Four Pacific women have been given Queen's Young Leader awards for their work dealing with social issues in their countries.

The awards, now in their third year, celebrate exceptional people aged 18 to 29 from across the Commonwealth.

Climate change in Carteret Islands in Papua New Guinea is the focus for award recipient Johnetta Lili who is working with people losing their land to rising waters.

Papua New Guinea's Theresa Gizoria got an award for helping young mothers in tertiary education.

Another Pacific woman acknowledged for her community work was Solomon Islander Karrie Jionisi, who helps unemployed girls and single mothers to learn new skills to help them find jobs.

She said gender equality in Solomon Islands was an ongoing issue, which is what motivated her to start up a programme called Girls for Change.

In Tonga, Elizabeth Kite received an honorary award for her work with youth and disabled people.

The four women all spent one-week in the UK for a residential programme, as part of the award.
