The third generation was also 'remanufactured' in Australia by HSV (Holden Special Vehicles) from 2001 to 2006, marketed in a range of HSV-badged high performance derivatives without application of the Monaro nameplate.

Norm Beechey drove a HK Monaro GTS327 to third place in the 1969 Australian Touring Car Championship, the first time the ATCC was held as a series rather than a single race.

As the Monaro was Holden's main car in Series Production racing, this was primarily in response to Ford who had introduced the XW Falcon GTHO Phase I in 1969.

The HT Monaro can be distinguished from the HK by the adoption of plastic grilles (previously metal), two section taillights separated by a blacked out panel, a round speedometer instead of "strip" style allowing for bringing the tachometer into the main instrument cluster instead of on the floor console, rubber front suspension bushes instead of the HK's sintered bronze, and larger taillights where the turn indicators also wrapped around the now slightly undercut edges.

The HDT entered three Monaros in the 1969 Hardie-Ferodo 500 the lead car driven by Colin Bond and Tony Roberts winning from 1968 winners Bruce McPhee and Barry Mulholland who had switched to driving a Falcon GTHO.

In January 1970, Bond and Roberts would win the Rothmans 12 Hour Series Production race at Surfers Paradise driving their HDT Holden Monaro.

Beechey's win was all the more remarkable considering he failed to finish at Warwick Farm and did not start the final round at Symmons Plains after suffering an engine failure in qualifying.

The "GTS 350" models no longer had the 350 Chevrolet badge on the fender, but rather a bold decal stating "350" as well as blackout treatment that covered the air-vents on the bonnet.

[5]: 65 A completely new body design emerged with the HQ series in July 1971, including the new Monaro 'LS' (commonly believed to mean "Luxury Sports") model which featured four headlights and chrome trim rings shared with the Holden Premier sedan.

The continued erosion of the GTS350 cachet was compounded by the deletion of specific "350" decals on the post-1973 cars, with all Monaro GTS coupés and sedans now being externally labelled with the generic HQ series 'V8' bootlid badge.

[12] The LE was an amalgam of prestige and surplus parts (including an eight-track cartridge player well after cassette tapes were common), in effect a combination of Monaro GTS and Statesman Caprice components.

[14] Released on 5 October 1977,[5]: 169  this HZ variant featured a four headlight grille, front and rear air dams, four-wheel disc brakes, sports wheels and a 4.2-litre V8 engine as standard equipment.

[5]: 169 Ultimately, the VB Commodore proved very popular in both six-cylinder and V8 forms, such that all full-size HZ Holden passenger cars were phased out of production in 1980.

[15] A Series 2 model debuted in December 2002 with a revised dashboard from the VY-series, a new alloy road wheel design and new paint and trim colour choices.

Other unique features of the 2004 CV8-R cars included 18" five-spoke machined face alloy wheels, smoked front and rear lamp treatment, and a “Holden By Design” electric sunroof.

[18] The revised rear bumper, dual exhaust system, and new hood with air intakes would soon find their way onto the export Pontiac GTO.

However, in July 2005, Holden announced that production of the current generation VZ Monaro CV8 would soon be coming to an end and this led to the run of a special edition model called the CV8-Z, of which 1,605 units were ultimately made.

The last Holden Monaro-badged coupé was purchased by Emerald, Queensland businessman Darryl Mattingley for A$187,355.55—around three times the normal retail price, on 19 February 2006.

[18][20] The Monaro was used as a basis for various concept cars and was used by several different brands, HSV in Australia, Chevrolet in the Middle East, Pontiac in North America, and Vauxhall Motors in the United Kingdom.

[26] Conjecture surrounds the total number of Coupé4s built, claimed to be 134 units (28 Series III models; 106 VZ; 6 pilot cars) of which 20 were exported to New Zealand[5] available only in Phantom Black, Quicksilver and Sting Red.

[24] In line with the announcement made by Holden in July 2005 about the Monaro's end of production, HSV again released a GTO LE from April 2006 (featuring three body colour and stripe combinations for just 50 units in black, 25 in yellow and 25 in red) plus a final 'Signature' limited edition.

[24] This signature model retailed for A$83,990 plus on road costs when new and gained HSV's top-of-the-line AP racing brake package with coloured front six-piston calipers with 362mm cross-drilled and grooved rotors and rear four-piston calipers with 343mm cross-drilled and grooved rotors, 19 inch multi-spoke rims (found on the HSV GTS-R Coupe concept car) sunroof and unique paint scheme as standard.

[27] Just like HSV, independent manufacturer Corsa Specialised Vehicles (CSV) also produced its own version of the Monaro, badged the Mondo ("world" in Italian) and based on V2 series.

It was also sold, in left-hand drive, in the Middle East as the Chevrolet Lumina Coupé, and in the United States as the Pontiac GTO, reviving another classic muscle car icon.

A Harrop supercharger was installed onto the standard GM 6.0 L LS2 engine by Vauxhall dealer Greens of Rainham[33] in conjunction with tuning firm Wortec,[34] increasing power to 373 kW (500 hp) and torque to 677 N·m (500 lbf·ft).

The possibility briefly existed in the early 1980s for a revival of the Monaro badge based on a combination of the Holden VH Commodore and the Opel Monza.

With serious exploration of the concept, a Monza was shipped to Australia by Peter Brock but the project was shelved as Holden was more preoccupied, at the time, with engineering work to revamp the Statesman and Gemini range as well as with the launch of the JB Camira.

The Holden Monaro four-seater convertible, codenamed Marilyn, was a fully operational one-off concept car, it was never intended to reach production.

It remained only a rendering with no production prospects, thanks to the existence, at that time, of the larger volume selling fifth-generation Chevrolet Camaro, which was based on the same Zeta platform of the VE-VF Commodore.

In fact, the first GRM-built car in 'nuclear banana' yellow underwent shakedown laps at Calder Park before a half day's testing at Winton wearing the race number "427".
