Australian business sentiment improved sharply in June, with National Australia Bank’s monthly survey showing its Business Conditions index jumping to 9 from zero and Business Confidence rising to 5 from 2. The figures suggest firms are seeing stronger trading, profitability and employment conditions after a subdued May. Household sentiment also firmed. The Westpac-Melbourne Institute Consumer Confidence index rose 0.6% in July to 93.1, edging higher from 92.6 in June as respondents reported a better view of their personal finances. While the index remains below the neutral 100 level, the survey noted a pick-up in unemployment expectations, underscoring lingering caution about the economic outlook.
