But it also has a high-performance V6 sedan in the contest, with a price tag of more than A$60,000 on the road.
The Stinger is pitched as a spiritual successor to the Holden Commodore, as it comes with rear-wheel drive and a twin-turbo 3.3-litre V6 engine.
Hyundai's finalist is its top seller, the i30, after a complete overhaul earlier this year.
Their rivals range from the Suzuki Swift baby car to the high-performance Honda Civic Type-R hot hatch and the prestige Audi Q5.
"Every year, it's getting more difficult to separate the best from the rest. Brands that buyers once turned their backs on are now every bit as good as the established players, while safety technology usually reserved for expensive luxury cars is increasingly available on cheap hatchbacks," says the motoring editor of News Corporation, Richard Blackburn.

Korea is now the third-largest supplier to Australian showrooms, beaten only by Japan and Thailand - a low-cost manufacturer mostly responsible for utes including the Ford Ranger.
Once a bit player, Kia is on track to overtake Volkswagen and Nissan this year, after overhauling established brands Subaru and Honda.
A total of 147,390 Korean-made vehicles were sold by the end of October, for a 7.6 per cent growth rate that trumps both Japan and Thailand.
If a Korean car wins, it won't be the first time they have starred.
The Hyundai i30 claimed the crown in 2007, the Kia Rio won in 2011 and the Kia Sorento SUV powered past the Mercedes-Benz GLC to take the title in 2015.
