Australian shares ended the week on a positive note, boosted by heavyweight banks, as investors cheered the government's signals to ease lending standards to free up credit and revive the pandemic-hit economy.

The "Big Four" banks helped the S&P/ASX 200 index close 1.5pc higher.

The benchmark index recorded its best weekly gain since the week ended Aug. 14.

The changes remove responsible lending laws introduced in the wake of the global financial crisis that, among other things, require banks to check whether information provided by borrowers in their loan applications is correct.

Calling the move a very good sign from banks' point of view, Henry Jennings, senior analyst and portfolio manager at Marcustoday Financial Newsletter said, "It would enable people to get a loan quicker, speed up the paperwork, free up the credit market and hopefully stimulate some economic activity."

Jumping nearly 7pc, Westpac Banking Corp was the biggest percentage gainer among its peers with others adding between 2.8pc and 6.4pc.

Aiding sentiment, Fitch Ratings said the A$1.3 billion ($918.19 million) record fine agreed by Westpac to settle a lawsuit by financial crime agency AUSTRAC is manageable for the Australia's second-largest lender.

Among other gainers, gold stocks rallied more than 2.5pc as bullion prices recovered from a two-month low.

Shares of the top listed gold miner Newcrest Mining advanced 2.6pc while Northern Star Resources snapped a six-day losing streak.

Across the Tasman Sea, New Zealand's benchmark S&P/NZX 50 index gained 0.9pc to end the session at 11,797.08.

Local shares of Westpac Banking Corp climbed 7.7pc, while Australia and New Zealand Banking Corp marked its best day in more than three months.
