More than 4000 people a day are applying for the "best job in the world" as the deadline for applications fast approaches.
A bored architect from Italy and a US soldier in Iraq are among 20,000 people to submit a video application for the $150,000 gig as "caretaker" of Hamilton Island.
Interest in the dream job has been so intense that technicians were forced to boost the server supporting the website promoting the position, www.islandreefjob.com.au, ahead of Sunday's international deadline. Locally, applications close at 9.59am on Monday.
The website's server capacity was increased in January after it crashed several times as hundreds of hopefuls uploaded their one-minute video applications.
Tourism Queensland said the looming deadline had caused a rush of applications.
"We are currently seeing a significant spike in applications and site traffic, and we expect that this weekend will see a strain placed on our IT resources," Tourism Minister Desley Boyle said.
"We are not sure if people have just been holding on out to size up the quality of the opposition or whether they have just caught onto this worldwide phenomenon but we are seeing a significant increase."
Back-up servers have been installed and outside IT contractors have been placed on standby for the weekend.
A majority of applications has come from the US, with Italy, Germany and Britain making up the top four.
The video application by Mario the "booooored" architect from Milan, Italy has been watched by 114,169 people on YouTube.
Ms Boyle said 850 Australians had applied so far.
Eleven finalists from around the world will be flown to Queensland for an intensive interview process. One of the finalists will be a "wild card" chosen by public vote.
The successful "caretaker" will live rent-free in a multimillion-dollar beachfront villa on Hamilton Island for six months.
They will be required to undertake a range of activities including swimming, snorkelling, bushwalking and exploring the islands of the Great Barrier Reef, all of which will be documented on a blog.
