Two British nationals, Demi McDaid, 23, and Jack Farrelly, 30, have been charged in Australia following the alleged discovery of 107 kilograms of suspected ketamine in the boot of a hired car in Sydney.

According to New South Wales Police, the seizure followed an investigation that began after neighbours reported suspicious activity at a short-term rental property in the suburb of Artarmon.

Officers searched the apartment and allegedly recovered around two kilograms of suspected drugs, digital scales, disposable gloves and resealable bags containing white crystalline residue.

Investigators later traced the couple to a hotel, where they allegedly found a much larger quantity of suspected ketamine, estimated to have a street value of approximately £5.7 million.Police also reported recovering mobile phones, more than £1,000 in cash and documents they believe to be drug ledgers.

Authorities allege the pair travelled to Australia with the sole intention of participating in the distribution of large commercial quantities of prohibited drugs, an allegation that has not been proven in court.The couple appeared before Manly Local Court on 30 June, where bail was refused.They remain in custody and are due to appear at Downing Centre Local Court on 26 August.If convicted of the offences alleged, they could face prison sentences of up to 15 years under Australian law.

The UK Foreign, Commonwealth and Development Office confirmed that it is providing consular assistance to the two British nationals while they remain detained in Australia.
