Australian shares opened higher on Monday, mirroring positive Wall Street performance and boosted by rising oil prices. Financials, consumer discretionary, and energy stocks led the gains. This rise follows a mixed performance for the benchmark index last week. Financials advanced after a previous week's decline, while energy stocks benefited from supply disruption concerns. Consumer discretionary stocks saw their largest gain in over four months. Miners experienced a slight dip, influenced by falling iron ore prices and competitor activity.
