I'm gonna generally... disagree with the Greens comments, speaking as a member of the Victorian Green since last year. But I think you're touching on something I've voiced elsewhere, is that Australia's really lacked any strong, charismatic political leaders since Rudd. Everyone since him has either been playing it safe (Turnbull), is an obvious idiot (Abbott), or just isn't all that interesting (Shorten, debatably Di Natale), which leads to a lot of dissatisfaction with the leaders themselves because they neither catch people's attention, nor achieve much of note. I'd argue that's part of why Hanson got her foot back in the door; she might be a terrible person and kind of an idiot (albeit not to Abbott's level), but at least she's a fairly strong public speaker and you know she believes what she's saying. That's a lot more than you can say for either of the big party leaders right now.
I'd love to see Labor win government in the next election, but if Shorten's still leader at the time it will be less because of them winning and more because the Liberals lost far harder. I've been rooting for Albanese or Plibersek to take over from him, they're way better at it, but it doesn't look like it'll happen.
