Five girls from Tamworth and Armidale will head to Sydney this month for national talks on climate change and activism.
The 12- and 14-year-olds will attend the School Strike 4 Climate Summit on January 20, and have even taken on leadership roles for the sold-out event.
Davina said such an event was valuable because it was "important to learn from other people and to help grow our movement".
Lucy said she wanted the group to "build relationships and connections ... with other strikers all across the country".
The agenda for the event has not yet been released, but Lucy said she believed the speakers would include "lots of influential people".
She will emcee for part of the summit with a Cairns peer; Lucy and Chiara will also be home group leaders.
Organisers said the event's aims included reflecting on achievements and "shaping big bold plans for the coming year to move forward with hope, power and courage".
