Australia's automotive sector can easily be considered one of the top-earning industries worldwide. Why? The country is among the world's leading producers of cars and related products. Specifically, the following are the sub-sectors that continue to generate revenue for the country:

• Car Parts and Accessories Manufacturing

To begin with, Australia is home to the best cast iron foundry producing top-quality, fabricated metal parts for vehicles. Products include gas and oil pipe couplings, iron engine covers, mount brakes, exhaust manifolds and forgings.

• Vehicle Rental

Aside from iron foundry, the country also boasts of its high-grossing vehicle rental companies. These are the go-to guys for convenient transport options, especially for those wishing to visit different attractions of the country. Bullitt Automotive Auto Rentals, for instance, is amongst the leading providers of quality vehicle brands (e.g. Hyundai, Toyota, Nissan) used for travellers and executives on business trips.

• Car Manufacturing

Australia is also home to some of the world's leading car manufacturers. They include the subsidiaries of Toyota, Mitsubishi, GM Holden Ltd. and Ford. These companies supply vehicles for private and commercial use to Aussie states as well as the neighbouring countries in the Australasian region. Car technology (e.g. hybrid cars, electric cars) is also a common production trend amongst these companies. This is a way to address the customer's demands for cost-efficient, environmentally friendly vehicles.

• Vehicle Maintenance

With the increasing number of car owners in Australia, it's likely that the vehicle maintenance sub-sector will also continue to earn more. That is because this sector takes charge of maintaining all types of vehicles, including heavy equipment, motorcycles and cars. Services commonly offered in this sector include engine overhauls, vehicle check-ups, repairs and installation of new parts and accessories.

With these top-earning sub-sectors (e.g. cast iron foundry, auto rentals, car manufacturers), its undeniable that Australia's automotive industry will continue to thrive.
