The England and Wales Cricket Board (ECB) will hold talks with Cricket Australia over coronavirus restrictions during the Ashes amid concerns that several senior players may be reluctant to tour.
Joe Root's side are due to start their bid to regain the urn at The Gabba on December 8, with the fifth and final Test scheduled to begin at Optus Stadium in Perth on January 18.
Multi-format players such as Ben Stokes and Jos Buttler would face several months away from home, with the T20 World Cup taking place in the United Arab Emirates prior to the Ashes.
It is unclear whether COVID-19 rules may prevent families from travelling to Australia and England players have been in talks this week to seek clarity over restrictions that may be in place.
The ECB and the Professional Cricketers' Association (PCA) say player and staff welfare will be a priority as they prepare to hold discussions with Cricket Australia.
A joint ECB and PCA statement said: "This week, several meetings have been held between the England men's players, ECB and Team England Player Partnership to discuss provisional plans for the tour of Australia later in the year.
"All parties are collaborating and will continue to work together to understand protocols around bubble environments, family provision and quarantine rules that will be in place for the tour during the current COVID-19 pandemic.
"With player and management’s welfare paramount, the ECB will discuss planning and operational requirements with Cricket Australia in the coming weeks and how they seek to implement their policies in partnership with state and federal governments.
"All stakeholders are committed to putting player and staff welfare as the main priority and finding the right solutions that enables the England team to compete with the best players and at the highest possible standard that the Ashes series deserves."
