Aug 21 (Reuters) - Australian shares gained on Friday after Wall Street's spectacular rise overnight sparked similar reaction domestically, while investors also cheered a dip in new coronavirus cases in the country's second-most populous state.

The S&P/ASX 200 index added 0.5% by 0033 GMT. The benchmark fell 0.8% in the previous session.

All the three major indices on Wall Street ended in the positive territory overnight with the tech-savvy Nasdaq finishing at a record high.

Buy-now-pay-later firm Afterpay extended gains into the second session after it nearly doubled its annual core earnings forecast on Wednesday.

Further fuelling optimism, the second-most populous state of Victoria, which has become the country's COVID-19 hot spot, reported its lowest daily rise in new cases in more than five weeks.

As of 0043 GMT, New Zealand's benchmark S&P/NZX 50 index rebounded 1.3%, wiping all the losses from the previous session after a senior official said, central bank is watching the country's labour market "very closely" to decide if negative interest rates will be needed to further support the economy.

The index set for its best week since the week ended July 3.
