Household debt has increased at the fastest pace in nearly three years as consumer and housing loans picked up.
Reserve Bank figures show seasonally adjusted total household borrowing rose 0.3% to $188 billion in June. That's the highest level since October 2009.
The annual growth in household debt stood at 1.8%, the highest rate since Nov 2010.
Consumer lending also rose for the fourth consecutive month, while agricultural debt growth rose sharply despite declining commodity prices.

But a return to borrow and spend is being downplayed, with Infometrics saying the rise is subdued, and well-below average growth in the last decade.
