Scotland's history-making referee will make her debut in The Rugby Championship next week.
Last month, she became the first female official to referee world champions South Africa during their clash with Portugal.
Now she will be involved with the Springboks again as an assistant referee for their Rugby Championship opener against Australia in Brisbane on August 10.
Davidson and New Zealander Paul Williams will assist English referee Luke Pearce for the match at Suncorp Stadium.
That is one of two appointments for the 31-year-old Scot during The Rugby Championship, which sees New Zealand, South Africa, Australia and Argentina compete for the title.
She will also be an assistant referee when the Wallabies host the Springboks in Perth on August 17.
On that occasion, Williams will be the man in the middle, swapping with Pearce who assumes assistant duties alongside Davidson.
It is the latest milestone in the career of the former Murrayfield Wanderers player, who suffered a serious shoulder injury just as she was set to earn her first Scotland cap as a player. It eventually forced her to hang up her boots and turn to refereeing.
Earlier this year, she became the first Scottish female referee to be part of the officiating team in a Guinness Six Nations match.
Davidson is one of four assistant referees who will debut during The Rugby Championship alongside Wales' Craig Evans, Gianluca Gnecchi of Italy and Damián Schneider from Argentina.
Schneider took charge of Scotland's summer tour finale against Uruguay.
Joel Jutge, World Rugby's high performance 15s match official manager, said: "In this new, four-year cycle we have the opportunity to expand our group of match officials, as demonstrated in July.
"This is with the long-term goal of arricing at Rugby World Cup 2027 and beyond to 2031 with a deeper talent pool.
"For The Rugby Championship, we have mirrored the Six Nations in terms of selection.
"Some will be experiencing the Six Nations and The Rugby Championship for the first time, and that is important to our overall goals.
"Our on-field approach has been shaped by teams and match officials in tandem, meaning that there is a good understanding of the ‘critical few’ focus areas.
"As we drive forward and enable the newer members of the team to gain experience, all should remember that we are implementing a longer-term strategy within a reshaped international calendar from 2026.”
