There were three versions of the survey run in the same experiment. The first version had three unlabelled alternatives, while the other two versions differed only in that the alternatives (Option A and Option B) were labelled. The second version identified whether an Eradication or Containment control strategy would be pursued by including those as labels. For this version, the experimental design was tailored slightly to show that the eradication policy tended to have higher cost levels but would result in lower levels of impact compared to a policy of containment. The third version involved labelling the alternatives as having High Certainty or Low Certainty that the controls would be effective, with the same attribute levels as used in the first version. The final survey instrument involved five key sections: 1. Background information to define the issues and refer respondents to further information if required, 2. Collection of data about knowledge, attitudes and experience with red imported fire ants, 3. A series of 10 choice sets and followup questions 4. A contingent valuation survey about biosecurity and 5. Collection of data about respondent characteristics. The survey was conducted in an online format with a private organisation employed to host the survey and to provide access to an internet panel of Brisbane residents. Three hundred and twenty nine respondents were surveyed from the Brisbane metropolitan area, with similar proportions answering each of the three versions.
