Using Twitter to access Government-held information

The UK Information Commissioner has stated that a tweet can be a valid Freedom of Information application if certain conditions are met. 
As long as it--
is communicated to the relevant department using the "@” function, for example @Department of Housing
states the name of the applicant, which can be satisfied by a name on a person’s twitter profile; and
states an address for correspondence, which could be the person’s Twitter by way of using the "@" function, for example @TwitterUser, or an email address
--it can be considered a valid application.
The UK Information Commissioner provides further guidance on Twitter as an FOI mechanism in their July newsletter, which can be viewed here: http://www.ico.gov.uk/news/enewsletter/previous_enewsletters/English/201107.aspx#story10.

Queensland context
It is unlikely that Twitter could serve as a valid method of making an RTI application in Queensland. If agencies with Twitter accounts receive tweets which appear to be an attempt to make an RTI applications by way of the @Department function, they should take steps to contact the Twitter user to assist them to make a valid application.
