Nov 5 (Reuters) - Australian shares firmed on Friday, clocking their best week in a month, as the country's central bank boosted its 2022 growth forecast and shares of Link Administration surged to over a two-month high on a buyout offer.

The S&P/ASX 200 index ended 0.4% higher at 7,456.90, adding 1.8% for the week. The benchmark closed up 0.5% on Thursday.

In a quarterly monetary policy report, the Reserve Bank of Australia boosted economic growth projections for next year by more than a percentage point to a heady 5.5% but remained dovish on the interest rate outlook.

Gold stocks rallied 3.6% to be the biggest percentage gainers as bullion advanced on the U.S. Federal Reserve's plan to keep interest rates steady for a while.

Top miners Northern Star Resources and Evolution Mining added 6.3% and 4.8%, respectively.

The metals and mining index added 0.7% at the end of a volatile week where iron ore prices slumped considerably. The sub-index marked its third straight weekly loss.

On the day, iron ore behemoths BHP Group and Rio Tinto advanced 0.2% and 0.6%, respectively.

Energy stocks tripped 1.6% as Woodside Petroleum lost nearly 2% on slashing its reserves estimate at a project again, while weakness in coal prices hit Whitehaven Coal .

Link Administration rose 9% to be the top gainer on the benchmark index, as the share registry firm said it would consider a fresh A$2.81 billion ($2.08 billion) offer from private equity firm Carlyle Group.

New Zealand's benchmark S&P/NZX 50 index rose 1% to finish the session at 13,074.6, with Port Of Tauranga leading gains. ($1 = 1.3530 Australian dollars) (Reporting by Anushka Trivedi in Bengaluru; Editing by Ramakrishnan M.)
