Sept 4 (Reuters) -Australian shares slid on Wednesday in a broad-based sell off, as lacklustre data from the U.S. dampened market sentiment globally, while local investors awaited the country's gross domestic product (GDP) data.

The S&P/ASX 200 index .AXJO fell 1.4% to 7,989, as of 1225 GMT, eyeing its worst day since Aug. 5.

Market mood soured after data from the Institute for Supply Management revealed that although slightly improving in August from an eight-month low in July, U.S. manufacturing remained muted, spurring concerns about the U.S. economy.

While in Australia, investors await the country's second-quarter GDP report to better gauge the monetary policy stance of the local central bank, which is anticipated to demonstrate an annual growth rate of 1%, as per LSEG data.

Any read in negative territory for the GDP could have a chilling effect on sentiment, and the share market, said Michael McCarthy, chief commercial officer at data brokerage platform Moomoo.
