Jacqueline Wilson is a WWI direct descendent and was one of 10,000 picked from a ballot of 42,000 people to attend the ceremony. She will arrive in Gallipoli on April 24 at 6pm to sleep under the stars before the 5am dawn service, then hot foot it 3km to Lone Pine for the 11am service. While she knows the expedition won't be a piece of cake, her family told her she'd kick herself if she didn't go.

"My father fought there and it's going to be vey special to me. It's a once in a lifetime experience," Mrs Wilson said.

"I spoke to my family about it and they are very keen for me to go and very supportive."

Her father, Sydney Harold Treloar, was a part of the sixth Light Horse Regiment and spent from September to December 1915 in Gallipoli.

He was 25 when he went to Gallipoli with his younger brother and they arrived back in Egypt on Christmas Day.

They then went on to Marseilles in June 1916 before fighting in the Battle of Fromelles.

In Passchendaele (Battle for the Battle of Polygon Wood) the group was severely gassed.

"After being gassed, my father spent almost seven months in and out of hospitals, both in France and England, and finally was sent back to The Front," Mrs Wilson said.

"This happened the first week of September 1918 and he re-joined his battery preparing for the Battle of St. Quentin Canal. His Howitzer gun was hit on September 29 and he carried the shrapnel in his wound for the rest of his life. He arrived back in Australia in May 1919 on a hospital ship."

He met his wife while he was in Wentworth Falls Chest Hospital suffering from tuberculosis and after he was cleared they were married and moved to Beckom.

He set up the local Returned Sailors', Soldiers' and Airmen's Imperial League of Australia (RSS and AILA) in Beckom and was the president for about 18 years.

Mrs Wilson has spent 14 years researching her father's life, as he passed on July 26, 1942 when she was a young girl.

She has learnt a lot from his service record, even though the year of 1917 was missing.

"Now I realise the questions I needed to ask but back then it just wasn't talked about," she said.

"I know my father more now than I did as a kid. I've spent a lot of time in the research department of the War Memorial (in Canberra)."

She went to Gallipoli in 2000, toured the area and attended the Anzac Service when the crowds were not as big as they are today.

"I think people are becoming more and more aware of the significance of ANZAC and the battle at Gallipoli," Mrs Wilson said.

"Although it was our biggest failure, the cohesiveness it produced of that national feeling of being Australian and protecting our country, keeping it free, is quite unique."
