May 17 (Reuters) - Weak bank stocks pushed Australian shares down on Wednesday while poor wage growth data and a dip in consumer confidence dampened sentiment.

Westpac Banking Corp was set to trade ex-dividend on Thursday.
As banks are starting to go ex-dividend, investors are holding on to receive dividends. There are concerns that once dividends are paid there will be pressure in the sector as investors diversify holdings, said Michael McCarthy, chief market strategist at CMC Markets.
"It could be selling ahead of the ex-dividend dates of ANZ and Westpac."
