CommSec market analyst Juliette Saly said it was encouraging to see the market gain strength towards the close of the session.
European markets were subdued on Thursday, but Wall Street gained ground after jobless claims data signalled that the US labour market was getting back on its feet, Ms Saly said.
"That's given a little bit of positive sentiment to the market and also suggests that Wall Street is going to open higher again tonight," she said. "We've certainly seen good support coming through for financial and mining stocks today."
