The most recent version of ASDEFCON (Support) is version 5.1.

The ASDEFCON (Support) template has been updated to incorporate changes focused on the CASG 2.0 Procurement Reform Initiative 1: Tender Data Requirements (TDRs) Reduction, with an aim at reducing, consolidating and simplifying the templates as follows:

  • extensive changes made to reduce the size of TDRs including the volume of information requested by Defence
  • simplified drafting across all of the TDRs
  • TDRs which contained ‘like-themes’ have been consolidated to remove duplication
  • reduction of commercial TDRs by relying more on the statement of non-compliance and moving other information requirements from tender and into the negotiation phase.

In addition to the reduction in TDRs, ASDEFCON (Support) V5.1 incorporates the following additional changes:

  • updates to clauses made to facilitate the transfer from legacy Defence information systems to the Defence Enterprise Resource Planning (ERP) System
  • some minor updates, including for Defence web-links (following migration of Defence web pages), and changes in Defence policies and commercial standards.

A table of changes from version 5.0 to version 5.1 of ASDEFCON (Support) (PDF) is available.
