At Cooloola By Judith Wright

The blue crane fishing in Cooloola's twilight

has fished there longer than our centuries.

He is the certain heir of lake and evening,

and he will wear their colour till he dies,

but I'm a stranger, come of a conquering people.

I cannot share his calm, who watch his lake,

being unloved by all my eyes delight in,

and made uneasy, for an old murder's sake.

Those dark-skinned people who once named Cooloola

knew that no land is lost or won by wars,

for earth is spirit: the invader's feet will tangle

in nets there and his blood be thinned by fears.

Riding at noon and ninety years ago,

my grandfather was beckoned by a ghost－

a black accoutred warrior armed for fighting,

who sank into bare plain, as now into time past.

White shores of sand, plumed reed and paperbark,

clear heavenly levels frequented by crane and swan－

I know that we are justified only by love,

but oppressed by arrogant guilt, have room for none.

And walking on clean sand among the prints

of bird and animal, I am challenged by a driftwood spear

thrust from the water; and, like my grandfather,

must quiet a heart accused by its own fear.

At Cooloola is a lyrical poem written by a well recognized Australian poet, Judith Wright. This poem creatively describes a beautiful scene of nature. The poet uses highly descriptive language and a diverse range of poetic devices to engage the reader into imagining a picture of how peaceful and serene this exquisite the scenery is down by Lake Cooloola. Underlying the subject matter is the implied theme that the lake is under threat from "conquering people" who will not protect its "white shores of sand, plumreed and paperbark". This poem reflects Judith Wright's concern for our special and unique flora and fauna, how fortunate we are to have stunning scenery, how easily mankind can destroy it, and our need to appreciate it.
