Mahesh Patrick, 14, and Shaun Emitja, 21, were found separately near Alice Springs on Friday and Saturday.

Both were dehydrated and suffering from exhaustion but were otherwise fine, police said.

Their vehicle had become bogged last Monday while on a four-hour drive through a remote area.

Unable to pull the car out, they stayed with the vehicle overnight before leaving the next morning to search for water.

They walked 5km (3.1 miles) to a hill before realising they were going the wrong way, authorities said.

Authorities said the shipment, which weighed 450kg, included 1,290 packages of heroin with unique red branding.

The seizure was made at the Port of Melbourne - Australia's largest port - on September 29.

Offices said they arrested a Malaysian man after the huge haul was discovered in a container of ceramic tiles.

He was later charged with the import and attempted possession of a commercial quantity of a border-controlled drug. He could face a sentence of up to life in prison.

Testing of the substance in the packages showed it was heroin.

They said it was the largest methylamphetamine seizure in Australia's history and was a joint operation between Australian Federal Police (AFP) and Victoria Police.

Federal Justice Minister Michael Keenan's office said the drugs were sandwiched between a shipment of wooden floorboards.

Two men have been charged with drug trafficking offences.

Prime Minister Malcolm Turnbull praised police and security services for the intercept.

The 903kg (1990lb) haul of the drug, also called ice, is estimated to have a street value of A$898m (£546m; $680m), Justice Minister Michael Keenan said.

The drugs were concealed between floorboards in a shipment sent to Melbourne, according to the Australian Federal Police (AFP).

Two men have been charged with drug trafficking offences.

Prime Minister Malcolm Turnbull praised the police operation, describing drug traffickers as "merchants of death".

The December 25 bust, along with a seizure of 1336 pounds (606 kilograms) of cocaine from the same syndicate earlier this year, was worth about $259 million (AUD$360 million) and is Australia's largest ever haul from a single cartel.

Police said it was among their ten largest seizures ever.

The investigation, codenamed Operation Okesi, was a joint effort between Australian Federal Police, New South Wales Police and Australia's Border Force.
