Australian shares extended gains on Wednesday after Tabcorp Holdings (TAH) said it agreed to takeover Tatts Group (TTS) in a cash-and-stock deal, helping the target company post its biggest-ever intraday percentage gain.

The S&P/ASX 200 index (xjo) rose 0.4 percent or 20.05 points to 5,430.8 by 0057 GMT.

The A$6.36 billion ($4.87 billion) takeover of Tatts will create a A$10.44 billion betting industry giant that could help fend off popular online rivals.

"The Tatts-Tabcorp deal is certainly a positive because it is a takeover corporate action and it has helped the markets," said Will Keenan, general manager of direct equities research at Lonsec.

Tatts jumped as much as 18.1 percent to a 9-month high, with 12 million shares trading, about 2.5 times its 30-day average volume. Tabcorp climbed as much as 2.9 percent.

"Another positive is that the bond yields have retreated a touch overnight and they had been creeping up," Keenan added.
