Their families are understood to have travelled to Western Australia following the tragedy, but funeral plans for the trio are not yet known.
Late this morning, a Give a Little page was set up to help return their bodies to New Zealand.
It is not clear who set up the page, with the founder only described as "Help Bring Our Boy's (sic) Home".
"Three amazing men have been in a tragic accident and have passed away in WA ... we want to take our boy's (sic) home to New Zealand where they belong with their families, any donations will be much appreciated," the person who set up the page wrote.
Family and friends were already beginning to share the page widely this afternoon.
Mr Vergeer's fiancee, Lauren Withers, posted a link to the fundraiser on her Facebook page.
"Share this around NZ guys, people are asking to donate to NZ fund."
All three deaths have been referred to the coroner.
