Each deal has it's own expiry. Travel dates are: 20 Jan 2020 - 31 Mar 2020, 20 Apr 2020 - 15 Jun 2020, 15 Jul 2020 - 15 Sep 2020.
Managed to find 25h + 28h return flights in Jan 2020, so going through Melbourne and LA for $1005 per person. Small layovers <2h in each stop. Same price form Melbourne and Sydney, Perth is $350 extra. Seems to be a lot more destinations but hard to compile it all. I did look at the flights for BNE to Narita for example, but there seems to be long flights for the price.
Also available: Using BNE as an example, but check your local airport for similar pricing
