Australian shares see-sawed between gains and losses on Monday, with a jump in energy stocks currently lifting the benchmark index, while heavyweight miners and gold companies fell ahead of a production-reporting week from top miners and energy firms.

The S&P/ASX 200 index was up about 0.12% at 7,402.6 points by 2334 GMT, after slipping 1% on Friday.

The energy sub-index led gains as oil prices remained robust on tight supply and worries of a Russian attack on neighbouring Ukraine.

However, the mining sub-index weighed on markets, falling 0.2% on weak iron ore prices.

Fortescue Metals slid 1.4%, the most among Australia's big miners. Rio Tinto fell 0.8%, while BHP Group was largely flat.

Investors now await quarterly production numbers from miners like Rio Tinto, BHP Group and oil majors like Woodside Petroleum during the week.

Separately, BHP said on Monday it would buy battery electric trains to deliver iron ore from its mines to ports in Western Australia, joining Rio Tinto and Fortescue that made similar purchases last week.

Gold stocks fell 0.8%, pressured by lower gold prices. Evolution Mining was down about 1.5%, while the sector heavyweight Newcrest Mining dropped 0.4%.

Among other individual shares, Australian retail conglomerate Wesfarmers rose as much as 1.8% even after it warned of a lower first-half net profit after tax due to coronavirus-induced restrictions.

New Zealand's benchmark S&P/NZX 50 index fell marginally by 0.05% to 12,783.53 points, deepening its losses from Friday.
