The force behind Australia’s economy is its significant involvement in exporting commodities. The service sector is another contributor. (Source: US News)
These companies are listed on the Australian Securities Exchange (ASX 200). Accordingly, they serve as the benchmark for knowing Australia’s index.
These companies were selected by their market value as of April 2021.
