SYDNEY - Australian consumer price inflation unexpectedly picked up to a five-month high in April due in part to increases in petrol, health and holiday costs, bolstering expectations that interest rates would not be lowered any time soon, Reuters said.

Data from the Australian Bureau of Statistics on Wednesday showed its monthly consumer price index (CPI) rose at an annual pace of 3.6% in April, up from 3.5% in March and above market forecasts of 3.4%.

Moreover, a closely watched measure of core inflation, the trimmed mean, also accelerated to an annual 4.1%, from 4.0%. The CPI excluding volatile items and holiday travel stayed at an annual 4.1%.
