Australians will be reeling at Wednesday's gross domestic product numbers that put their country as one of the world's slowest growing developed economies, behind even financially beleaguered Greece.

Australia's GDP growth from April until June came in lower than expectations at 0.2 per cent, the economy's weakest quarter of growth in two years.

The underwhelming data has Australia growing faster than Brazil, Japan and Canada, all of which are experienced negative economic growth, but more slowly than Greece, Poland, South Korea and most other developed nations.

"For some time we have been forecasting a marked easing in GDP growth in response to the collapse in commodity prices and the end of the mining boom. This now appears to be underway," senior Asia economist at Capital Economics Daniel Martin said.
