As any visitor to New Zealand from New South Wales will tell you, Aussies expect it to be colder when they visit Aotearoa.
But over the past few weeks, it's been New Zealand that's held on to the long lingering tail end of summer, and it's Australia that's being visited by Jack Frost.
Not only has this led to heaters racing out the door at homeware shops, it's also meant creatures without credit cards have had to turn to other methods to keep warm.
Koalas at the Australian Reptile Park in Somersby, NSW have turned to the age-old act of cuddling in order to keep warm as the park's temperature drops as low as five degrees.
When keepers at the Central Coast wildlife park entered the koala yard early Thursday morning, they were greeted by this adorable sight – a group of koalas snuggling together for warmth.
Usually in a news article we include one or two photos, but as an extra treat, all four photos of these cuties will be posted here.
The park's head mammals keeper Dean Reid said koalas are mostly okay in colder conditions.
"Koalas are well-equipped for the cold, with their thick, woolly fur but it's very early in the season for it to be this cold! The sudden change in temperatures had our fluffy koalas snuggling up together to stay warm on this crisp June morning," Reid said
The Australian Reptile Park is home to 35 koalas that are all part of an important breeding programme to help boost numbers for the threatened species.
Koala numbers have plummeted dramatically in the last 20 years due to habitat destruction, deforestation, fragmentation, car strikes and dog attacks.
Due to the recent devastating bushfires that ravaged Australia, the numbers are incredibly low.
In June last year, a NSW Parliamentary inquiry found that habitat loss remains as the biggest threat to the species' survival.
