Considering the strong punches of A20 thru A51 (except the camera department), this may not be ideal for everyone but it's outright purchase without going thru JB/TGG Telstra hoops.
In case the price does not show up (website is acting up where if you display All phones, the prices are different compared to the actual product page) - then please refresh the page.

Edit - S9 / S9+ showing OOS @ 12:30pm. S10 still showing in stock.
Isn't Mate 20 Pro a better phone for the same price?
