Australia will play Scotland on Tuesday June 5, and then just four days later will back up for the first of three tests against Wales in Brisbane.
To make the strain on players even tougher, NSW, Melbourne and Brumbies stars will be forced to back up from round 15 of Super Rugby on the weekend for the Test against Scotland in Newcastle.
Robbie Deans unveiled his new-look Wallabies coaching assistants on Monday, with Tony McGahan appointed as coaching coordinator, Andrew Blades as forwards coach and Nick Scrivener as coaching assistant.
Scrivener, who has experience coaching in Scotland, said the two Six Nations teams will sense the Wallabies are vulnerable and be ready to strike.
"They'll be looking to ambush us," said Scrivener.
"They beat the Wallabies last time a couple of years ago at Murrayfield. They'll know what our lead-in will be, they know our circumstance and they'll definitely smell some blood and go at us really, really hard.
"We wouldn't expect anything less."
However, despite the unprecedented nature of the scheduling, Australia say there are no excuses.
Queenslander McGahan will return to Australia shortly before the tests to look after defence and assist Deans in the overseeing of the side once his Irish side Munster finish their season in late May.
Former Wallabies prop Blades will look after the set-piece and he returns to the Australian coaching set-up for the first time since 2004.
The Wallabies scrum is often criticised, but Blades said it wasn't unrealistic for Australia to aspire to having the best pack in world rugby.
"I can't wait to get to know the group and set out a plan with them to help them achieve what they want which is probably to become the best in their position in the world," Blades said.
"There's been some really good individual performances in Super Rugby so far in terms of the set-piece, and some of the young guys are really developing just by being involved in the Wallabies program over the last couple of years.
"Cohesion will be (the biggest challenge) initially - getting the group understanding each other and working together.
"It'll be getting that mentality across the group that we're ranked No.2 in the world, so we've got to aim up and try and make the next step."
