- the lack of communication and joint decision-making between Abbott and his Foreign Minister, Julie Bishop (and presumably with her Department (DFAT)).
- that the Australian "Cabinet's top secret National Security Committee (NSC) met in October  and supported a move that would allow the bulk of Australia's submarine fleet to be built offshore."
Abbott has made two conflicting promises: :
1. in 2013 - mid 2014 to South Australia that 12 new submarines would be built in South Australia, and
2. Abbott's request-promise in mid 2014 with Japanese Prime Minister Abe that Australia wishes to buy 6-12 new submarines from Japan (and built in Japan).
When Abbott's position as Prime Minister is threatened (as in February 2015) he quickly needs to juggle Promises 1 and 2. This juggling may occur again.
On March 16, 2015 Australia's ABC aired a 4 Corners program called "House of Cards" (video and transcript here) that recalled Abbott's juggling of Promises 1 and 2. See shorter report of ABC program (below). This juggling occurred on February 8-10, 2015 when Abbott told Liberal-National Party Coalition politicians that he would allow ASC to participate in an "open tender". This appeared to be a decision moving in the direction of Promise 1, as it would make it possible for Germany, France and Sweden to win and then "build in Australia".
By February 10, 2015 Abbott had apparently forgotten the "open tender" promise and had replaced it (or returned it) to "competitive evaluation proces" generally assumed to mean ASC could play a small part of "build in Japan". "Despite press speculation at the time, the [Australia's National Security Committee (NSC)] did not make any final decision to build the submarines in Japan." However it was assumed by many in the Federal Government and the South Australian Government that the build would occur in Japan (see article below).
