Came across this store when I was looking around for a set of speakers for a home theater system and this is the cheapest I've seen this particular set, especially with the subwoofer included.
I also got the Marantz NR1603 from them in a bundle of sorts so they reduced pricing even further on the receiver too!
It was around $100 for shipping to me as I live in a rural area in Victoria but it should be free shipping to all metro areas for a lot of these items.

EDIT: Noticed the page of the speakers says the special for them ends on 4th of July but they have added it to their 'Start of financial year sale' so it has been continued to be discounted until the end of that sale.
EDIT #2: They've now extended the sale price to the 25th of July.
It's not bad, but the ones from this deal are currently AUD$407 shipped (without sub). Compared to US prices, what we pay for speakers in Australia is beyond ridiculous. There are plenty of good speakers on Amazon US which ship to Australia at a fraction of the local price, including JBL.
EDIT: this (ex-demo) receiver is not bad: https://www.digitalcinema.com.au/Denon-AVR-1611-AV-Receiver-…
