They are the two most iconic Australian animals.

And it seems this kangaroo and koala were getting into the spirit of Australia Day as they wished each other a heartwarming 'G'day'.

Zookeepers at Symbio Wildlife Park introduced a koala joey to a group of playful kangaroos - and they looked like they were getting on like a house on fire.

Cute: Nuzzling in, the inquisitive kangaroo sniffed at the young koala as the ranger cradled it in her arms

While some of the wallabies and kangaroos were more interested in nibbling on some grass, one curious roo decided to take a closer look at his fellow marsupial.

Nuzzling in, the inquisitive kangaroo sniffed at the young koala as the ranger cradled it in her arms.

The koala happily reciprocated and appeared to be enjoying the attention.

After a few minutes of playing with the koala, the kangaroo hopped off to join the rest of its friends.

The wildlife park, in Helensburgh, New South Wales, posted the video as it wished its supporters a happy Australia Day.

They captioned the video: 'Just a koala joey and a kangaroo saying maaaaate! Happy Australia Day.'
