Sydney - An Australian terrier crossed 1 500 kilometres from an outback cattle station in Queensland to South Australia after hiding in the back of a passing truck, local media reported Tuesday.

Rusty had been staying with owner Laura Scudamore's in-laws on a property outside Goondiwindi while she was on holiday.

"Rusty's quite happy there but he makes a habit of sneaking off to the highway and trying to befriend people as they drive past," Scudamore told local broadcaster ABC.

The 3-year-old dog sneaked onto the back of a truck that had stopped in the area. 

The truck was in the middle of the outback when the driver realised he had a passenger, so he took Rusty home to Snowtown in South Australia.

"Thankfully Rusty had a collar on with a number for my in-laws," Scudamore said.

The in-laws were contacted and told Rusty had hit the road. 

Scudamore told the ABC that Rusty was having a "grand old time" with the truck driver's family.

His owner is now trying to find a way to get Rusty home, asking for help on social media.
