But Commsec economist Savanth Sebastian said Western Australia's economy was holding up better than the state final demand figures suggested because iron ore was still being exported at record rates, despite the lower prices.

He said if net exports were included Western Australia's economy had grown by 1.3 per cent in the March quarter, while Queensland had slipped by 0.1 per cent. (Victoria's economy was up 3.3 per cent, while NSW was up 1 per cent, with exports included).

"You need to factor in the exports because exports are such a large part of WA's economy. When you look at it from that perspective it provides a different view," Mr Sebastian said.

"There is still a lot of housing and infrastructure growth in WA which is holding up the result a lot better than we expected."

Western Australia Premier Colin Barnett has come under pressure as the economy of the once booming mining state slows, forcing him to reverse his position on asset sales. Western Australia's economic growth rate has fallen to 2 per cent in 2015-16, the lowest rate since 1990-91.

But Mr Sebastian said Queensland's economy was still struggling and was in worse shape than Western Australia.

"If you had to describe WA's result you'd call it patchy, but Queensland you would describe as concerning," he said.

"Queensland is finding it very difficult at the moment, especially as population growth is about the weakest it's been in 15 years. It's not due for a significant turnaround in the near term," he said.

Queensland Treasurer Curtis Pitt last month revealed the state had fallen into recession in the second half of last year.

He said the state final demand figures showed the state's economy was "turning the corner".

"This figure represents a quarterly rise in household consumption, dwelling investment and public final demand. This is good news for Queensland," Mr Pitt said.
