Six people including four British men have been arrested in Australia and New Zealand in one of the region's largest‑ever drug seizures.
Australian police said the bust was connected to a UK‑based organised crime syndicate which supplied highly pure methamphetamine and MDMA powder.
Drugs with an estimated value of AUD $90m were seized in the state of Queensland.
Police say the drugs could have made up to 12 million ecstasy capsules.
Queensland Police said it was the third‑largest MDMA bust in Australia's history and the drugs were the "highest purity" ever seized in the state.
Police arrested two British men, an Australian man, and an Australian woman.
Another two British men, aged 49 and 60, were arrested in Auckland, New Zealand last week after police there seized 200kg of methamphetamine.
Raids were also carried out in the Australian state of New South Wales.
