Australia Post is supporting Earth Hour this year with a commemorative set of three stamps, each featuring an animal and the messages "Lights Out", "Switch Off" and "Save Energy".
The artwork on the Australia Post stamps is driven by the concept of protection, with the presence of wildlife in the designs emphasising the need to protect the planet and all life it sustains by reducing harmful greenhouse gas emissions.
"Australia Post is a committed supporter of this important environmental initiative," said Noel Leahy, Group Manager of Philatelic, Australia Post.
"The health of the environment is an important global issue and through this stamp issue we hope to engage the community in efforts to help combat global warming by reminding and encouraging them to turn off their lights at 8.30 pm on Saturday 28 March."
The striking designs of an owl, possum and orangutan represented in the three stamps are designed to appeal to all Australians and particularly young people.
Other collectable products in this issue include a first day cover, stamp pack, postmark, booklet of 20 x 55c stamps, stamp and medallion cover, prestige cover and maxicard Set. The issue is available at selected Australia Post outlets, via mail order on 1800 331 794 or online at Auspost.com.au from 11 March 2009 until stocks last.
