In a remote Papua New Guinea village with no reliable water, electricity, phone reception or medical facilities, stands a brand new school building made possible in part by a Brisbane teenager's generosity.

Jordanna Muddle, 14, used her 13th birthday party in 2018 to raise $2000 by asking guests to donate to her GoFundMe campaign instead of giving presents. The money bought a crucial chainsaw.

The PNG school building takes shape thanks to the work of the donated chainsaw.

The school building opened on January 4 and Jordanna and her family travelled to Utukwaf village in PNG, where they saw just how lacking the village was in basic infrastructure.

The Muddle family plan to return to Utukwaf with more funds and at the top of their list is establishing a reliable water supply by diverting some water from a nearby stream to the village.
