If size does matter then this is the biggest bang for buck, a massive screen TV from one of Korean big 2.
4.7 stars out of +700 reviews look good.
Use JB Hifi 3% discount GCs to save more (e.g. Shopback app, buy 2x$200, 1x$500 and 1x$1000).
Does not seem to provide delivery option.
Also Samsung TU8000 65" Crystal UHD 4K Smart TV  $922.45 in store only ($897.45 with Latitude Pay).
P.S. Sorry Perth and Adelaide, does not seem to be available within 200km of your metro post codes. See below to buy direct from Samsung with free delivery, especially if you think about adding a Samsung soundbar system as they give an extra $250 off.
*If your local JB does not have it and/or you need delivery, Samsung has just discounted it to $2024 including delivery. Sign up to their online store to get $50 off. This is not bad considering most online appliance stores charge around $120-160 shipping for large TVs (if they do at all, especially to WA or regional areas)
Also noting that if you buy a sound bar from the Samsung store at the same time as the TV (75" or 82"), you'd get $250 off the combined total (spotted by cjmorgan87). I'd recommend HW-Q600A 3.1.2ch Home Theatre Soundbar $669 including delivery which supports both Dolby Atmos and DTS:X. It's currently on sale at JB for $599 + delivery, so the Samsung price is quite close. But Samsung will take an extra $250 off with the TV.
