A Sumatran tiger from Perth Zoo has been flown to London as part of an international breeding program.
Melati, a female tiger, arrived at London Zoo on September 29 following a massive logistical operation to fly her around the globe.
The tiger flew in a special travelling crate equipped with an infrared camera so she could be monitored by a keeper from London Zoo throughout the journey.
Logistics company DHL temporarily reconfigured its global network so Melati could be delivered in less than 24 hours and space was made on board for her "luggage", including about 5kg of meat and eight litres of water.
On Sunday, Melati was joined by a male tiger from Akron Zoo Ohio in the US, Jae-Jae, who was flown to London two weeks later to allow Melati time to mark her territory.
Sumatran tigers are critically endangered and the pair will take part in a breeding program at the zoo.
