This exhibition, Pobblebonk, is primarily about the animals or fauna of the Maribyrnong River estuary. The purpose of this exhibition is to bring attention to these animals and their habitat so that habitat can be better understood and appreciated with the hope we can continue to keep it alive.

It has been put together with the help, support and input of a number of organizations and individuals with a diverse range of backgrounds and experience.

It is remarkable how many different species, indigenous and introduced, still live in the estuary despite the battering it has undergone with a city growing up around it. It is also remarkable what food chains, food webs and biological neighbourhoods remain relatively intact or workable.

Descriptions and explanations in the exhibition are simple and brief (in many cases no description is given at all) because more detail can easily be found through many other sources. The exhibition is more an introduction or a presentation of these wonders in our own neighbourhood.


The lower Maribyrnong River is an ‘estuary’, which is that part of the river that meets, and is affected by the sea; or Port Phillip Bay in this case. The estuary has a very different character from the familiar, freshwater river upstream as it is influenced by both the salty waters of the Bay and the freshwater that flows into it. The Maribyrnong River has a long estuary, about 15 kms, that extends from the confluence with the Yarra upstream to Solomons Ford at Avondale Heights. Near its mouth, in the Port of Melbourne, the river is very deep, having been dredged to a depth of 10 metres. Above the Port, for most of its length, the estuary generally ranges from two to four metres in depth.
