"It's just very unfair," Jerry Wallwork told the ABC.
"A man is a man and a woman is a woman and I know a lot of changes have gone through, but in the past Laurel Hubbard used to be a male champion weightlifter," he said.

However, despite Wallwork's verbal protest, there is not going to be an official protest which stops Hubbard from competing.
The Herald understands that there have been no protests filed by any of the organisations involved at the Games, and the Secretary General of the Oceania Weightlifting Institute also said that, despite Wallwork's comments, there will be no protest coming from their camp.
"She's done everything according to the IOC rules and she's proven that she's a woman," Paul Coffa told the ABC.
"You can't stop criticism, but I see it differently, she's done what she's required to do, so give her a chance and let her continue."
Hubbard will get that chance tomorrow, with her final beginning at 4.00pm.
