Yes. And those accusations were true. And, quite possibly, these Australian accusations are also true. It may or may not be a convenient truth, or a truth withheld until a convenient time, or a similar truth about the other party might also be known to be true but not released. Or maybe Labour really is the more corrupt party and ASIO are earnestly working to protect Australian interests. All of these hypothesis are congruent with the evidence.
There's a difference between being skeptical of politically convenient press releases versus being a contrarian that just assumes anything politically convenient must be a lie.
