Ms Bullock has been asked to explain her comment that progress on bringing the underlying inflation rate is "likely to remain slow in the September quarter".
In her response, she said that tomorrow's monthly inflation indicator is "quite volatile" but there was one thing that they were expecting to see from the data.
"We will expect to see the cost of living relief come into play," she said.
"And what that's going to do is that's going to lower energy prices. Fuel prices have also come down in recent months. So we're expecting it could well be on current forecasts, that the headline inflation rate comes in 12 months, ended below 3%.
"So that is important because it's reflecting cost of living relief. So it is reflected in the prices that people are seeing. But it's not really reflective of the underlying inflation pulse, which is more what we are observing happening with services really, which is the crux of the matter."
