Top 5 Auctions This Week in Australia

15 September 2026 edition · AutoMarkets

A 7.0-litre Corvette Z06, a V10 Lamborghini Gallardo, a modified Hakosuka Skyline, a VN SS Group A and a restored early Porsche 911 S: this week's Australian car auction picks cover five very different approaches to an enthusiast car.

Each has a reason to look beyond the headline. The Corvette brings substantial modifications and a right-hand-drive conversion. The Gallardo offers early V10 character with documented servicing. The Skyline combines classic Japanese styling with a larger engine, while the Holden and Porsche put provenance and restoration quality at the centre of the conversation.

Here are our top five auctions to follow this week in Australia, with the specifications that matter and relevant recorded sales from AutoMarkets.

This week's featured car auctions

These are this week's featured auctions; their closing dates extend beyond the current week. Dates and listing details were checked on 15 September 2026. Follow each listing for the latest auction status and exact closing time. Odometer figures are indicated readings, not independently verified lifetime distances.

1. 2007 Chevrolet Corvette C6 Z06: 7.0-litre LS7 power with a manual gearbox

The C6 Z06's appeal starts with its naturally aspirated 7.0-litre LS7 V8, six-speed manual gearbox and rear-wheel drive. Its aluminium chassis, dry-sump lubrication and carbon-fibre front guards give it engineering substance to match the wide bodywork. For buyers drawn to large-capacity American performance, that combination remains a compelling reason to explore a Corvette C6 Z06 for sale in Australia.

This black example in Melton shows 34,152 km and has been with its current owner for approximately 14 years. Converted to right-hand drive, it carries a custom leather-and-suede interior, replacement sports seats, 360 Forged wheels and a Borla exhaust. The Trading Garage description reports work to the camshaft, lifters, timing chain, valves and valve springs, plus a replacement clutch. An intermittent airbag warning light is also disclosed. Those details make the conversion and mechanical-work records central to assessing this particular car. View the featured Corvette and auction details.

Corvette C6 Z06 market context in Australia

AutoMarkets records a 2006 right-hand-drive Z06 with 23,999 km selling for $135,000 on 15 June 2026. That is a useful recent Australian reference for the same generation and variant. The featured car's mileage, modifications and conversion history still need to be assessed individually. See the recorded 2006 Z06 sale.

The broader Corvette C6 Z06 market page also includes a 427 convertible result. We have kept that separate here because the different body and specification make it a weaker comparison for this coupe. One closely related sale provides a reference point, rather than an established price range for every Z06.

2. 2004 Lamborghini Gallardo: an early V10 coupe with E-Gear

The first-generation Gallardo put a naturally aspirated 5.0-litre V10 and all-wheel drive into Lamborghini's more compact supercar. This 2004 example uses the six-speed E-Gear automated manual transmission, so gearbox specification should be part of any comparison with other Gallardos.

Finished in Nero Pegaso, the North Melbourne car indicates 37,750 km. It was originally delivered to Hong Kong before being imported to Australia, and the auction description records Lamborghini and specialist servicing across both markets. Recent work is listed at 37,475 km in January 2026. A clutch report from 2023 recorded approximately 40% wear at that time; a current readout would provide a more useful assessment today. The seller also discloses some interior-trim faults, making the detailed photographs and service paperwork worth reviewing together. Explore the featured 2004 Lamborghini Gallardo.

Lamborghini Gallardo prices: what AutoMarkets records

The early Gallardo Coupe market contains six recorded sales, ranging from $106,000 to $140,100, with an average of $128,933 at the time of writing. The sample spans different years, mileages and transmissions, so the average is historical context rather than a valuation of this car.

A more recent reference is a 2004 automatic Gallardo with 72,436 km, recorded sold for $122,500 on 16 January 2026. The featured example shows fewer kilometres, but delivery history, clutch condition, servicing and overall presentation remain part of the comparison. Its closing result will add another Australian data point for early V10 Gallardos.

3. 1970 Nissan Skyline 2000 GT: a modified Hakosuka with a 2.8-litre six

The C10-generation Skyline, widely known as the Hakosuka, brings a different kind of appeal to this week's classic car auctions. Its upright shape and early Skyline heritage make it immediately recognisable, while this example's modifications give it a distinctly enthusiast-led character.

The 2000 GT badge describes the original model: this car now runs an upgraded 2.8-litre straight-six with triple Mikuni carburettors and a manual transmission. Watanabe wheels, flared arches, front coilovers and upgraded front brakes complete the package. It is offered as a modified 2000 GT, so its identity and specification should guide comparisons with other early Skylines.

Trading Garage describes a restoration undertaken in Japan before importation, with the current owner having acquired the car approximately six years ago. Maintenance records since 2021 accompany it, including fuel-system and ignition work. The odometer indicates 21,532 km. Disclosed faults include an inoperative oil-pressure gauge, clock and original radio. See the 1970 Nissan Skyline 2000 GT listing.

Hakosuka Skyline market context

AutoMarkets does not currently display a dedicated C10 2000 GT sold-data sample in its market index. The broader Skyline results cover substantially different generations and specifications, so they do not establish a defensible price range for this car.

For this auction, the useful questions concern the quality of the Japanese restoration, the body and underside, the documentation for the engine upgrade, and how well the modifications work together. Original GT-R results would require a separate comparison. This auction is worth following as a potential Australian reference for a modified Hakosuka 2000 GT, with its final outcome more informative than an early bid.

4. 1990 Holden HSV Commodore VN SS Group A: Australian homologation heritage

The VN SS Group A has a specific place in Holden's performance history. Developed for touring-car homologation, it combined a substantially revised 5.0-litre V8, rated at 215 kW and 411 Nm, with a six-speed ZF manual gearbox and distinctive aerodynamic bodywork. Production totalled 302 examples.

This Sydney car wears the model's Durif Red paint and shows 21,205 km, which the auction description does not warrant. Its grey leather interior is a notable detail: the seller believes it is one of only 11 cars with that option, a claim that should be checked against supporting documentation. The accompanying original logbook, purchase paperwork, certificate and VHS tape add material worth examining when assessing its history. View the featured VN SS Group A.

VN SS Group A prices in Australia

The AutoMarkets VN SS Group A market records three sales from $136,250 to $190,500, averaging $160,583.

The latest recorded example, a 1990 car with 103,891 km, sold for $136,250 on 17 March 2026. A 1991 example showing 38,916 km recorded $190,500 on 28 August 2024.

Those results establish useful historical reference points, but three different cars sold on different dates cannot isolate a mileage premium or prove a market trend. For this example, the combination of indicated distance, factory specification and supporting history gives buyers concrete factors to investigate before comparing its eventual result.

5. 1970 Porsche 911 S 2.2: a restored early air-cooled 911

The early long-wheelbase Porsche 911 S brings air-cooled character and a compact, uncluttered shape to the final spot. This 1970 2.2-litre example in Knoxfield is left-hand drive, with a five-speed manual gearbox, silver paint, Fuchs wheels and a black-and-houndstooth interior.

The seller reports a comprehensive restoration by Skunkwerks, a gearbox rebuild and fewer than 1,000 km travelled since that work. Its replacement S-specification engine, built by Michael Garner, is explicitly described as non-matching. That distinction belongs near the centre of the car's story, alongside the reported restoration quality. A copy of the original Kardex accompanies the car, while the indicated 44,873 km is not warranted. Explore the 1970 Porsche 911 S 2.2 and its photographs.

Early Porsche 911 S market context

AutoMarkets' 911 S long-wheelbase market currently records three sold examples, with results between $105,000 and $119,500. Their specifications explain why that range needs context:

• A 1971 911 S 2.2 Targa recorded $119,500 on 23 December 2021.

• A 1969 911 S with a 2.7 MFI engine recorded $115,000 on 10 March 2025.

• A 1973 911 S Targa with a 3.0 SC engine recorded $105,000 on 7 April 2025.

This is a small, mixed group of cars, including different body styles and replacement engines. It should not be treated as the current value range for a restored 1970 S coupe. The featured car's restoration invoices, engine specification and documented identity offer a more useful basis for deciding which past sales deserve the most weight.

Follow the auctions and compare the results

These five cars make a varied Australian auction watchlist: the Corvette for its LS7 and manual gearbox, the Gallardo for early V10 appeal, the Skyline for its modified Japanese-classic character, the VN for its homologation history, and the Porsche for its restoration story.
