As far as Australian poetry goes, I love the works of Banjo Paterson and Henry Lawson. While both poets write about the Australian bush and the outback characters of the late 1800s early 1900s, the mood of each writer is quite distinctly different. Paterson's work tends to be more romanticised and humorous, possibly due to his affluent and comfortable background, while Lawson is more of a realist, portraying the harshness of outback life, 'warts and all'.
I also enjoy the poetry of the Indigenous Australian poet Oodgeroo Noonuccal (Kath Walker). She was also a political activist, artist and educator and wrote many powerful works about the plight of her people in the wake of colonisation. I first read her poems as a school girl and have enjoyed them ever since.
As far as English poetry goes, I love the works of the Romantic poets, especially that of William Wordsworth and John Keats as they were so sensitive to the moods of nature and expressed their feelings so poignantly. I recently visited Wordsworth's former home Dove Cottage (which is now a museum and literary shrine) at Grasmere in England's beautiful Lake District and was inspired by the breathtaking beauty of the area which he loved so much.
My favourite poet is Philip Larkin. I first studied him while doing my A-Levels, then again in university; he has rally grown on me. My second favourite is Seamus Heaney. I was saddened to hear that he had died. They have both inspired my own poetry.
I'm partial to Robert E. Howard, even though he's not primarily known for his poetry. It was only when I started reading his poems that I realized that poetry need not be just soft or silly, it could also be savage and wild.
Rumi - he has written some beautiful poetry in Persian language in the 14th century, but the poems have been translated by Coleman Barks mainly and others. His poems are beautiful. I LOVE him. Rumi is a sufi - a spiritual mystic.
