Apparently it includes a parking ticket, a licence plate and a letter from the PM. Its fairly underwhelming list http://www.library.act.gov.au/find/history/search/Manuscript_Collections/hmss-0375-canberra-centenary-time-capsule2
Plaque reads:
'Within the base of the Canberra Centenary Column lies a time capsule containing 100 objects and stories representative of the Canberrans in the city's centenary year. Curated by Craft ACT and coordinated and sponsored by Canberra CBD Limited. Copies of the contents are held in the ACT Heritage Library.
The sculpture is inspired by the never completed Canberra Commencement Columb now in front of Parliament House. Historical images are sourced from the collections of the National Library of Australia, the Australian War Memorial and the National Archives of Australia
Launched by Kay Gallagher MLA, Chief minister of the ACT on the last day of Canberra's centenary year 11th March 2014
To be opened on 12th March 2113
Canberra CBD Limited thanks the Canberra community, the ACT Government, the National Capital Authority and Artillion for their contribution, with construction assistance by GHD, Acclaim Contractors and Pacific Stone.'
