0628 GMT - Finding the Australian property market's pulse has been difficult in recent months, but there are still vital signs. The preliminary auction clearance rate across the combined capitals rose to 55.1% last week, the highest in 11 weeks, after a low of 47.4% for the week ending June 21, says property research group Cotality. Despite this improvement, clearance rates remain well below the decade average of 68%, it adds. The property market might get some more good news on Tuesday, when the Reserve Bank of Australia likely leaves interest rates unchanged.
