Answer:
Australia at the time was part of the British Empire and Commonwealth. With many British troops being tied up on the Western front, Britain used it's colonies by requesting troops from each of the countries to come forward and fight for Britain. Since Australia was one of the colonies, Australians joined up to fight for the British who had joined forces with the French and Russia (the triple entente), and the British and French wanted to relieve pressure on their ally Imperial Russia, by attacking one of of the triple entente's enemies, the Ottoman empire , which was very close to the Russian mainland, separated only by the Black sea. The Ottoman empire was an ally of Imperial Germany, who the entente was already fighting on the Western front (France and Britain) and on the Eastern front (Russia). With swift German victories in the East in 1916, Britain and France wanted to break through and help Russia as it was weakening. The British and French chose to attack the Turkish (Ottoman) positions at Gallipoli, due to it's close proximity to the Ottoman capital, Constantinople and hoped to force Turkey out of the war quickly, and so Britain needed troops, and so called upon Australia to provide the Gallipoli campaign with some.
The Allied Forces, mainly composed of Australians, landed at Gallipoli in 1915.
Australian soldiers first arrived in Gallipoli on 25 April 1915. They remained there for about eight months.
The ANZACs were supposed to land on Cape Tepe but ended up landing on what was later known as ANZAC Cove, two kilometres North of the intended landing place.
April 25 1915 was the landing of Australians troops on the shores of Gallipoli.
ANZAC Day commemorates the day, on 25 April 1915, when the ANZAC troops landed at Gallipoli.
The ANZAC troops were evacuated from Gallipoli eight months after the initial landing which occurred on 25 April 1915.
Over 8,000 Aussies died at Gallipoli and about 60,000 were wounded.

It is not known how many Australian troops were involved in the landings at Gallipoli. However, the entire Gallipoli campaign resulted in 26,111 Australian casualties, and this included between 8,150 and 8,500 deaths. The total number of Allied troops who took part in the Gallipoli campaign was about 480,000, but this included Australians, New Zealanders, British and French.
Some 60,000 Australians and 18,000 New Zealanders were part of a larger British force.
