Feb 6 (Reuters) - Australian shares were largely flat on Monday, with gains in mining and energy stocks keeping the benchmark index afloat ahead of a central bank policy decision, while top gold miner Newcrest Mining surged on a $16.9 billion buyout offer.

The S&P/ASX 200 index was up 0.05% at 7,561.90, as of 2349 GMT. The benchmark ended 0.6% higher on Friday.

The Reserve Bank of Australia is widely expected to deliver a fourth straight quarter-point interest rate hike on Tuesday and will likely follow up with a similar sized increase in March as it fights an unexpected revival in inflation, a Reuters poll showed.

Data on Friday showed U.S. job growth accelerated sharply last month, while the unemployment rate was at its lowest in over half a century, pointing to a stubbornly tight labour market and a potential headache for Federal Reserve officials in their fight against inflation.

Mining stocks jumped 1.3% and kept the benchmark afloat, with BHP Group, Rio Tinto, and Fortescue Metals Group adding between 0.9% and 1.4%.

Meanwhile, OZ Minerals' A$9.6 billion ($6.61 billion) buyout by BHP received approval from the Brazilian competition regulator, and is now subject to shareholder vote expected in early April.

Separately, Beach Energy reached a deal with Italy's Webuild SpA to complete delivery of the A$768 million ($531.53 million) Waitsia Stage 2 gas project.

Gold stocks jumped as much as 4.5%, with Newcrest Mining rising up to 14.4% after the company received a $16.9 billion initial takeover offer from U.S.-based Newmont Corp.

Tech stocks fell 0.3% after the Nasdaq closed lower on Friday. ASX-listed shares of Block Inc fell 0.6%, while Xero slipped 0.4%.

Financials fell 0.1%, with all the "big four" banks trading in negative territory.
