Australia bushfires: Aussie community heaps praise on hero Kiwi firefighters

Fire and Emergency New Zealand personnel in Australia helping to fight the bushfires have been praised by locals and welcomed with open arms.

An additional 21 firefighters left NZ and arrived in Australia on Wednesday, bringing the number of firefighters sent across the Tasman to 179 since October.

A heartwarming photo posted to Facebook by New South Wales' Bungendore Rural Fire Service shows a silver fern flag perched above one of the brigade's trucks.

"Welcome to our colleagues from Fire and Emergency NZ who are here to help on the Charleys Forest fire giving local crews a bit of respite," the post says

Australians commenting on the post were overwhelmed their Kiwi neighbours had been so willing to come over and help.

"A little country with a big heart who always punch above their weight. Thank you New Zealand," one Facebook commenter said.

Most said how proud they were of all the firefighters on the ground - Australians and Kiwis.

"Thank you so much for coming to help us," another commented on Facebook.

On Monday, vital supplies are being helicoptered into remote parts of Australia's fire-ravaged Kangaroo Island.

Blazes are continuing to burn across the area - which has already lost 200,000 hectares.

Australia's Defence Force is expanding its presence to help with the clean-up and recovery.

Visitors are being urged to stay away from the island for now, with fears warmer weather and unfavourable conditions could lead to more fire outbreaks and flare-ups.
