Top 10 Largest Australian Companies by market capitalisation

The powerhouse mining and financial services industries dominate the ASX, just as they do the Australian economy. However, a couple of other household names, as well as biotech market-darling, also manage to make the grade.

What are the largest companies in Australia by market capitalisation?

Gazing upon a list of Australia’s 10 largest publicly listed companies by market capitalisation provides a succinct insight into the structure of the Australian economy. The major mining companies, who’ve for years benefitted the Chinese economic boom, and the Big-4 banks, who’ve enjoyed many of the spoils of several property booms, occupy 6 out of the 10 spots on the list, and 4 out of the top 5.

More broadly, Financial Services companies make up 28.1% of the ASX200, while Basic Materials make up 20.1%. Healthcare is the next highest concentration, making up 9.9% of the benchmark.

It’s certainly a dense concentration of value. And while it’s true that the overall fortunes of the Australian economy and ASX are leveraged significantly to the fate of the miners and banks, for investors and traders interested in entering the Australian share market, it is far from the full story. Conveying the changing face of the Australian economy, global investment bank Macquarie Group holds its weight amongst its financial services cousins, biotechnology firm CSL is a growth-investor favourite, and retail giants Woolworths and Wesfarmers are perennial investor staples. Other stocks, such as Afterpay, while not in the top ten, are catching up fast. Afterpay is currently the 14th largest publicly listed company in Australia – an impressive feat given that it was founded just seven years ago.
