Edinburgh have signed former Waratahs duo Ollie Atkins and Grayson Hart.
Second row Atkins, 24, and 25-year-old scrum-half Hart both qualify to play for Scotland.
"The opportunity to play against some of the top teams in Europe will be a fantastic challenge," said Atkins on the Edinburgh website.
And Hart added: "It's great to be here and I'm really looking forward to representing the capital. It'll be a huge honour."
Atkins, whose father is from Scotland, played for Force before joining Waratahs while Hart, who has a Scottish grandmother, joined the Australian side from New Zealand's Blues.
The two signings, which Edinburgh say are subject to medical examination, are the first since
Alan Solomons was confirmed as the Pro12 side's new head coach.
