East & West Coast USA from SYD from $898AUD Roundtrip

EDIT: Since posting the flights originating in Australia are not showing up as sale flights anymore. have not tested for every city, but marking deal as expired as I suspect this deal was only meant for travellers originating in the USA (must be promoting people to flee the Trump rein while they still can)
Tested for New York, Philly and DC (multiple dates from april to june)
End Edit

Price works out to start from around $898 AUD to fly return to NYC as an example.
