Other indicators were mixed.
A net 3 per cent of firms are expecting to lift investment, up 1 point. Profit expectations rose 3 points with just a net 10 per cent expecting profit to decline.

Firms' pricing intentions lifted 2 points with a net 50 per cent of firms also expecting

Westpac senior economist Michael Gordon said that while the post-CGT bump was expected "it was by no means the only issue that businesses have had to grumble about."
"Other Government policies such as minimum wage increases, changes to employment law, and increased regulatory requirements are adding to firms' costs," he said. "While technology changes and international competition are crimping their ability to pass on cost increases."
The persistently weak business sentiment made the prospect of another Reserve Bank rate cut highly likely, said ASB economist Mark Smith.
Smith described the post-CGT lift as barely perceptible.
"The gain was less than we had expected," he said. "[The] survey continues to paint a picture of subdued growth of investment, employment and economic activity, declining firm profitability and muted inflation pressure."
Inflation expectations fell to 1.81 per cent, the lowest since early 2017.
