July 5 (Reuters) - Australian shares rose in light trade on Thursday, with financials accounting for more than half the gains, as investors shopped for bargains with little guidance from U.S. financial markets, which were closed for Independence Day.

The main financial index .AXFJ climbed 0.9 percent, recouping the previous session's losses, as investors swooped.
"I think what we have got at the moment is probably what we are likely to have for the rest of the day," said Christopher Conway, head of research and trading at Australian Stock Report.
The "Big Four" banks were all in positive territory, with Australia and New Zealand Bank ANZ.AX the biggest gainer among the four, up as much as 1.5 percent.
Telstra TLS.AX , which has had a troubled year so far, looked set to extend gains for a fourth session and was among the top gainers on the index.
"Telecom stocks are heavily weighted against Telstra, which we know has not performed well over the last couple of years, and that's what is driving gains in the telecom sector," Conway said.
The telecom sector index .AXTJ rose 1.7 percent.
Caltex Australia CTX.AX shares jumped as much as 3.4 percent after leading supermarket operator Woolworths Group WOW.AX entered a 15-year deal with Caltex to supply Woolworths' chain of petrol stations. news helped pull the energy index .AXEJ up 0.7 percent, with higher oil prices supporting the gains in other stocks.
