Samsung gives up to $400 cashback for purchasing both its TV and soundbar from the same retailer.
Not valid for auction sites.
So basically you need to buy both TV and soundbar listed here:

It will provide $200 via eftpos or gift card if you buy H551 soundbar, and $400 for H751 soundbar.
These soundbar are Editor Choice everywhere.
Dicksmith currently runs a few promotions on each TVs, but it only sell HW551 on its website. If you can price match the soundbar with other store like TGG, or get the TV from TGG, you should be able to snab a bargain.
Soundbars seem a bit overpriced…
