He slipped into a coma after suffering multiple skull fractures and traumatic damage to his brain.
Gibbs was then flown home from Bali’s International Medical Center following emergency surgery while still in a life-threatening condition.
Mother Rosslyn Gibbs was shocked to learn the $200,000 process was not covered by her son’s travel insurance, prompting a warning to always read the fine print.
“They tell you [to] get insurance, get insurance, so you do and you expect that insurance to actually cover you and it doesn’t,” she told 9News.
“I had to sign that I would be responsible for the bills if they said no.”
Gibbs’ travel insurance required an additional $7 plan to cover scooter or motorbike coverage, which was detailed in the fine print – meaning coverage for any accidents involving a scooter or motorbike was not included.
The family is hoping that their crowdfunding campaign will help them pay the $370,000 medical bill.
Gibbs remains in intensive care at Adelaide Royal Hospital and is expected to start rehabilitation once he is well.
His recovery is expected to take several months.
