Another great hyperlink on the wiki is "CONTESTABILITY:Selected Historian Sources on Gallipoli". This is found in week 4/5 on the SOSE wiki. This is a great site for references and evidence for the historians point of view on the significance on the Gallipoli Campaign and the ANZAC Legend. It was very useful to me.
There is a great hyperlink on the MSM wiki that is in week 4/5, it is called "Gallipoli & Beyond Text: Ch16 Anzac Legend.pdf pp.170-178".

This reference is from the Australian War Memorial so it is very trustworthy. It has stated on the site how many Australians died in the Gallipoli Campaign. There is a table which describes the people who died in action, from diseases, wounds and gives you the month these soldiers were killed in.
This website gives you a brief overview about the commemoration, the ANZAC Legend, the Gallipoli Campaign and the ANZAC spirit. Throughout the site, there is some sources that could be used as well. Down the bottom of the page is hyperlinks to many great websites. These websites are based on the information that was talked about earlier but goes into a lot more detail.
This website helped me a lot. On pages 10 onwards, there is many primary sources. In the sources there are images, letters from the soldiers and newspaper articles from 1915. The newspaper article on this website was the first article released to the Australian public about the Gallipoli Landing. These were very helpful and contributed to most of my inquiry questions.
I had a lot of trouble understanding the ANZAC Legend and this website really helped me. It has lots of great information and it has other sections on the website about the Gallipoli Landing and the Campaign.
