"We are recording early losses in the market today and heavier selling in the energy sector this morning following the drop in oil prices that we saw end of last week." said Adam Tout, senior analyst at CPS Capital in Perth.

Australia's core inflation rate is expected to stay below target for a sixth straight quarter through April-June, a Reuters poll predicted.
