Australia coach Mickey Arthur concedes injuries to his young fast bowlers are frustrating but says it is important to stay patient with them.
Star teenager Pat Cummins has been sidelined for periods through injury, while James Pattinson has also struggled to stay fit.
In stark contrast, the likes of England and South Africa have seen their speedsters enjoy a fairly good spell on the injury front.
Arthur, whose team are preparing for a one-day international against Afghanistan before taking on Pakistan in the United Arab Emirates, said the quicks needed to be given time.
"It is a little bit frustrating to be honest. Age 25 to 30 though is when the quick bowlers are at their most durable," the South African said.
"A lot of our young guys - Pat Cummins, 19, James Pattinson, 22, Mitchell Starc, 22, these are young guys who are still learning the game.
"The message is definitely be patient with the young guys. Their bodies are growing. They're certainly not anywhere near conditioned right yet. They're definitely a work in progress."
Australia captain Michael Clarke said the injuries had allowed his team to show off their depth, but added the young quicks were eager to start playing on a regular basis.
"It's positive that we've got good stock," Clarke said.
"We've got a good group of young, talented fast bowlers, but I'm pretty sure the boys would like to get some confidence in playing a lot of cricket in their bodies."
Australia will face an Australia A side in an intra-squad one-day match in Darwin, where they are using the hot conditions to prepare for the weather in the UAE.
Arthur said spin would play a big part in Australia's series against Pakistan, with the pitches in the Northern Territory set up to turn.
"We've tried to replicate it. The cricket union here has been outstanding in providing those facilities for us. Everything we've asked for has happened," he said.
"The wickets have turned. They've turned quite a lot. It's just been good preparation. I don't think we could have got this type of preparation at this time of the year anywhere in Australia.
"We're very, very happy with what we've achieved from it."
