Speaking with Daily Mail Australia last month at the premiere of Stan documentary Revealed – Danielle Laidley: Two Tribes, she said: ‘I think it’s an amazing way to monetise a platform.’

‘It’s really changed my life, being able to empower me and give me my own financial stability.’

The daughter of Home and Away star Mat Stevenson was spotted at the blue carpet event for the highly-anticipated doco.

She was all smiles as she posed up a storm with the star of the evening, AFL legend Dani Laidley, who was there to tell her story as a trans woman in the sports industry.

Grace commended the former North Melbourne coach for all her work introducing trans identities into AFL since her brutal outing in 2020 by Victoria Police.

‘I think her story is incredible because it’s reaching out to a demographic which hasn’t been influenced by trans identities for very long,’ Grace said.

She continued: ‘Coming from an AFL background, I think that it’s very important because she’s breaking ceilings into buildings that haven’t really been entered by trans women before. So I think that that’s amazing.’

Grace Hyland reveals what she thinks of men who date trans women

Grace has been documenting her male-to-female transition on social media since she began identifying as a girl at the age of 12.

Her father Mat Stevenson, who became a household name when he starred as Adam Cameron on Home and Away, has also been supportive of his daughter.

He discussed Grace’s transition on The Sunday Project in January 2021, and revealed how his friends reacted to learning of his child’s gender identity.

He said that while some of his friends were ‘pretty seamless’ and ‘got it’, others struggled and he asked them to simply ‘show some empathy’.

Grace said she knew she was meant to be female as early as the age of ‘four or five’, and began transitioning at the age of 12.

She consulted doctors, psychologists and experts in the field for a year before commencing any physical treatment.
