CANBERRA, July 14 (Xinhua) -- Australian Treasurer Jim Chalmers says he is not concerned about the accidental publication of advice that recommended the federal government raise taxes.

The confidential advice, which was prepared by the independent Treasury and provided to the governing Labor Party following the May 3 general election, was mistakenly sent to the Australian Broadcasting Corporation (ABC) and published on Monday.

It advised the government that it must find additional taxation revenue and reduce spending in order to achieve a "sustainable" federal budget.

Additionally, it said that Labor's key promise to build 1.2 million new homes over a five-year span between 2024 and 2029 will not be met and briefed Chalmers on the consequences for Australia if there is a global loss of confidence in the U.S. dollar or the independence of the U.S. Federal Reserve.

Speaking at a press conference on Monday morning, Chalmers said that the documents were sent to the ABC in error and that he is "pretty relaxed" about the leak.

He said that the government has already made it "really clear" that more needs to be done to make the economy more productive and more resilient and that tax reform will be discussed when he hosts experts, business leaders and trade unions in Canberra for a landmark three-day economic summit.

Chalmers conceded that the government will fall short of its housing target on the current trajectory but said that the target can still be met.

A report published by the National Housing Supply and Affordability Council in May forecast that 938,000 dwellings would be built over the five-year period. ■
