"So disappointed @AdelaideTBirds," one fan posted on Twitter. "She's been very outspoken about her issues with anyone who isn't heterosexual and therefore I can't support the team. Is it worth a win to spread ignorance and hatred?"
Several fans posted similar comments slamming the Thunderbirds and Folau.
"It would be really great if you could be transparent about the steps you've taken to ensure your LGBTIQ players and fans feel both safe and comfortable with this decision. As well as the training Folau will be undergoing in light of her comments," another fan said.
"There should be no room for homophobia in SSN," said another.
Folau, who played nine seasons with the Mystics, was granted an exemption from Netball New Zealand to play in the Super Netball competition while still being available for Silver Ferns selection.
