I have hardly paid attention myself. I see lots of ads on YouTube but that's about it and I ignored them. My early voting place had nobody but it was on a shopping centre so maybe they weren't allowed.
I did see the greens setting up today in the city outside the early voting place that wasn't there last week. Makes sense with all the lunch time voters I guess.
As for polling, I think Antony Green already thinks it's a Labor win but by less than previous years.
One thing I did notice is that if you own the zelda games on switch 1, and have the online sub +exp, you get the upgrade for free. I'm still not sure that justifies it of course but it's something. Still not sure I can spend that much on a console.
