Lucy Zelic says trans athletes should NOT be allowed to compete against females as she joins JK Rowling by wading into row over Sydney women's football team

Respected football commentator Lucy Zelic has weighed into the controversy surrounding a women's soccer team that won a tournament while fielding five trans players, declaring she believes they shouldn't play against biological females.

The Flying Bats team took out the Beryl Ackroyd tournament in Sydney on March 24, winning every game they played and running out 4-0 victors in the grand final, with one trans player scoring six goals in a 10-0 romp on their way to the title.

Officials from rival clubs contacted governing body Football NSW to express their concerns, with some insisting the Flying Bats should play in the mixed competition, which includes men.

Now Zelic - who has hosted football World Cups for SBS - made her feelings on the controversy clear in a series of tweets this week.

'Looking at this through the lens of sport, I don't agree with transgender participants in women's sport,' she wrote.

'Not because I am transphobic, but because I am a big believer in protecting the integrity of the sport.

'Equally, transgender people are human beings and deserve to be given grace, understanding and a  place where they can be heard but no on is interested in hearing both sides of this discussion - only shouting and using radical language to demonise, cancel or destroy lives.

'It should be ok for me, or any woman - to respectfully raise concerns around the inclusion of transgender people in their spaces but it's not and that's alarming in itself.'

Zelic went on to slam anti-trans campaigners for using 'horrid and disgusting language' as she blamed them for creating an atmosphere in which people who respect transgender people feel they cannot express opinions like hers.

'Women are terrified to speak openly about this issue and that's not ok,' she wrote.

In a later tweet she added: 'The Sex Discrimination Act 1984 “protects people from unfair treatment on the basis of their sex, sexual orientation, gender identity, intersex status, marital or relationship status, pregnancy and breastfeeding.” 

'But what do we do when the safety and welfare of biological female footballers comes under threat and what protections do we have in place for them?'

Zelic also posted a link to an article quoting St Patrick's Football Club president Frank Parisi - whose team plays in the same competition as the Flying Bats - claiming 24 female players have quit the team in order to avoid playing the side. 

Her stance divided people who commented on the posts.

'During uncomfortable times when nobody is prepared to speak their mind, true leaders emerge. I hope people listen to your measured analysis. Great post, Lucy,' wrote one.

'Nothing like an "I'm not transphobic, but" immediately after a blatantly transphobic comment,' another hit back.

'Lucy Zelic even did the whole "Oh I'm not transphobic, I'm just concerned and asking questions!" schtick, like a little SBS coded Joe Rogan.... It's SO depressing F**k transphobia, f**k homophobia, f**k racism Lift up, don't punch down,' another tweeted.

The former SBS star's comments came shortly after Harry Potter author JK Rowling waded into the row by reposting the same story about the Flying Bats that Zelic shared.

On the Flying Bats' official website, they claim they are 'the biggest LGBTQIA+ women's and non-binary football club in the world'.

Club president Jennifer Peden told Daily Mail Australia: 'As a club, the Flying Bats FC stand strongly for inclusion, and pride ourselves on safe, respectful and fair play, the promotion of a supportive community for LGBTQIA+ players, officials and supporters, and the significant physical, social and mental health benefits that participation in sport brings, especially to marginalised members of the LGBTQIA+ community. We are a club that values our cisgender and transgender players equally.

'We strongly support the Australian Human Rights Commission’s guidelines for the inclusion of transgender and gender diverse people in sport.

'These guidelines, along with the Sex Discrimination Act, inform the gender inclusion policies of Football Australia, Football NSW, and the North West Sydney Football Association at the community, grassroots level at which we play.

'Trans women belong in the women’s competition because that is the gender with which they identify. Trans women have played with the club for at least 20 years, at levels ranging from beginner to skilled, just like our cis women players.

'Our players are graded on ability, and placed in the team that is most appropriate for their skill and experience level.'

A Football NSW spokesperson said the organisation takes 'pride in being at the forefront of developing inclusive policies for the sport in Australia and operates within the existing legal framework, including anti-discrimination legislation'.

'Football NSW continues to align with Football Australia's adoption of the Australian Human Rights Commission's Guidelines for the inclusion of transgender and gender diverse people in sport', under which, community players are permitted to participate in Football on the basis of the gender with which they identify,' the spokesperson said.

The Australian Sports Commission's statement on trans and gender diverse inclusion reads: 'All Australians should have the opportunity to be involved in sport and physical activity, regardless of their gender, sexual orientation, ability, cultural background or ethnicity.

'It is important that sporting bodies, from local clubs through to national sporting organisations, reflect the diversity in the communities they are a part of, and that together, we ensure every person is treated with respect and dignity and protected from discrimination.'
