An Impressions version of the Koalas in Danger set of PMCs
Impressions

In August 2024, Australia Post released a set of stamps, maxicards, first day cover and three Postal Medallion Covers on the theme “Koalas in Danger”. As well as featuring the beautiful creatures, the pieces also raised money for Australia Post’s support of WWF-Australia in protecting Koala habitat.
In November 2024, Australia Post released their “Impressions” range: “Impressions 2024 are exclusive releases, with special prints and variations for your collection. Limited stock available“. As part of Impressions 2024, Australia Post released a limited edition medallion cover for Koalas in Danger. A single cover with three medallions on it, this release featured:
- Limited edition of 150 only
- Features three antique gold cut-out medallions made of zinc alloy measuring 48mm
- Cover size 230mm (w) x 162mm (h)
- Cover features foiled postmark and numbering 001/150-150/150
- Presented in a clear cover
The issue was released on 13 November 2024. They are available until sold out or until 31 December 2025.
Medallion covers

Medallion covers are a great way for Australia Post to market a cover to collectors of medallions on one of their stamp themes for which a corresponding coin is not available from either the Royal Australian Mint or the Perth Mint. Medallion covers are often not as widely collected as PNCs with coins, and I think that is a shame. Medallions often offer a larger surface to convey the subject on, often in colour, with extra relief and or interesting shapes. In this case, there are two holes between the Koala and the gum leaves.

I liked the original silver-coloured medallions, but I think the gold of this version works even better.
Stamps

Like the gold medallions, the gold foil postmarks really pop and look fantastic. Featuring the outline of a Koala with a joey (baby), they are postmarked “6 November 2024, Canberra, ACT, 2601”.
Reverse

The reverse features similar wording to the reverse of the original series:
“Our iconic Koala (Phascolarctos cinereus) is facing a crisis. In its native habitat on the eastern and southern coastal regions of the mainland, the Koala is at risk, and in Queensland, New South Wales and the Australian Capital Territory, this much-loved marsupial is listed as an endangered species under national environmental law. The dramatic decline in populations can be attributed to habitat loss, climate change and associated extreme weather events, including bushfires and flood. The destruction and fragmentation of habitat means Koalas must spend more time on the ground moving from tree to tree. This makes them much more vulnerable to being hit by cars and attacked by dogs, while elevated levels of stress make them prone to sickness and disease. Sadly, many Aussies are unaware we’re at risk of losing this treasured species. We need more people to advocate for nature, to become Koala champions and build awareness of the threats that are pushing Koalas to extinction. That’s why Australia Post is supporting World Wide Fund for Nature Australia (WWF-Australia) in its goal to double the number of Koalas across eastern Australia by 2050. This includes supporting efforts to protect and restore Koala habitat and to keep Koalas safe from disease.

Koalas

I realised after writing up the piece on the original “Koalas in Danger” series, that I never really covered what a Koala actually is. So, let’s do that now.
The scientific name is “Phascolarctos cinereus”. BushHeritage Australia describes Koalas as: “Koalas are possibly our most iconic native animals; instantly recognisable worldwide as a symbol of Australia and found nowhere else. These tree-dwelling marsupials are the only surviving members of the Phascolarctidae (Greek for ‘pouched bear’, although as marsupials, they are not bears) family, whose closest living relatives are the wombats.
Weighing 4kg to 15kg, Koalas are among the largest tree-dwelling marsupials. Males are up to 50% bigger than females.
Mostly active at night, with their sharp claws and opposable digits, Koalas are most at home high in the tree canopy and come down to ground only to move trees or to another habitat patch. They get all the moisture they need from gum leaves and only need water in times of drought (when leaves dry out).
Perched high in gum trees, with their stocky, tailless body, large heads and fluffy ears, Koalas live almost entirely on eucalyptus leaves, which are tough to digest. As a result, they’ve developed a very slow metabolism to save energy – in fact they can sleep for up to 20 hours a day!
There are more than 700 species of eucalypts and Koalas are quite fussy eaters – only around 50 are suitable and around a dozen make up their staple diet. Koalas can only absorb about 25% of the nutrients from the leaves, and the rest is excreted as undigested fibre. So, they need to eat a lot of leaves – adults will put away around 500g to 1kg of leaves each night.
