aerial ignition techniques by the Forests Commission from the mid-1960s resulted in a steady climb in the area burnt each year…. peaking at 477,000 ha in 1980-81 and with an impressive 10-year rolling average of 220,000 ha around the time of 1983 Ash Wednesday Bushfires.Developed in Victoria for aerial ignition by the FCV and Byant & MayLarge double ended match used for aerial ignition and back burning by dropping from a helicopterforests commission victoria (fcv), bushfire, planned burning
