ASX flat

Australia's S&P ASX 200 finished near the flatline, with the country's big four lenders offering some support after the central bank voiced confidence in tighter home loan standards.

"All four major banks are enjoying good operating conditions... with a modest recovery in credit growth and business credit growth is improving, albeit modestly from low levels.
