Based on tests to the Australian standard for portable cots, AS/NZS 2195:2010. Any supplied accessories such as bassinets and change tables are also assessed and factored into the score. The lower the score, the more significant the safety failures found. See the bad points for each model for details of any failures.
Whether the model passed the most important safety tests of the Australian Standard, AS/NZS 2195, such as having breathable mesh on all sides, and having no suffocation or strangulation hazards. Some models that pass the key tests still have some minor failures and therefore aren't fully recommended, but are still worth considering.
