In its May issue of the international trade in goods and services, the Australian Bureau of Statistics reported a seasonally adjusted trade surplus of $1.65 billion, up from $1.1 billion in April.

The ABS said the rise in trade surplus was due to a $329 million, or 10%, jump in coal, coke and briquettes, a $157 million, or 3%, increase in metal ores and minerals, and a 4% rise in other manufactures.

Partly offsetting the increase was the other mineral fuels component, which fell $219 million or 10%.

Meanwhile, exports for May were $24.7 billion, up 6% from April, while imports rose 4% to $23.1 billion in May.
