I've been waiting for this for a while, by combining two deals, you can get the Bose Soundlink Mini for $169.
Deal 1 - AMEX $40 rebate: https://www.ozbargain.com.au/node/192897
Deal 2 - David Jones 30% off Bose Sale: https://www.ozbargain.com.au/node/196633
You can also get 1,045 bonus Qantas points through the Qantas Mall OR $14.63 cash back (7%) through Cash Rewards. Total $154.37 if you combine the AMEX rebate, DJs sale and cash back from Cash Rewards.
Compared to the Sony SRS-X3, it's a hell of a lot more expensive (especially if you get the SRS-X3 on sale), similar sound quality, and lacking convenient NFC pairing. However, on the positive side, you can play it while it charges (SRS-X3 ran out of juice on me last night), is smaller, and looks much better (subjective).
Thanks to Fishy for posting the original deal and ozibargainer for the DJs deal.
Dont forget 7% cash-back via cashrewards.com.au!
