Interesting, not what was initially reported. I definitely read it was a pen originally but I believe it was an early article that has since been edited by the ABC.
There’s nothing that really reports what the weapon is that I can find just verbs of ‘stabbed’ and ‘knifed’.
This blew my mind as an Australian, I had a 9.9kw system installed for about $3200AUD from memory, there was a rebate but I’m unsure how much.
I get a minimum like 18kw a day on really cloudy days and up to high 50s on a good summer day. No batteries but it’s drastically reduced my power bill.
