It was a major international brand of Chevron's until that 50% owner sold out in 2015. Caltex transitioned to Ampol branding due to Chevron terminating its licence to use the Caltex brand in Australia. Ampol has operated for more than 100 years. It owns and operates a refinery at Lytton in Brisbane, but closed Sydney's Kurnell refinery to focus on the more profitable distribution/retail segment. It successfully completed a NZD 2.0 billion bid for New Zealand peer Z Energy in first-half 2022.
