I obviously can't speak for every user who downvoted or voted to close, but from what I saw in the comments (and my own interpretation) the problem isn't that you asked about hypocritical behavior, but that the behavior you described wasn't hypocritical.
In your question, you said was Australia doing two things that you believed was hypocritical:
- Australia condemned and sanctioned Russia in response to their invasion of Ukraine
- Australia's Minister for Defence said Australia should be prepared for war as a response to China's expanding influence
The two behaviors you described are essentially "Russia shouldn't have invaded Ukraine" and "we should be prepared for war with China". These two policies didn't really seem like contradictory or hypocritical to me, and judging by some of the comments other users felt the same way.
However, as the other meta post you linked says asking about hypocritical behaviors/policies isn't off-topic by default, and I can see a couple ways you could ask about potential hypocrisy in Australia's behavior towards China/Russia
- If Australia condemned/sanctioned Russia for preparing for a potential war with NATO, you could ask why Australia would prepare for a potential war with China in the same way
- If Australia invades the Solomon Islands to stop the deal with China (or if they did a comparable military operation in the past), then you can ask why they condemned/sanctioned Russia for doing the same in Ukraine
