The strictness and length of any quarantine period as well as whether families will be allowed to travel are central to the negotiations.
Furthermore, the ECB, who chairman Ian Watmore stood down this week, have been trying to establish whether they would be exempt from any changes in rules during the tour.
And while it appears clear several details still need to be ironed out, the latest chapter in cricket's greatest international rivalry looks set to be written.
"Over recent weeks we have made excellent progress in moving forward on the England Men's Ashes Tour," a statement read.
"To facilitate further progress and allow a squad to be selected, The ECB Board has met today and given its approval for the tour to go ahead. This decision is subject to several critical conditions being met before we travel.
"We look forward to the ongoing assistance from Cricket Australia in resolving these matters in the coming days."
