Barrie Tapp was a chief inspector with the RSPCA in Victoria for over 20 years before his retirement, and now works for the Animal Cruelty Hotline, auspiced by Animal Liberation.

Mr Tapp says the numbers of attacks on native animals and domestic livestock like sheep are almost unbelievable.

"You've got no idea how many complaints we get of people attacking kangaroos just for the fun of it," Mr Tapp says.

"We can't keep up in Victoria. It's never been so bad as it is for the moment. And it's getting worse. People are completely confused as to what's going on in this state at the present moment. It's unbelievable, fair dinkum. The complaints we get daily are just unbelievable. We can't keep going."

Mr Tapp says a combination of a lack of animal welfare education and a lack of regulatory oversight means people who commit cruelty are unlikely to feel remorse - or get caught.

"It's a lack of education and a lack of resources submitted to the RSPCA," he says.

"We need an independent office of animal welfare for a start -completely independent of all other agencies. There's no criticism of any agency; it's just that they haven't got the the manpower or the resources to carry on.

"If we had an independent office of animal welfare, completely run by the federal government or state government with experienced trained officers, we'd probably sort the problem out economically, with fines and jail sentences to match.

"It's distressing. It's very distressing. And I've been in the game for at least four decades. And it is getting worse. Let me tell you it is getting worse."

Anyone with complaints about acts of animal cruelty can call the Animal Cruelty Hotline on 1800 751 770.
