The S&P/ASX 200 opened largely unchanged around 9,170 in Friday morning trade, halting its two-session record run, as losses in miners and energy firms weighed. Mining giants BHP Group and Rio Tinto led the declines, down 0.6% and 1%, respectively, while energy stocks edged lower as oil prices steadied amid caution over extended US-Iran nuclear talks. Oil and gas producers Woodside Energy fell 0.7%, while its peer Santos dropped 0.8%. Rate-sensitive sectors, such as banks and real estate stocks, also remained under pressure as tightening policy risks mounted. In contrast, gold miners supported the market, up nearly 3% to a one-month high, with Northern Star and Evolution Mining climbing 2.5% each, while Newmont added 1.7%. Technology stocks were mostly higher despite a pullback from Wall Street peers. Meanwhile, an Australian trade union has requested urgent talks with WiseTech Global after the company announced plans to cut about 2,000 jobs under a two-year AI-driven restructuring.
