Their campaign on the GoFundMe website said that the forest clean-up drive aimed to collect donations for Wildlife Victoria, which cares for sick, injured and homeless wildlife, while also showing appreciation for Poles who have already contributed to the bushfire-relief effort.
"We especially want to thank WOŚP (the Great Orchestra of Christmas Charity) which this year collected money to help Australian people and animals affected by the bushfires alongside their campaign to support healthcare in Poland," said Phil Forbes who initiated the GoFundMe drive.
"By cleaning up the Bielański forest in Warsaw, we want to show people that we ought to care for the environment where we live because it is part of the bigger, global environment, a massive part of which is burning and will continue to burn for weeks," he added.
Australians celebrate their national day on January 26.
Australian bushlands have been hit by the most severe fires in more than 100 years. At least 23 people have died and others are missing, and many people have been displaced as their homes were engulfed in the flames.
Estimates suggest that upwards of 500 million animals have been killed and that one-third of their habitats destroyed by the blazes.
