THE Port came home with triple treat at this year's Tidy Towns Awards taking out two gongs and high commendation award.

Grahamstown Public School was named winner of the Schools Environment Award for the third year running, while the Mambo Wanda Wetlands at Salamander Bay also took out first place in the Heritage Branch Cultural Award section.

The Tilligerry Peninsula was highly commended in a water conservation category.

Assistant principal at Grahamstown Public School Leanne Russell said she was thrilled the school had again been honoured.

"This is a student-centred initiative and already the students are talking about what they can do for next year," she said.

"In the past 12 months we have planted gardens that addressed erosion issues, planted a hedge along out drive-way to reduce our carbon footprint, re-vamped our worm farm and painted murals in the toilets."

She said staff also ensured students studied environmental issues in each class.

Mambo Wanda Wetlands was recognised for its Aboriginal artist impressions of native species that were important to the local Maaiangai people and the ongoing work to create awareness of the area's significance.

The Tilligerry Creek Management Plan was recognised for its work on water quality after the introduction of the oyster farming ban.
