In celebration of Hobart-born Mary Donaldson's accession to Queen Mary of Denmark earlier this year, the City of Hobart and the City of Copenhagen have honoured this historic moment while acknowledging a shared vision for more action on climate change.
Each city has marked the occasion by planting trees of significance in popular public places.
Queen Mary attended the planting in Copenhagen over night, while Denmark's Ambassador to Australia Ingrid Dahl-Madsen made her first visit to Tasmania to attend the Hobart ceremony.
Hobart planted a blue gum, Tasmania's floral emblem, at Long Beach in Sandy Bay, close to where Queen Mary attended school at Sandy Bay Infant and Waimea Heights Primary.
Students from these schools and Tasmanian Minister Eric Abetz, representing Premier Jeremy Rockliff, were also present at the ceremony.
In front of the Queen and the Copenhagen Lord Mayor Lars Weiss, the City of Copenhagen planted an oak, Denmark's national tree, in the city's largest park Faelledparken.
The blue gum will also grow to become another part of the City of Hobart's Our City Canopy campaign, aiming to increase the city's greenery combat climate change.
