A paralympian has been accused of exaggerating her physical and mental impairments by her former swim coach.

Amanda Reid, formally known as Amanda Fowler, has represented Australia in swimming at the 2012 London Paralympics and won a silver medal in cycling for Australia at the Rio Games in 2016.

Now, the 21-year-old has been called out by her former swimming coach Simon Watkins and other athletes who claim she is falsifying the extent of her disability.

In an investigation from BBC's File on 4 program, Mr Watkins and fellow athletes have said they are suspicious about the young athlete's changing conditions.

In 2012, her mother Kate Reid allegedly told Mr Watkins her daughter may have a rare generic disorder with similar symptoms to cerebral palsy.

Mrs Reid allegedly asked her London coach whether her category should be changed from an intellectual to a physical impairment.

Mr Watkins claimed he then told her mother 'she [Reid] doesn't have a physical disability. So there isn't a way that you get a classification for physical disability. There isn't one present.'

Another athlete, who requested not to be named described the silver-medalist as 'boisterous'.

'There was absolutely no sign of any sort of physical impairment. She was quite boisterous and used her arms quite a bit for emphasis when she was talking,' she said.

Mrs Reid is now training and competing as a visually impaired athlete. Since the allegations, the Paralympic Committee has stood by the Australian athlete and said they followed official process

Mr Watkins stopped coaching the Mrs Reid in 2014 and claims he was shocked to see her training and competing as a visually impaired athlete.

'This is a girl who had been driving a car. So now to be with a white stick... was quite unbelievable,' he said.

A fellow swimmer has also claimed she would maintain eye contact and used her white stick as if it was a prop.

They said she 'would suddenly almost put on an act as if she couldn't see you and wouldn't be able to meet your eyes directly.'

Since the allegations, the Paralympic Committee has stood by the Australian athlete and said they followed official process.

'The APC has faith in the classification process and is fully satisfied that all requirements have been followed and met relating to Amanda's international classification under the IPC Classification code and the classification rules of the UCI,' a spokesman said to Fairfax.

According to her mother, the family have been advised to not make any comments about the allegations.

'Quite frankly this is taking its toll on Amanda's health,' Mrs Reid said.
