I think that on "character grounds" in assessing a visa application the Dept of Immigration would have to be very creative when assessing one lodged on behalf of Hunter Biden.
Whilst on the subject of Hunter isn't it quite amusing how the treatment of the "news" around the discovery of what was on his lap top was "Russian disinformation" before the election of ole sleepy Jo? Yet now 'it ain't so'. Funny that. This is what worries me about the current proposal for laws around spreading "disinformation". Who will be the arbiter?
