Yep, the Targus Universal Power Travel Adapter (APK01US1) does work in Australia. According to the manufacturer's description, it handles various plug formats, including the Type I sockets used in Australia. So, you should be good to go when you travel there with this adapter.
Just a heads-up: Make sure you're buying the real deal. Our research found that genuine Targus adapters come in plastic shell packaging with the Targus logo and some documentation.
If it shows up in plain packaging without branding, it's probably a fake. There have been some complaints about non-branded versions from certain sellers, which is a bummer.
To avoid this hassle, it's better to buy from reliable sources, like when it's 'Sold by Amazon.' That way, you'll get the authentic Targus adapter people have reviewed positively for its durability and reliability.
So yeah, as long as you go with a trusted retailer, you should be set.
