Northern Territory firefighters who flew down from Darwin to help out on the southern New South Wales coast were confronted by a whopper creature of the bush . It barged into a meal they were having in the open at night and demanded attention . A possum so big it was suggested that it was a mutation or had been on steroids . When it hopped up on a table it looked like a wombat , with big feet . Another possibility is that it wolfs down the choice oysters from the district , which the Territorians sampled in a big way .
