A MAN has been fined $200 after shocking footage emerged of a quokka drinking what appears to be alcohol on Rottnest Island.

Footage posted on social media platform Instagram on Thursday showed a man helping the mammal drink from a cask labelled Vok Pina Colada.

Rottnest Island Police said they spoke to one man about the video.

A 32-year-old man was fined $200 for “interfering with fauna” and issued an eviction notice from the island.

Earlier, Rottnest Island rangers had used CCTV footage to locate those involved.

RSPCA WA Chief Inspector Amanda Swift said it was worrying people were not heeding the posted warnings.

“RSPCA WA is concerned that despite plenty of signs and warnings to visitors to not feed quokkas, yet again we see irresponsible people interfering with wildlife,” she said.

“Feeding them anything other than their natural diet can be extremely harmful, and alcohol can potentially kill an animal as small as this.

“What concerns us is that people do this and post it on social media thinking it’s funny, when it is actually intentional cruelty that can have severe or fatal effect on the animal.

“This is not a laughing matter. We need to put a stop to this.”

Acts of animal cruelty can attract fines of up to $50,000 and five years imprisonment.

Penalties up to $20,000 are also on the cards for those feeding fauna without lawful authority.

A number of people have been fined for their mistreatment of quokkas in previous year.

Two French tourists were fined $4,000 each in 2015 for lighting one of the mammals on fire using a deodorant can.

In the same year an 18-year-old was fined $2500 for kicking a quokka 2m in the air.

In 2016 a video posted on Snapchat showed a man pouring a vodka UDL into a quokka’s mouth.

Just last year another man was fined $4,000 after a video posted to Snapchat showed a quokka being kicked into a wall.
