Deputy Prime Minister Richard Marles has accused the coalition of treating Australia's defence with "contempt" and misleading voters on cost blowouts, including by trying hide an amount worth the entire WA state budget.
Mr Marles, who is also the defence minister, said the former Morrison government had an "abiding culture" of a failure in transparency following the release of an auditor-general review of a Defence investment program worth $134.1 billion.
