Four years ago Anastasia Rea committed to aim for the Queen's Guide Award, the highest award in Girl Guides.

The accolade requires community service, organisation skills, and a long-term commitment to guides with up to four hours a week work.

The 17-year-old, a guide since age nine, also did a certificate two in agriculture and coached netball, which contributed to the award.

Girl Guides leader Linda Holmes awarded Anastasia two metal and three fabric badges on Wednesday among a small group of fellow Guides and family.

"It is so surreal," Anastasia said. "I'm not only finishing my Queen's Guide, but I'm also finishing Guides as well and that's sort of a chapter of my life over. I think without Guides I'd be a completely different person."

She will go to Melbourne's Government House in February to receive a certificate signed by the Queen.

"Usually around 10 to 15 people Australia-wide get it. It's a very hard award to get, it takes a lot of time and effort, and a lot of people don't continue Guides long enough to complete it as well," Anastasia said.

Ms Holmes said the Warrnambool Girl Guides had grown this year, but the group was looking for teenagers to continue on or join.

"We need girls 13 to 17 year old, they all sort of drop off when they head off to high school, whereas Anastasia, and there's been a couple of others, have persisted through and set themselves up for the future," she said.

She said Girl Guides helped with leadership, teamwork, personal development and community service.
