Australia's east coast is shivering through a cold snap this weekend, with cooler temperatures set to remain in some cities into next week.

The cool weather has stretched from Queensland to Canberra, and also hit parts of the Northern Territory and Tasmania.

Brisbane woke up to its coolest morning of the year so far at a frosty 5 degrees Celsius, while in Canberra temperatures got as low as -4.8 degrees Celsius overnight.

Here are just some of the photos from our ABC Weather Obsessed Facebook group to show how cold it has been.
