Equities in Australia and New Zealand closed at all-time highs on Wednesday, with the Australian benchmark S&P/ASX 200 index adding 0.9% to finish at a record 9,227.80 points.
The rally was broad-based, led by gains in the mining and technology sectors, which benefited from a resurgence in artificial intelligence equities and a rebound in commodity prices.
The move in Sydney followed a similar milestone in Wellington, where the New Zealand sharemarket reached a new all-time high on Tuesday.
The S&P/NZX 50 index closed at a record 13,850.69, rising 0.57% in the session.
The sustained decline in global oil prices has supported the regional rally, reducing input costs and boosting sentiment across both markets.
The simultaneous record closes highlight the growing correlation between the two markets, driven by shared exposure to global commodity cycles and technology trends.
