A former tradie who embarked on an incredible journey to embrace her true self has offered a unique insight into her new life.

Summer Jane Day told A Current Affair she had been living full time as a woman for "maybe three years".

Her new look is a long way from when she was living unhappily as tradie Michael.

Summer said she had the facade "down pat", with not even her loved ones suspecting how unhappy she was. (9news)

"I pretty much had the facade down pat, no-one picked it," she said.

Summer's wife Atsko admitted she was shocked when the Summer first opened up to her – but their relationship as parents of two kids has stayed strong.

"It took a while to get it out but it came out, and she showed me the love and support that I was praying I'd get from her," Summer said.

Atsko said they were still "family" as well as great friends.

Now, when Summer looks in the mirror, she said, she feels "euphoric".

"No more conflict going on. Outside matches the inside," she said.

Summer's mum Anne admitted she "grieved" for the loss of her son but did not think of "Michael" anymore.

"I have a joyous daughter that I always wanted," she said.

And while Summer said she had only lost one "so-called friend" during her transition, she had left the tradie life behind.
