The Withnalls are facing more hardship than anyone should have to, but you won't hear them complaining.
The Bradbury family of four is staying positive as they deal with three devastating diagnoses.
Father James was recently diagnosed with multiple sclerosis after a persistent leg injury left him hospitalised for months two years ago.
Four-year-old son Zac has cerebral palsy and a number of serious heart defects that have affected him since birth.
The youngest Withnall, one-year-old Ted, has been diagnosed with Limb Girdle Muscular Dystrophy. The condition, which has no cure, will likely see the boy wheelchair-bound from a young age.
The myriad of health problems means the Withnalls' current split-level home is not suitable for their future.
That's why mum Courtney's father Geoffrey Lavers set up a GoFundMe page to help them purchase a new block of land - on flat, rather than sloping, ground - and construct a disability-friendly house.
Mrs Withnall, a registered nurse, said a new purpose-built home would make a world of difference.
She said she and her husband wanted to make life as easy as possible for their boys.
"They don't know life any differently, so we don't want them to feel like they're missing something," Mrs Withnall said.
The 28-year-old is incredibly grateful to all the Macarthur residents who have already donated to the campaign - which raised more than $25,000 in the first three days - so far.
"James and I just want to say a massive thank you to everyone," she said.
"The support of the community really does make such a difference. It's actually been quite a shock to see the GoFundMe campaign doing so well - it's very humbling."
Mr Lavers had nothing but praise for the young family.
"If any family is worthy of a little more lift in helping them soar above their cards that have been dealt in this life, this one does," he said on GoFundMe.
"They have always put others before them, they have never complained and just go about doing the best they can.
"I believe with your support we could make a big difference, not just for my family who are barely treading water in life, but also in awareness for the many other people who suffer daily with congenital heart disease, muscular dystrophy and multiple sclerosis."
