REPUBLIKA.CO.ID, SYDNEY -- Some 600 of the biggest firms operating in Australia, including Qantas and Glencore, paid no income tax in the 2013-14 financial year, data showed Thursday as the government vowed to keep targeting loopholes.

There has been a global push, including in Australia, for large local and multinational companies to stop using sophisticated structures to avoid or lower their tax payments, which has seen governments lose billions in revenue.

The tax details of around 1,500 large corporations were released by the Australian Taxation Office as a "step forward in improving corporate tax transparency", its Commissioner Chris Jordan said in a statement.

While Jordan said companies that did not incur a tax bill were not necessarily avoiding payments, he warned multinational firms -- some of which fronted a parliamentary inquiry this year on tax minimisation -- that their "aggressive arrangements" would be scrutinised.
