Seoul nonstop from Sydney for $887 on Qantas. With the crazy high prices of flights around right now these are a good deal!
Note that to get this price you have to book through an NZ OTA. You can book directly through Qantas if you prefer but it brings the price up to $949.
Dates in March, late April, May, June, August and September 2023.
Similar prices from other departure cities but with a stop en route in Sydney.

Actually I saw some good ones recently—You don't say anything about dates or city, but SYD - GRU (Sao Paulo) $2108 https://www.google.com/travel/flights/search?tfs=CBwQAhoeagc…
or to Rio for $2128 https://www.google.com/travel/flights/search?tfs=CBwQAhoeagc…
Aren't bad considering current prices and how far away Brazil is!
