Australia's trade surplus has decreased slightly to a seasonally adjusted A$1.925 billion in November from a revised surplus of A$2.561 billion in October, the Australian Bureau of Statistics (ABS) said Thursday.

The data from the ABS shows that exports of goods and services were virtually unchanged, while imports jumped 3 per cent in the period.

Capital goods for business use accounted for the biggest increase in imports, rising $314 million or 8 per cent. Consumption goods coming into the country also increased by A$52 million or 1 per cent.

Non-monetary gold mining exports posted the biggest fall, down 21 per cent. This was somewhat offset by a 1 per cent increase in rural products.

The November surplus was smaller than the median market forecast of A$2.10 billion. Economists' forecasts were in a range between A$1.5 billion and A$3.2 billion.

Experts say Australia's trade surplus could narrow further as floods, which continue to hit Queensland, hampers the country's ability to export coal.
